The Mets don’t know what is going on with Sean Reid-Foley, whose rehab assignment has been stalled.
The righty reliever, who is making his way back from a right shoulder impingement that has sidelined him since June 19, has struggled in six minor league games in which he has walked eight in 4 ²/₃ innings.
Reid-Foley most recently pitched Tuesday with Triple-A Syracuse and allowed two hits, a walk and two runs in 1 ¹/₃ innings.
Manager Carlos Mendoza said Reid-Foley likely won’t throw in a game again “in the next few days.”
“One of those [situations] where he’s not sure if it’s mechanics or what, but the ball’s not coming out the way he would like it to,” Mendoza said before the Mets played the A’s at Citi Field on Wednesday. “So we got to figure out what we’re dealing here with.”
Reid-Foley feels fine physically, Mendoza added, though his velocity has not fully returned.
Reid-Foley, whose four-seamer averaged 94.9 mph in 23 games this season, was throwing 92-93 mph on Tuesday, Mendoza said.
The Mets had not yet formally shut down his rehab assignment, which would buy them more time.
Pitchers are allowed 30 days to rehab before they must be activated, optioned or otherwise moved, which would mean the Mets would have to make a decision on Reid-Foley before Aug. 27 under the current clock.
Reid-Foley can no longer be optioned to the minors.
Reid-Foley, a 28-year-old who has been with the Mets since 2021, was having his best season before his shoulder bothered him.
In 23 games, he owns a 1.66 ERA and 25 strikeouts in 21 ²/₃ innings.
J.D. Martinez, who left Tuesday’s loss after a 99.6-mph fastball drilled his left elbow, was back in the lineup a day later.
Mendoza said he did not anticipate Martinez being ready yet, but the DH told him that he was feeling well.
Martinez wore a new elbow pad during his pregame batting practice.
Dedniel Nunez (right pronator strain) looked “really good” in his Tuesday bullpen session, Mendoza said, and was up to 94 mph.
The righty will throw another bullpen session or live batting practice Friday.
Top prospect Brandon Sproat was ejected from his second start with Triple-A Syracuse arguing a play at the plate.
Sproat allowed one run on two hits and two walks in three innings in which he struck out two.
