Rafael Devers will get an MRI on his knee, Alex Cora announced Thursday morning.

“He didn’t feel great yesterday, he felt like he wasn’t able to stay on his leg,” the Red Sox manager said. “I talked to him last night, I said ‘Well, let’s do this so we know.’ Hopefully, it’s what we think it is and we deal with it, and (he) gets treatment, all that stuff, but I think it’s more for him to (have) peace of mind.”

The third baseman went 0-for-4 with three strikeouts in Wednesday’s 2-0 victory over the Cleveland Guardians. He only played in five of the 10 games during the first homestand, and went 2-for-16 (.125) with four walks and five strikeouts. Through 13 games overall, he’s hit .188/.328/.375 with nine hits, three doubles, two home runs, five runs and five RBI, nine walks, and 10 strikeouts.

“He played because he wanted to play,” said Cora. “Just, he wasn’t able to stay on his back leg yesterday, he was out in front. He got a fastball, I think with men on second and third, he got two fastballs that he didn’t catch up with in a spot that he usually does. Mechanic-wise, he was off.”

Devers’ health has been a roller coaster throughout the start of the season. He missed multiple games during the opening series in Seattle as well earlier in the homestand due to nagging shoulder soreness.

“He’s okay” in that regard, Cora said. “He actually felt like the night before, he took better swings.”

“He’s frustrated with the fact that he was feeling so good during spring training and the swing was on point, he made some changes and he was working, and all of a sudden, the shoulder and this knee thing,” the Sox skipper continued. “Been healthy throughout his career, right?”

Cora can’t rule out Devers joining an already-crowded injured list. “If that’s the case, that’s the case,” he said.

Nick Pivetta (mild elbow flexor strain) will throw his next bullpen on Saturday. “He’s doing good,” Cora said. “He feels he turned a corner. He’s gonna be okay.”

He also said “there’s a good chance” Rob Refsnyder could rejoin the Red Sox on their upcoming road trip to Pittsburgh and Cleveland.

Vaughn Grissom won’t. His rehab assignment with Triple-A continues; he’ll play second base for the WooSox Thursday and Friday.

Romy Gonzalez’s MRI came back clean. “Now it’s about tolerating the pain or whatever he has going on and keep getting treatment, but as far as structurally, he’s good,” Cora said.
