Pitching is a great topic for resuming A Realistic View of 2021, part deux.
Dgalehouse is adamant that the Sox have too many pitchers: right now they do in fact have 12 position players and 14 pitchers (6 starters and 8 relievers).
But I think that is the right mix because you can never have too much pitching, especially when the Sox need quantity to make up for a shortfall in quality starters. In the latest (4 games) Yankees series the only starter to get a win was the Yankees Taillon. The bullpen got all 3 of the Sox wins--and last night Ottavino got the win vs. Toronto.
The six starters address moonslav's big point about getting another one because, even with Sale returning (mid-August?), Eovaldi a semi-ace (WAR 3.0), and Houck looking pretty good this time up, the other four--Pivetta (the best of the worst), Perez, ERod, and Richards--do not inspire confidence. Thus too the 8 relievers (currently without Sawamura, WAR .6): Barnes (WAR 1.8), Whitlock (WAR 1.8), Ottavino (WAR .9), Valdez (WAR .5); backed up by two lefties, Taylor and Hernandez (WAR's .7 and .6), and two last resorts, Rios and Workman (.4 and .2).
Plus don't forget that Cora's managing of the 2018 postseason demonstrated how starters, regardless of stature, can quickly become relievers with the only criterion being, "can he get guys out?"
Also a word about the lineup. Even with a bare bones 12 position players, Cora has been able to rest all his best players and rotate beaucoup guys through CF, 2b, and 1b in an effort to find and keep the best bats and to compensate for Arroyo going on and off the IL. Right now Duran with his speed and lefty bat and reputed potential is getting a shot, just as Dalbec has all season long, Chavis has now and then, etc.
But the simple fact is that Cora wants these seven (7) bats in the lineup as much as possible: Devers, JDM, Bogey, Hernandez, Verdugo, Renfroe, and Arroyo. And the 8th bat belongs to Vazquez, who has a lock on catcher (4 of 5 games) because his DWAR is 1.2 (only Hernandez's 1.5 is higher) and his OPS of .645 is par for a catcher.
Thus Chavis, Dalbec, Duran, Gonzalez, Santana, and Cordero have all basically been trying out to become the 9th bat and/or fill in for Arroyo. And Hernandez, easily our best centerfielder at bat and in centerfield, gets jerked around so that Cora can keep searching for that 9th bat.
