Tonight, the Yankees finish their season series with the Boston Red Sox, as Jordan Montgomery takes on Eduardo Rodríguez in a battle of the lefties at Fenway Park. On paper, this looks like a fantastic matchup for the Yankees. With an ERA of 3.55 and a FIP of 3.49, Montgomery has genuinely been one of the best No. 2 starters in baseball this year, ranking 20th in fWAR among starting pitchers who have thrown at least 140 innings with 3.5. Rodríguez, on the other hand, has struggled to keep runs off the board, posting a 4.97 ERA despite a 3.45 FIP, thanks in part to Boston’s terrible defense (their -6 OAA with him on the mound is tied for 272nd in baseball).
