I feel like trying to make this Gasser-Henderson comparison is a bit odd because Henderson has done this for 10 starts now and has done it in a much more sustainable way than Gasser did. He's also a more regarded prospect than Gasser ever was.
Henderson first 10 starts - 2.72 FIP, 3.14 xFIP, 33% K-rate, 7% BB-rate
Gasser before TJ - 3.38 FIP, 4.18 xFIP, 14% K-rate, 1% BB-rate
