How have Dave Dombrowski's in season relief pitcher acquisitions worked out?

The Red Sox have experienced relief pitching woes since Carson Smith went down at the beginning of the season. So much so that Sox have used 19 different players in relief so far this season.

Noting that relief pitching was a team shortcoming, Red Sox team President Dave Dombrowski went out and acquired 2 pitchers to bolster the bullpen.

The question becomes, were Brad Ziegler and/or Fernando Abad the right choices? We'll look at that it a moment.

One thing we should all agree on is it is not to early to judge the moves. When you acquire in-season help, either a bat or an arm, they are brought in to help fill a glaring need. Immediately. There is no time for gestation period.

There were 23 relief pitchers that exchanged hands on or around the trade deadline. Here are the teams that acquired each one and their combined stats since being traded.

Did Dombrowski get it right? You make the call.
