Red Sox place two-time Gold Glove winner on injured list

The Red Sox announced they’ve placed Tyler O’Neill on the seven-day concussion injured list, retroactive to April 16. Rob Refsnyder was reinstated from the IL to take the active roster spot.

O’Neill suffered the injury on Monday when he collided with Rafael Devers while tracking a shallow fly ball. O’Neill’s forehead hit the back of Devers’ head. Devers stayed in the game but O’Neill came out. 

While he initially cleared concussion protocol, he hasn’t played in either of the last two games. He’s evidently still not ready to return and will be out for at least another five days. MassLive’s Christopher Smith tweets that O’Neill was diagnosed with a mild concussion.

Acquired in something of a buy-low offseason trade, O’Neill has been off to a scorching start to his Red Sox tenure. He’s hitting .313/.459/.750 and is third in the majors with seven homers. O’Neill showed impact ability intermittently throughout his time with the Cardinals, but he’d produced at a roughly league average level from 2022-23. He’ll be a free agent for the first time at the end of this season.

In other injury news, manager Alex Cora said the Sox are sending Devers for an MRI on his left knee, via  Sean McAdam of MassLive. The two-time All-Star has played through some discomfort in the joint in recent days, although there’s nothing to suggest it’s related to Monday’s collision. He was the designated hitter Wednesday but is out of the lineup for Thursday’s contest with the Guardians.

It seems the current round of imaging is mostly precautionary. The Sox surely want to rule out any possibility that Devers is playing through some kind of structural issue that would necessitate a shutdown. He’s still day-to-day pending the MRI results.

Devers has gotten off to a slow start. He’s hitting only .188 through his first 13 games. A massive 15.5% walk rate has kept his on-base percentage at a respectable level, but Devers clearly hasn’t found his typical form. His hard contact percentage has been well below his normal level. It’s likely that playing through discomfort — he also battled shoulder soreness around Opening Day — has contributed to the slump. Assuming there’s nothing significantly wrong with his knee, Devers shouldn’t have much issue recapturing his groove offensively.

There’s nevertheless added uncertainty to an already shaky Boston infield. Devers and Triston Casas flank a much less imposing middle infield group. Injuries to Vaughn Grissom and Trevor Story have pushed the likes of Enmanuel Valdez, Pablo Reyes and David Hamilton into meaningful roles. Story is out for the season, so shortstop will remain a question all year unless the Sox go outside the organization.

Grissom, who started the year on the shelf with a hamstring strain, will take over second base within two weeks. He began a minor league rehab assignment last Friday, opening a 20-day window for his activation to the MLB roster. Cora said Thursday that the Sox aren’t likely to reinstate Grissom before their forthcoming week-long road trip, via The Athletic’s Jen McCaffrey. Grissom didn’t get any game action in March, so he’s using the rehab period as something of an abbreviated spring training.
