Overall Summary
Big, thick RHP that fits well in late-inning reliever role and can give multiple innings. Has been a closer in the past, but recently moved to the rotation in 2014. Has been up to 96-97 mph before entering the rotation and see him getting back to plus with the fastball in shorter stints. Pounds down in zone and works in to both righties and lefties. Forkball is his out pitch; above-average feel and will work in variations on the depth; bigger tumble early in count and circle change-type bottom for put-away. Slider used almost exclusively to RHH; for strikes. Variations on the curveball; big shape, hump with occasional snap; 4th pitch, likes to use early in count. Showing average command recently, but will have stretches where he loses the plate. Easy mechanics, does not have to be max effort to generate velocity; little bit of a rep. as a "thrower" in past years, but has made some strides with his command in 2016.
