Sox have been better on the road all season long: 34-24 vs 27-28. What's neat is that, following a horrible start to the post-ASG season when the Sox went 2-7 against the Dodgers, Rockies, and Yankees, they have now gone 6-3 while winning series vs the Mariners, Rangers, and Royals.
And, just as you say, the pitching--rotation and bullpen--has nosedived since the ASG and is now ranked 16th in MLB in team ERA. Plus you have to tack on a bunch of unearned runs, which I believe the Sox have more of than anyone else. For maybe the first two months the Sox team ERA was 1st in MLB.
On the other hand--as you also point out--the no-names in the lineup (except Devers and Duran, both on the AL All-Star team) have blossomed to the degree that the Sox are 4th in MLB in runs scored and tied for 1st in team OPS.
We are already at the point where every game seems to count more than all the games before. We are in August and moonslav keeps reminding us how our near competitors did that day/night. And I keep reminding everyone that the AL East still has easily the best W-L record of the 6 MLB divisions. That gives the Twins and the Royals an edge on us.
FWIW, these are the WAR's and ERA's of the 13 pitchers on the current roster:
Houck, 2.6 and 3.09;
Crawford, 1.6 and 4.11;
Kelly, 1.4 and 2.49;
Jansen, 1.3 and 2.95;
Pivetta, 1.2 and 4.44;
Booser, 1.0 and 2.77;
Bernardino, 1.0 and 3.03
Winckowski, 0.6 and 3.44
Martin, 0.4 and 3.29
Bello, 0.1 and 5.16
Criswell, 0.0 and 4.02
Garcia, 0.0 and 6.00
Paxton, -0.1 and 4.35.
What's misleading about the above is that Houck and Crawford have both been terrible since the ASG: Houck, 3 starts, 17 IP, 13 ER; Crawford, 3 starts, 13.2 IP, 16 ER.
Pivetta was awful his first post-ASG game, 2.2 IP and 7 ER, but decent in his next two: 6.2 IP and 3 ER; 4.2 IP and 2 ER.
Bello has been decent since the ASG: 5 IP, 3 ER; 6.1 IP, 2 ER; 4.2 IP, 3 ER.
So has Paxton: 4.1 IP, 3 ER; 6.0 IP, 2 ER.
Winck and Criswell have stayed in the bullpen since the ASG.
