Dominic Leone: -0.1 fWAR, -0.4 bWAR
A former rookie-of-the year candidate with the Seattle Mariners, Dominic Leone posted an incredible-for-a-reliever 2.1 rWAR in 65 appearances for the Toronto Blue Jays in 2017. But for two-straight injury-plagued years with the Cardinals, Leone has returned to that negative WAR territory that plagued his sophomore and junior seasons.
After Leone struggled to an 8.02 ERA with a 27:11 K:BB over 21.1 innings this season, the portly 27-year old was banished earlier in the year to Memphis. Many expected him to never return. But he battled back to the big leagues.
After being recalled to St. Louis on June 25, he has pitched better, though inconsistent, and not enough to pull himself out of negative-WAR hell.
Barring a major uptick in the last two weeks for Leone (and he could in fact see some work with the current beleaguered state of the bullpen) he certainly will not be on the playoff roster, and may indeed be packing his bags for a new destination in 2020.
