The Mets made a move for a fresh arm prior to Tuesday's contest in San Diego.
Right-hander Huascar Brazoban was optioned to Triple-A after his shaky outing in Monday's game.
Brazoban came on in relief of the struggling Frankie Montas in the bottom of the fifth, and he appeared to dance his way out of a second and third one out jam, but was late covering first on a grounder to Pete Alonso.
The floodgates opened from there, as the Padres' eight and nine hitters rattled off back-to-back singles to bring in the tying and go-ahead runs at the time.
San Diego, of course, walked things off a few innings later.
This continues what's been an up-and-down stretch for Brazoban, who was spectacular at the beginning of the year but allowed 14 runs (13 earned) across just nine outings in June.
He's up to a 3.83 ERA and 1.28 WHIP over 51.2 innings of work this season.
In a corresponding roster move, the Mets brought back Chris Devenski on a one-year big league deal and added him to the active roster.
Devenski was designated for assignment just a week ago as the Mets made a flurry of moves, including bringing hard-throwing right-hander Rico Garcia up to the major league roster.
After clearing waivers, the 34-year-old opted to elect free agency rather an accept an outright assignment to Triple-A, but now he landed back in the Big Apple.
He pitched well before being let go, posting a 2.38 ERA and 0.88 WHIP across 10 appearances.
