I’ve mentioned Montero as one of three RPs to target this off-season, along with Michael Fulmer and Blake Treinen (assuming he’s healthy).
A LHRP might be necessary, too, with Davis and Diekman gone, Strahm leaving, Taylor questionable, and Darwinzon just incapable of throwing strikes. But then the 3-batter-minimum rule has really cut into the importance of the LHRP and you need pitchers whose only skill isn’t being left-handed.. or
