The Phillies recalled Romero from Triple-A Lehigh Valley on Sunday.
Romero will provide the Phillies with another fresh arm out of the bullpen after Archie Bradley (oblique) was placed on the injured list in a corresponding move. Over his 12 appearances out of the Philadelphia bullpen as a rookie in 2020, Romero gave up nine earned runs on 13 hits and two walks in 10.2 innings.
