Breslow, 34, will look to bounce back from a rough 2014 in which he worked to a 5.96 ERA over 54 1/3 innings, with 6.1 K/9 against 4.6 BB/9. Though ERA estimators all felt that Breslow was the victim of some bad luck, even the rosiest among them (SIERA, 4.72) saw him as a well-below-average producer. Oddly, he struggled most against same-handed hitters, whom he walked more often than he struck out. Lefties hit Breslow to the tune of .291/.381/.456 last year.
That said, Breslow is not exactly an unknown commodity. He had never before gone over the four-earned-per-nine level in a season, and was fresh off of a 1.81 ERA campaign in 2013. Over his lifetime work, he has been much better against left-handed bats, though in general he posts minimal platoon numbers.
