The Orioles traded left-hander Gregory Soto to the New York Mets on Friday, a source confirmed, as part of what is expected to be a trade deadline sell-off over the final week of July.

Baltimore acquired Soto ahead of last year’s trade deadline from the Philadelphia Phillies.

Soto picked up the save for the Orioles in Thursday’s win against the Cleveland Guardians. The 30-year-old holds a 3.96 ERA in 36 1/3 innings. His velocity, which touches triple digits, makes him a strong swing-and-miss candidate. But he can also struggle with command, as he did in Monday’s outing, in which he allowed three walks and two runs.

SNY first reported that Soto was headed to the Mets. The Orioles will receive right-handers Wellington Aracena and Cameron Foster, the source said.

Aracena, 20, is a Single-A prospect who ranked No. 28 in the Mets’ farm system, according to Baseball America. Foster, 26, was in Double-A.

On Thursday, when asked about the possibility of a trade, Soto said through team interpreter Brandon Quinones: “I can’t control that. What I can control is going out there, doing what I did today, doing my job. If they ultimately decide to make a decision where they trade me, perfect, let it be.”

Last year, Soto arrived from the Phillies along with right-hander Seranthony Domínguez, although they were acquired in separate deals. In the Camden Yards clubhouse Friday, Domínguez said he understands that trades are “part of the business.”

“I wish him the best and good luck to him,” Domínguez said. While Domínguez realizes he could also be traded again, “I don’t try to think about it,” he said.

“Just try to go one step at a time,” Domínguez said. “I’m here today, and I’ll try to do my best to help the team win.”

Soto is the second reliever Baltimore has dealt this month, with right-hander Bryan Baker having been traded to the Tampa Bay Rays. The return for Baker, a competitive balance round-A pick, turned into outfielder Slater de Brun, whom Baltimore signed Thursday with an over-slot $4 million bonus.

Aracena drew praise from Baseball America for his high velocity. His fastball averages 97 mph and can touch 101. He started occasionally for the St. Lucie Mets but also was used in a hybrid role, covering multiple innings as a reliever. Baseball America projects Aracena as a future reliever.

He is considered the prize of the trade. According to Prospect Savant, opponents’ expected batting average against him in Single-A is .167. He’s striking out batters at a 33.5% rate (82nd percentile), and his whiff rate of 37.4% is in the 86th percentile.

Foster was recently demoted from Triple-A (a 17.18 ERA in two games) to Double-A (1.01 ERA in 19 relief appearances). He was not ranked in New York’s top 30 prospect list.

The Orioles could be active at the deadline, with relievers Domínguez and Andrew Kittredge also candidates to move.

Three starters (Charlie Morton, Zach Eflin and Tomoyuki Sugano) are considerations, as well. And first baseman Ryan O’Hearn and outfielders Ramón Laureano and Cedric Mullins are likely to draw interest.
