What a difference a year makes. Last year around this time Dellin Betances was persona non grata, essentially unusable in the postseason because his control had deteriorated down the stretch. The Yankees had to cover 8.2 innings with their bullpen in the 2017 Wild Card Game and Betances never even warmed up. Chasen Shreve warmed up. Betances did not.
This season, after an offseason of trade (and even non-tender) speculation, Betances reemerged as a dominant bullpen arm, throwing 66.2 innings with a 2.70 ERA (2.47 FIP) during the regular season. His 42.3% strikeout rate was a career high.
