Update (9:55 PM ET): Dominguez made his major league debut in the eighth inning of Monday night’s game against the Giants with the Phillies leading 10-0. He worked a 1-2-3 inning, getting a pair of foul pop-outs and a strikeout.
Dominguez, 23, started the season with Double-A Reading but was promoted to Triple-A near the end of April. In 16 2/3 combined innings with Reading (13) and Lehigh Valley (3 2/3), Dominguez owns a 1.62 ERA with a 21/3 K/BB ratio. According to MLB Pipeline, Dominguez is the No. 11 prospect in the Phillies’ system.
Manager Gabe Kapler says he would be comfortable using Dominguez in a high-leverage situation on Monday, Ben Harris of The Athletic reports.
While the Phillies’ bullpen has overall been decent this year — its aggregate 3.12 ERA is fifth-best in baseball — closer Hector Neris has struggled, walking nine batters in 13 innings on the year. He walked two and gave up two hits in blowing the save during Sunday’s 5-4 walk-off loss to the Nationals.
