As the Sox finish out the season fairly well, a continuing problem is the bullpen.
Some stats on closer by committee. A combination of Junichi Tazawa, Craig Breslow, Robbie Ross Jr (who had a shaky win Saturday and a save Sunday) Alexi Ogando, and Tommy Layne have 20 saves out of 31 tries. Their combined ERA is 4.19. Their WHIPS range from 1.30 to (Ross) to 1.50 (Breslow)
Tazawa is the most disappointing. His slash is 2-7/4.14/1.333 He leads the majors with 7 blown saves, most in baseball. A competent setup man, the righty from Japan has been shut down for the season, possibly because of overwork.
