Alex Call (2), Mike Yaztrzemski, Miguel Andujar, and Cedrick Mullins (3) were the examples I found closest to Larnach.
I know Mullins is a CF, which is probably why he returned 3 A+ pitchers even while having a down year, that and he was traded to the Mets, who were evidently willing to overpay.
Willi Castro returned 2 AA pitchers, Chicago was also willing to overpay.
Bader was having a career resurgence, but only returned a AA OF and a young pitcher that was pitching in the Dominican Summer League.
Stewart, the oft-injured RP, returned Outman.
I don't see Larnach bringing back a MLB RP, much less one that will impact the teams BP down the stretch.
