In his career, Dustin Moseley is 5-4 with a 5.69 ERA as a starting pitcher. That covers 23 games and 110 innings (4.78 innings per start). He’s 3-3 with a 4.76 ERA in 45 relief appearances (68 innings).
In the past he’s relied mostly on an upper-80s fastball, curve and changeup, however, this year with the Yankees he’s cut down on the fastball some while working in a new slider. He threw a slider with the Angels last year, but this one seems pretty different. The Angels version came in around 78 mph. This slider is around 86 mph. You have to wonder if it might not just be a cutter that has a lot of break.
Moseley has about equal splits against right-handed hitters (.312) as against lefties (.296), so he shouldn’t be too affected by a lineup slanted either way.
His best year was with the Angels in 2007 when he went 4-3 (46 games, eight starts) with a 4.40 ERA.
