Duffey has a 2.10 ERA and 0.94 WHIP over 25.2 innings this season.
The 26-year-old started 36 games for the Twins over the last two years but is finding success this season in a bullpen role. Duffey's low WHIP is the result of his stellar BB/9 of 1.8 and opposing batting average of .202. The right-hander will often pitch multiple innings but has yet to see many high-leverage situations.
