Arizona Diamondbacks – Biggest Weakness: Catcher
The Diamondbacks were decent at the catcher position last season, but they let starter Chris Iannetta leave in free agency. However, the Diamondbacks are seriously struggling at the catcher position in 2018. Jeff Mathis is a good defensive catcher, yet he is only hitting .182 with no home runs this season. The Diamondbacks also have Alex Avila at the position and he has been even worse while batting .148 this season. It is hard to find good offensive catchers these days, but Arizona needs much better production than what they are getting right now.
Atlanta Braves – Biggest Weakness: Bullpen
The Braves have a really good starting rotation, but issues arise when they have had to call upon their bullpen this season. Arodys Vizcaino has been terrific as the team’s closer, but the rest of the bullpen has been very inconsistent. Shane Carle, A.J. Minter, and Dan Winkler have been good at times. However, none of those guys have been the reliable relief pitchers that Atlanta needs. If Atlanta is going to make the playoffs this year, then they need to find some better late-inning options in the bullpen.
Baltimore Orioles – Biggest Weakness: Starting Pitching
Baltimore has been terrible in many different aspects, but starting pitching stands out as being the worst of it all. Dylan Bundy has been the best starter for the Orioles, but even he only has an average 4.08 ERA this season. Kevin Gausman has been decent as well with a 4.11 ERA, but he has been inconsistent as well. The rest of the rotation though has been completely awful as the offseason free agent signings of Andrew Cashner and Alex Cobb have just made the rotation worse. Also, Daniel Hess and Chris Tillman both have absolutely terrible ERA’s as well. Baltimore has had terrible starting pitching for years, yet it might actually be worse than ever this season.
Boston Red Sox – Biggest Weakness: Catcher
Sandy Leon performed well offensively in 2017, but he has regressed so far this season as he has become the weakness of the Red Sox lineup. Leon still hasn’t been terrible, yet he is only averaging .252 with 4 home runs in 2018. Meanwhile, Christian Vazquez has been even worse offensively for Boston. Vazquez is hitting .213 with 3 home runs in 2018 despite getting even more at-bats than Leon. Boston has enough in their lineup to make up for the lack of production at the catcher position, although they will need more if the Red Sox really want to reach their full potential.
Chicago Cubs – Biggest Weakness: Starting Pitching
Jon Lester has been outstanding for the Cubs this year as he has a 2.45 ERA. However, the rest of the starting rotation for Chicago hasn’t been nearly as good. Mike Montgomery has been decent as a 5th starter for the Cubs, but they need much more from the other pitchers. Kyle Hendricks, Jose Quintana, Tyler Chatwood, and Yu Darvish have all underachieved this season. The Cubs are still a probable playoff team, but if the Cubs want to make a deep playoff run then they’ll need much more from their starting pitching.
Chicago White Sox – Biggest Weakness: Starting Pitching
Reynaldo Lopez has been the lone bright spot in the White Sox starting rotation as leads the White Sox starters with a 3.77 ERA. However, the rest of the White Sox starting pitchers have been disastrous to say the least. James Shields, Dylan Covey, Lucas Giolito, and Carson Fulmer all have been really awful. Giolito and Fulmer are still big parts of the rotation for the future, yet Chicago needs much better starting pitching if they ever want to be relevant again.
Cincinnati Reds – Biggest Weakness: Starting Pitching
Tyler Mahle has been outstanding with a 3.66 ERA this season and Matt Harvey has been good for the Reds as well with a 3.79 ERA in 11 starts for the team. However, the rest of the rotation hasn’t been good at all. Sal Romano, Luis Castillo, and Homer Bailey all have an ERA 5.28 or less this season. The good news is that the Reds have a very good offense, but they will need much better starting pitching if they want to compete anytime soon.
Cleveland Indians – Biggest Weakness: Center Field
Bradley Zimmer and Greg Allen have both split time in center field for Cleveland this season, but the issue is that neither of them have been productive offensively. Zimmer is hitting only .226 with 2 home runs this season. However, Greg Allen has been even worse as he is a .208 hitter with just 1 home run. Cleveland might need to consider adding a center fielder at the trade deadline since they are getting terrible production from the position right now.
Colorado Rockies – Biggest Weakness: Bullpen
Colorado made some major changes to their bullpen this past offseason, but it has only seemingly made that unit even worse than last season. Adam Ottavino has been terrific and Scott Oberg has been good as well, but the rest of the bullpen has been terrible. Wade Davis was supposed to be an elite closer for the Rockies, but he instead has a mediocre 4.04 ERA this season. Also, Bryan Shaw, Jake McGee, Chris Rusin, and Mike Dunn have all been awful this season. The Rockies have some proven relief pitchers, yet for whatever reason they just haven’t been able to produce this season.
