The Dodgers announced this afternoon that they’ve selected the contract of left-handerNick Ramirez. LeftyJustin Wrobleski was optioned to Triple-A in a corresponding move, and right-handerMichael Petersen was designated for assignment to make room for Ramirez on the 40-man roster.

Ramirez, 35, was acquired by the Dodgers in atrade with the Yankees back in April after the southpaw failed to make the Opening Day roster in the Bronx. A fourth-round pick by the Brewers back in 2011, Ramirez didn’t make his big league debut until 2019 as a member of the Tigers. He posted middling results in relief across three seasons with Detroit and San Diego from 2019-21, with a 4.55 ERA (101 ERA+) and 4.60 FIP in 110 2/3 innings of work while striking out 20.4% of opponents.

The lefty signed with the Mariners on a minor league deal headed into the 2022 season and posted impressive results at the Triple-A level, with a 2.93 ERA and a 23.7% strikeout rate in 55 1/3 frames, but was unable to crack the club’s big league roster. That led him to sign with the Yankees on a fresh minors pact for the 2023 season, and he enjoyed the best season of his career in the Bronx as he posted a fantastic 2.66 ERA and 2.94 FIP in 40 2/3 frames after being selected to the Cubs roster in late April, after which point he was shuttled between the majors and minors on a semi-frequent basis.

Unfortunately, Ramirez has not been able to replicate that same success with the Dodgers. He’s pitched 11 1/3 innings in the majors this year but has struggled to a 6.35 ERA with a 4.33 FIP and just four strikeouts. That lackluster production has carried over to his performance at Triple-A Oklahoma City, for whom he’s pitched to a 4.65 ERA in 31 innings of work this year with a lackluster 19.2% strikeout rate. The Dodgers are surely hoping he can improve upon that performance in his latest stint with the club, though he’s buried on the relief depth chart by bothAlex Vesia andAnthony Banda in terms of left-handed options, likely leaving him to be used in exclusively low-leverage situations while with the club.

Ramirez takes the spot of Petersen on the 40-man roster. The righty got his first taste of big league action back in June when he was selected to the roster in the aftermath ofYoshinobu Yamamoto’s placement on the injured list due to a rotator cuff strain. The right-hander has served as an up-and-down bullpen arm for the Dodgers in the months since then, though his results have left much to be desired. In 14 innings of work across 11 appearances, Petersen has struggled to a 6.43 ERA with a 6.32 FIP in the majors, though he’s been nothing short of dominant at Triple-A with a sparkling 1.64 ERA and a 35.2% strikeout rate in 33 frames. If Petersen goes unclaimed on waivers, the Dodgers will have the opportunity to outright the right-hander to Triple-A where he can act as non-roster depth for the club down the stretch.
