1.8 HR/9

Matthew Liberatore has allowed 14 home runs in 70.1 innings this season — 1.8 per nine, against a league rate near 1.25. His ERA is 5.74. ERA is the number everyone quotes and it is the wrong one for a home run market: a low-ERA fly-ball pitcher gives up more homers than a higher-ERA groundballer, and ERA cannot tell them apart.
