Yeah, that makes more sense. 2013 only had one big bat, Ortiz's, vs. this year's three, but had a deeper lineup and, in the first half of the season, three pretty good starters in Lester, Lackey, and Buchholz (13/16 starts were quality starts, ERA for season 1.74) before he went on the IL. Lester was 4-1 in the postseason with a 1.56 ERA and Lackey was 3-1, ERA 2.77. Uehara had 7 saves, ERA .66.
This year's team has good hitting overall and is 2d in MLB in scoring. Team ERA is 14th, largely because the rotation is inconsistent. Eovaldi right now deserves to be called the Sox's ace, but he's been shelled three times (6, 5, and 5 runs). I think his splitter has been the big difference because it allows him to throw fewer fastballs, which will be hit when he throws a lot of them. Pivetta is almost as capable as Eovaldi, but far more inconsistent as demonstrated in his last 3 starts: fantastic (6.2 innings, no hits or runs), horrible (6 runs, 4.1 innings), and great (7 innings, no runs, 2 hits). Perez, Richards, and ERod trail behind although ERod seems to be coming around in his last 2 starts: better mix of pitches and much better command.
Looking back over the past 3 months, I think the bullpen has been the key to a big chunk of those 53 AL-leading wins because they are deep and because Cora has managed them awfully well. The bullpen has allowed the Sox hitters to come back against other teams whose bullpens aren't as deep and to hold onto leads when the Sox starters have pitched well.