Detroit Tigers – Biggest Weakness: Designated Hitter
Victor Martinez has had a terrific career, but at this point he is nothing more than a mentor for the young players on the Tigers team as he finishes out his likely final MLB season. Martinez certainly isn’t the player that he once was as he is currently 39 years old and he hasn’t been a good hitter at all. Martinez is hitting .240 with just 4 home runs for Detroit this season despite making $18 million in salary. Those aren’t great stats especially for a designated hitter that is supposed to help carry the Tigers offense.
Houston Astros – Biggest Weakness: Bullpen
The Astros are a world series contender once again this season, but they certainly don’t have a bullpen worthy of that distinction. Ken Giles was supposed to be the closer this season, but he has been awful with a 4.11 ERA. Will Harris is another late-inning option for the Astros that has really struggled this year as well. Joe Smith has been the worst of all with a 4.70 ERA in 2018 for Houston. Hector Rondon, Tony Sipp, and Chris Devenski have been the reliable relief pitchers for the Astros. However, that isn’t exactly an inspiring group of relievers especially for a team that could make a deep playoff run. Either way, Houston needs to make it their priority to find some much better late-inning bullpen options at the trade deadline.
Kansas City Royals – Biggest Weakness: Starting Pitcher
It’s never a good sign when a pitcher that has been in the bullpen for most of his career is the best starting pitcher that the team has. However, that is the case with the Royals as Brad Keller has basically been the ace of the Royals rotation with a 2.82 ERA in 7 starts this year. Veteran Pitchers Danny Duffy, Ian Kennedy, and Jason Hammel were supposed to carry the starting rotation for Kansas City this season. However, all three of those guys have an ERA of 4.89 or lower. Meanwhile, Jakob Junis had a terrific start to the season, but he has been absolutely recently. The Royals need to find some better young starting pitchers or else their rotation might be bad for awhile.
Los Angeles Angels – Biggest Weakness: 2nd Base
Ian Kinsler was acquired by the Angels in order to be a major upgrade at the 2nd base position, but he has performed probably even worse than what the team had before. Kinsler has dealt with some injuries this year and that might be a contributing factor to his poor performance, but there is no excusing his .213 batting average. Kinsler has been a major weakness in the Angels lineup and he is holding them back from reaching their full potential.
Los Angeles Dodgers – Biggest Weakness: 2nd Base
The 2nd base position has been somewhat of revolving door as they really haven’t had a clear starter at the position. Logan Forsythe has been the starter for most of the season at 2nd base, although he has been absolutely awful offensively. Forsythe is hitting only .199 this season with just 2 home runs for the Dodgers. Veteran 2nd baseman Chase Utley hasn’t been much better as he is only hitting .227 with 1 home run this year. Either way, the 2nd base position has been a major weakness for the Dodgers and it is something that needs to be fixed soon.
Miami Marlins – Biggest Weakness: Starting Pitching
Miami hasn’t really had a clear ace of their starting rotation since the death of Jose Fernandez and they still don’t have one. Jose Urena has been the best Marlins starter this season, although he only has an average 4.13 ERA. Caleb Smith has been decent as well, but the rest of the rotation hasn’t been good at all. Dan Straily has really underachieved this season as he was supposed to be the ace of the rotation. Also, Trevor Richards and Wei-Yin Chen have been absolutely awful this season. Miami has some decent players in their lineup, but they need to find some better starting pitchers soon.
Milwaukee Brewers – Biggest Weakness: Catcher
The Brewers have used four different catchers this season, but the problem is that none of them have been good. Manny Pina has seen the most action at catcher for the Brewers, yet he is hitting just .227 with 16 RBI’s in 2018. Also, backup catcher Erik Kratz has been even worse with a .210 batting average and 6 RBI’s. Milwaukee has a good lineup otherwise, but they need to find some help at the catcher position if they want to make a deep playoff run.
Minnesota Twins – Biggest Weakness: Designated Hitter
Minnesota added Logan Morrison this offseason as they were hoping to add some power to their lineup. Morrison has accomplished that to some extent as he has hit 10 home runs this year, but the issue is that he hasn’t hit much of anything else. Morrison is batting just .193 for Minnesota this season and that just isn’t good enough. The designated hitter position is supposed to have a player that is a good hitter, but Morrison hasn’t lived up to expectations for the Twins.
New York Mets – Biggest Weakness: Catcher
The New York Mets had a big void at the catcher position which is why they acquired Devin Mesoraco early in the year from the Cincinnati Reds. However, Mesoraco hasn’t exactly been the solution at catcher as he is hitting just .232 with 18 RBI’s this season. Also, his backup Kevin Plawecki has been even worse as he is hitting .217 with just one home run for the Mets this year. The Mets have struggled mightily offensively this season and the catcher position has been a major source of those issues.
New York Yankees – Biggest Weakness: 1st Base
1st Base has been a revolving door for the Yankees this season as they have started a few different players at the position. They started out with Tyler Austin at 1st base, although he hit just .223 before being demoted to Triple-A. Meanwhile, Greg Bird has provided some power with 6 home runs, but he is only hitting .207 this year. The Yankees have even put Neil Walker at 1st base a lot and that has been disastrous as he is only hitting .197 with 2 home runs this season. The rest of the Yankees lineup is really good, but they need to find somebody that can produce more at 1st base.
