Rays activate RHP Zach Eflin, DFA righty Hector Perez

According to Marc Topkin of the Tampa Bay Times, the Rays have activated right-hander Zach Eflin from the 15-day IL to start Sunday's game against the White Sox. In a corresponding move, the club has designated right-hander Hector Perez for assignment.

Eflin’s return will help fortify a Rays rotation currently wracked with injuries. In addition to Tyler Glasnow having yet to make his debut this season thanks to an oblique strain, breakout left-hander Jeffrey Springs saw his season end last week when it was announced he is set to undergo Tommy John surgery. 

Eflin, who signed a three-year, $40M deal to join the Rays over the offseason, had a 3.27 ERA and 2.63 FIP in two starts before being placed on the 15-day injured list due to back tightness. The ailment clearly proved to be minor, as Eflin is returning after a backdated minimum stay on the IL.

That’s good news for the Rays, who now have another reliable arm in the rotation alongside Shane McClanahan, Drew Rasmussen and prospect Taj Bradley. 

With Bradley and Rasmussen set to pitch the next two days, the Rays will need another starter on Wednesday, though it’s possible they could turn to a bullpen game led by lefty Josh Fleming, who opened the season in the rotation but has since been bumped to the bullpen after struggling in his first start of the season.

As for Perez, the 26-year-old right-hander was just selected on Saturday and did not end up making an appearance during his stint on the roster. Perez has made one appearance in his big league career, a 1 2/3 inning outing with the Blue Jays in 2020 during which he surrendered two runs on three hits and three walks. Perez has long struggled with his control, as evidenced by his career 14.4% walk rate. Those control problems have likely contributed to his struggles to return to a major league mound over the past three seasons. The Rays will now have seven days to trade, waive or release Perez.
