Gunnar Henderson Diagnosed With Intercostal Strain

Orioles shortstop Gunnar Henderson has been diagnosed with a mild right intercostal strain. Manager Brandon Hyde relayed the information to reporters today, including Jake Rill of MLB.com. Hyde says the club is still “very, very hopeful” of Henderson being on the Opening Day roster, which is now just over three weeks away.

Henderson was removed from a Grapefruit League game against the Blue Jays last week, with the O’s announcing that he had lower right side discomfort. After that contest, Hyde downplayed the concern, framing the removal as precautionary and saying that Henderson would not even require an MRI.

A week later, it seems the issue has lingered enough that his readiness for Opening Day is a question mark. Though Hyde still thinks Henderson could be ready by the opener, he also suggests they won’t be aggressive with him just for that one game. “I’m very, very hopeful,” Hyde said today, per Rill. “But we’re going to not push a strain there, and we want to make sure that he gets it taken care of. It’s one of those sensitive areas where we don’t want anything to reoccur.”

Whether Henderson is in the lineup on Opening Day or not, it’s a situation worth monitoring, given his importance to the team. Henderson won American League Rookie of the Year honors in 2023 and vaulted to a new level last year. He hit 37 home runs, stole 21 bases, slashed .281/.364/.529 and got strong grades for his shortstop defense. FanGraphs credited him with 8.0 wins above replacement on the year. That would have been good enough for an MVP award in many years but Henderson finished fourth in the voting, thanks to outrageous seasons from Aaron Judge, Bobby Witt Jr. and Juan Soto.

The O’s will likely have to consider some contingency plans, even if they ultimately expect Henderson to get healthy in the next three weeks. Jorge Mateo played a lot of shortstop before Henderson took over that spot but he’s currently recovering from elbow surgery and likely to start the season on the injured list. Jackson Holliday has shortstop experience but the club has largely moved him to second base.

Jordan Westburg has plenty of shortstop experience in the minors but just ten big league innings there. He has his own health situation since he’s been dealing with back soreness/spasms this spring. He hasn’t played in a while but Hyde said to Rill it’s possible he could play in Thursday’s game, depending on how he feels in the morning. If Westburg were to cover short, it would create a hole a third, which could be filled by Coby Mayo or Ramón Urías. The O’s also have a few infielders in camp as non-roster invitees, such as Terrin Vavra, Liván Soto, Luis Vázquez, Emmanuel Rivera and Vimael Machín.

There are many moving parts and the situation will surely change in the coming weeks before Opening Day. Ideally, Henderson will just be back in action and everything would be back in its proper place, though Baltimore fans will likely be keeping a keen eye on developments between now and then.

Elsewhere on the roster, reliever Andrew Kittredge has some left knee soreness. Hyde tells reporters, including Andy Kostka of The Baltimore Banner, that he’s undergone an MRI and will seek multiple opinions. The O’s signed Kittredge to a one-year, $10MM deal in January to bolster their bullpen. He posted a 2.48 earned run average over the 2021 to 2024 seasons. Tommy John surgery wiped out most of the middle two seasons of that span but he tossed 70 2/3 innings last year with a 2.80 ERA, 23.3% strikeout rate, 7% walk rate and 45.2% ground ball rate.
