Quick Mitch Keller thread:
Keller didn& #39;t really throw anything but his his fastball and slider in the first two innings but started throwing the hook more in innings three, four and five
Keller didn& #39;t really throw anything but his his fastball and slider in the first two innings but started throwing the hook more in innings three, four and five
He has a fastball in the 83rd percentile in velo and 85th percentile in spin. He should be throwing it up in the zone more. It was a 60 by FanGraphs every year until this year, where it is now a 55
His curveball was also always a 60 before this year. He& #39;s in the 85th percentile for spin, but only has 54% spin efficiency per Dr. Nathan& #39;s calculator. He gets good spin, but not as much movement. 17 whiffs/50 swings for a rate of 34%, about the 32.44% league average
His slider, which FanGraphs calls a 60, is also in the 85th percentile in spin. It has low spin efficiency (9.21%) but that& #39;s good for a slider. High spin, low efficiency means low vertical movement but more horizontal movement, as seen below
The slider got 43 whiffs on 90 swings, a rate of 47.78% compared to the league average of 36.16% (among pitchers >= 100 sliders). The pitch is good. The stuff is there to succeed
87.9 mph slider to strike Contreras out. It& #39;s good stuff and Keller did produce a 28.6% strikeout rate and 11.8% swinging strike rate, both above average
