Doctors recommended the surgery in March but Dominguez was stuck at his home in the Dominican Republic due to the ongoing coronavirus pandemic. The hard-throwing right-hander was able to return to the team Thursday and is now expected to undergo the surgery as early as this month in Florida.
Dominguez hasn't pitched in a regular-season game since June 5 due to an injured ulnar collateral ligament. The reliever previously tried to rest and rehabilitate the injury without surgery, pitching two perfect innings this spring with a pair of strikeouts.
The 25-year-old had a breakout debut campaign in 2018, authoring a 2.95 ERA and 2.85 FIP over 58 innings while collecting 16 saves for the Phillies.
