How to Project High HR/FB% Pitchers
For the second week in a row, I had to voice my amazement that JT Brubaker was cut in the NFBC Main Event. While Brubaker’s results have not been great (4.95 ERA), there are several signs that point to him being closer to a 4.00 ERA pitcher. The stat that sticks out is his 1.9 HR/9. The home runs have him with a 4.98 FIP while his xFIP is a full run lower at 3.98. I wanted to see if I should blindly assume that his home run rate will drop. With the expected drop, will his FIP and ERA regress downward to his xFIP? Also, are there any measurable traits that make a pitcher more home run prone? I ended up with a “maybe” and a solid “no”.
Brubaker isn’t the only pitcher who fits this mold. Bailey Ober has a 2.2 HR/9. His 4.99 ERA is almost identical to his 5.18 while his xFIP is down at 4.12. Another is Yusei Kikuchi (1.6 HR/9, 4.37 FIP, 3.47 xFIP). Adbert Alzolay (2.0 HR/9, 5.03 FIP, 3.89 xFIP). The season is over halfway over and fantasy managers are losing patience.
