Espinoza was recalled from Triple-A Iowa on Saturday, Tim Stebbins of NBC Sports Chicago reports.
EDGE Analysis
He was optioned down a few days ago, but he didn't make an appearance during his brief stint in Iowa. Espinoza has a 4.11 ERA, 1.50 WHIP and 15:13 K:BB in 15.1 innings across six appearances. He should work in long relief after taking the place of Keegan Thompson (back) on the active roster.
