The Red Sox are officially the last to double digit losses.
Also, if the Sox win 1 of the next 2 games, they will be the first to 20 wins. At 19 wins, they are 2 ahead of the second closest (Rangers, Yankees, Braves, & Rox all at 17).
Through 27 games, the Sox have a +47 run differential. That's best in the bigs, and it's not close. Coming in 2nd place is a tie between the Rangers, Braves, and Rockies, all at +29. Yep. That's a difference of 18 runs between 1st and 2nd, and a 162% increase.
The Red Sox SP ERA (3.10) is 1st in the AL (Detroit #2 at 3.23). Their team ERA is 3.49, second in the AL. Surprisingly, the bullpen has severely underperformed thus far (4.34 ERA), but the back end (Taz - Uehara - Bailey) have been elite, throwing 35.1 IP to a 2.02 ERA.
