There are several areas that have hurt the Sox this year. Depth of the position players, Starting pitching and relief pitching.
Position player depth was setup to be a problem by a series of trades and acquisitions that others have highlighted. Craig, Sandoval, Castillo and to some extent Rameriz. These players have been expensive with only Hanley producing at a journeyman level. Meanwhile, like all teams, our players face a 162 game season in tough climates with lots of travel and a strenuous daily routine. They face scientific evaluation of their hitting shortcomings and are bound to feel mentally letdown when their pitching staff doesn't do the job, not to mention the typical stresses of family life. Injuries are a part of the game and often they play through minor ones. Of course players can and do get sidelined during the season and the team management needs to plan for replacements to give regular players rest and to fill in when the guys go on the disabled list. With Swihart, Holt, Hannigan and Young on the disabled list the replacements called up were on the weak side with the exception of catcher. If we have can't miss prospects in Benentendi and Moncada, why not let them fill in?
Starting Pitching
We have Wright, Porcello and Price generally performing as acceptable starting pitchers. I was not a fan of the Price deal due to the length of the contract, however, we would be even more lost in the starting pitching arena without him. ERod has talent but has not developed. Buchholz is not doing the job at all, Kelly seemed to fail as well as the two or three youngsters brought up. Are we not getting major league quality pitching prospects or are we not developing the ones we have? This is a serious question. Farrell was a pitching coach at a prior time. Is there something wrong with the coaching and development of red sox pitching?
Relief Pitching
Some of the problems we have faced here stem from the failures of the starting pitching, which is putting high workloads on our bull pen. Kimbrel was a good acquisition. Koji might just be getting too old. Tazawa is still effective. Hembree is doing a decent job but in general the bull pen needs an infusion of talent. Perhaps Kelly will be moved back to that role but trade or free agency needs to be gone to for more talent.
Alas, I think the Red Sox with retreat to a mediocre record this year and Dombroski will need to set sites on improving for next season.
