OUT

Out · expected back around Feb 1

The right-hander headed for a second opinion on his strained right forearm last week and is now set to go under the knife. The full scope of the procedure isn't clear, but if it's standard Tommy John surgery, Kolek will miss the rest of the season and will likely be sidelined for the entirety of the 2027 campaign.

Latest news

  • Manager Matt Quatraro announced that Kolek is scheduled to undergo Tommy John surgery on his right elbow Wednesday, Joel Goldberg of Bally Sports Kansas City reports.

    The right-hander headed for a second opinion on his strained right forearm last week and is now set to go under the knife. The full scope of the procedure isn't clear, but if it's standard Tommy John surgery, Kolek will miss the rest of the season and will likely be sidelined for the entirety of the 2027 campaign. In 10 starts for the Royals this year, he posted a 4.50 ERA, 1.24 WHIP and 34:12 K:BB across 54 innings.

  • Kolek will get a second opinion on his right forearm Tuesday, Jaylon T. Thompson of The Kansas City Star reports.

    Kolek emerged out of his rehab start with Triple-A Omaha on July 18 with a right forearm strain, which prompted the Royals to transfer the right-hander to the 60-day injured list July 22. He's eligible to be activated from the IL in early September, but the Royals will have a better sense of Kolek's recovery timeline once he undergoes more tests.

  • The Royals transferred Kolek (forearm) from the 15-day injured list to the 60-day IL on Wednesday.

    Kolek made his most recent appearance for the Royals on July 2 before landing on the family medical emergency list a couple of days later. The right-hander was able to make a rehab start at Triple-A Omaha on Saturday, but he emerged from that outing with a right forearm strain and was moved to the Royals' 15-day injured list. Though Kolek remains without a clear timeline for a return while he weighs his treatment options for the injury, the Royals' decision to shift him to the 60-day injured list will keep him out until at least September. The transaction opens up a spot on the 40-man roster for infielder Andrew Velazquez, whose contract was selected from Triple-A.

  • The Royals reinstated Kolek (personal) from the family medical leave list and placed on the 15-day injured list Sunday due to a right flexor strain.

    The right-hander has spent most of the past few weeks on the paternity and family medical emergency list, and he appeared close to rejoining the Royals when he began a rehab assignment Saturday. Kolek presumably sustained the injury in his start with Triple-A Omaha, during which he surrendered two earned runs on six hits with a 3:0 K:BB over 2.2 innings. The Royals haven't provided a timeline for the 29-year-old to return from the forearm injury.

  • Kolek (personal) will make a rehab start Saturday, Anne Rogers of MLB.com reports.

    Kolek has been on the Family Medical Emergency List since early July. Saturday's rehab outing will likely be his only one, and he could return to the Royals for their next series against the Giants that starts Monday. Kolek went 4-3 across 10 starts in the first half of the regular season, posting a 4.50 ERA, 1.24 WHIP and 34:12 K:BB across 54 innings.

  • The Royals placed Kolek (personal) on the Family Medical Emergency List on Saturday.

    Kolek's next start is tentatively slated for next week on the road against the Mets, though it's unclear whether he'll be with the team at that time. He took the loss in his last start against the Rays on Thursday, when he allowed three runs on four hits and one walk across two innings without recording a strikeout. Prior to that outing, Kolek spent some time on the paternity list and then the family medical emergency list before rejoining the team Thursday. The Royals recalled right-hander Jose Cuas from Triple-A Omaha in a corresponding move.
