Dominguez was recalled by the Phillies on Saturday, Scott Lauber of The Philadelphia Inquirer reports.
Dominguez was an effective reliever in 2018 and the first half of 2019, saving 16 games while riding a 30.2 percent strikeout rate and 55.3 percent groundball rate to a 3.27 ERA. He then developed elbow problems which eventually required Tommy John surgery, but he's set to return to big-league action just shy of 28 months since his last appearance at the highest level. He hasn't been good in 20.1 innings in the minors this season as he works his way back to full strength, struggling to a 7.97 ERA, though he hasn't allowed an earned run in any of his last five trips to the mound. Connor Brogdon (groin) hit the injured list to clear space on the roster.