Oakland Athletics – Biggest Weakness: Catcher
Jonathan Lucroy was once an all-star caliber catcher in the MLB, but he hasn’t really been an average catcher for the Athletics this season. Lucroy is hitting just .245 with 1 home run for Oakland in 2018. His backup Josh Phegley has been worse as he is batting just .219 with 2 home runs for the Athletics this year. Oakland really needs to find a new starting catcher because the position has just not been good this season.
Philadelphia Phillies – Biggest Weakness: Shortstop
Scott Kingery was an elite prospect coming into this season for Philadelphia and there were high expectations for him as the starting shortstop. However, Kingery has failed to live up to expectations as he is hitting just .229 with 4 home runs this season. Pedro Florimon has been better in his limited time at shortstop as he is batting .263 with 2 home runs this year. The Phillies have been rumored to be interested in Manny Machado and they could really use him at this point because they are really struggling at shortstop.
Pittsburgh Pirates – Biggest Weakness: Shortstop
Jordy Mercer is just an average shortstop and he probably always will be, but he especially hasn’t provided much offense this season. Mercer is hitting just .242 with 5 home runs for Pittsburgh as he has basically been the everyday player at that position. The Pirates need to finally find an upgrade at the position because Mercer isn’t worthy of being their starting shortstop.
San Diego Padres – Biggest Weakness: Shortstop
Freddy Galvis is certainly known for his defense and that is probably the only reason that he remains a starting shortstop at the MLB level. However, he has been a liability offensively for the Padres this season as he is batting just .234 with 4 home runs. Galvis makes the Padres a better team defensively, although the team needs to find a shortstop that can provide much more on offense.
San Francisco Giants – Biggest Weakness: Left Field
Hunter Pence was once an all-star caliber player, but his performance has really dropped off this season. He is hitting just .208 with no home runs in 2018 for the Giants as he has been a major liability in their offense. Gregor Blanco has also seen some time in left field for the Giants, but he hasn’t been much better as he is hitting just .242 with 1 home run. The Giants need to find more production from that position especially if they want to remain in the playoff race.
Seattle Mariners – Biggest Weakness: Catcher
Mike Zunino has spent quite a bit of time on the disabled list this season, but he hasn’t even been productive when he has been healthy. Zunino has provided great power as proven by his 12 home runs, but the problem is that he doesn’t do much else on offense. Zunino strikes out way too much and he is only hitting .189 so far this year for the Mariners. David Freitas and Chris Herrmann are the other catchers on the roster right now, but they haven’t been any better. Freitas is hitting just .194 with no home runs while Herrmann is batting .222 with 1 home run this year. The Mariners have a good lineup otherwise, yet the catcher position could hold them back if they make the playoffs.
St. Louis Cardinals – Biggest Weakness: 2nd Base
Kolten Wong has basically been the everyday starter at 2nd base, but he hasn’t exactly proved that he is deserving of being the starter. Wong is hitting just .221 with 7 home runs for the Cardinals this season as he has been the weakest part of their lineup. The Cardinals need to find an upgrade at that position especially if they want to compete with the Brewers and Cubs in the NL central.
Tampa Bay Rays – Biggest Weakness: Right Field
Carlos Gomez was once a terrific starter at the MLB level and that is the main reason the Rays signed him to see if he can provide that type of play to the team. However, it hasn’t quite worked out that way so far as he is batting just .206 with 7 home runs this year. Gomez has been the everyday starter in right field, but the Rays need to find an upgrade at that position since it is holding the lineup back.
Texas Rangers – Biggest Weakness: Catcher
Robinson Chirinos has basically been the everyday catcher for the Rangers this season and he has provided some good power with 11 home runs. However, he has struggled to make contact as proven by his .204 batting average this year. The Rangers have been so bad at the position that they have utility infielder Isiah Kiner-Falefa as the backup catcher. Texas needs to find an upgrade at the position because that duo just doesn’t provide the offense necessary to help out their lineup.
Toronto Blue Jays – Biggest Weakness: Catcher
Russell Martin was once an all-star catcher, but he has not been good the past couple of seasons for the Blue Jays. He still provides some power as he has 6 home runs this season, but he is only hitting .173 so far in 2018. Backup catcher Luke Maile has been better, although he is still only hitting .234 with 3 home runs. Russell Martin isn’t the player that he once was and it is about time for Toronto to find an upgrade at the position.
Washington Nationals – Biggest Weakness: Catcher
Matt Wieters wasn’t performing well as the starting catcher for the Nationals as he was hitting just .232 for the team before getting injured. His injury just weakened what was an already bad group of catchers. Pedro Severino has seen the most playing time since the injury, although he has been awful as he is batting just .171 with 2 home runs. Backup catcher Spencer Kieboom has been somewhat better, yet he is still only hitting .222 with no home runs. Washington is likely in the market for a catcher at the trade deadline and they really need to find at least an average catcher to help improve their lineup.
