Chafin picked up the save against the White Sox on Thursday after tossing a scoreless inning while allowing one hit.
Chafin worked around a two-out double by Romy Gonzalez to finish off a close lead for the A's. The left-hander didn't induce any strikeouts, but he did throw 10 of his 13 pitches for strikes. The save was just the third of the year for Chafin, who is seeing more ninth-inning opportunities of late given Lou Trivino's recent struggles. Chafin has an excellent 0.86 ERA and 0.76 WHIP across 21 innings since his trade from the Cubs.
