Without looking, which one is Robert Stephenson and which one is Tyler Glasnow? I'll leave out the innings so that it's less obvious.
Player A - 22 K, 17 BB, 2HR, 6.97 ERA/4.89 FIP/5.48 xFIP
Player B - 19 K, 12 BB, 3 HR, 9.69 ERA/5.85 FIP/5.15 xFIP
Obviously one is doing it as a starter and the other a reliever, but it doesn't look like either is ready for the show.
