Goes on 60-day IL with UCL tear The Mariners placed Kowar on the 60-day injured list Sunday after he was recently diagnosed with a torn UCL in his right elbow.
Impact After experiencing arm soreness early last week, Kowar was sent in for tests Friday, at which point the UCL damage was detected. The Mariners haven't officially commented on Kowar's next steps, but he'll most likely undergo Tommy John surgery or an internal brace surgery, which would keep him sidelined throughout the 2025 season. Kowar , whom Seattle acquired from Atlanta in December, was expected to handle a low-leverage role out of the Mariners bullpen.

Pushed back due to soreness Kowar's next Cactus League appearance will be pushed back a few days as he deals with soreness, Ryan Divish of The Seattle Times reports.
Impact Where exactly the soreness is located is not clear, but it doesn't seem like the Mariners have much concern that this could be a long-term injury. Kowar has impressed in the early going this spring with three strikeouts over two scoreless frames.
MARCH 5 • ROTOWIRE
Picks up second win Kowar (2-0) allowed a hit and struck out two over a scoreless inning to earn the win Monday over the Guardians.
Impact Kowar's two wins have come over his last five appearances, in which he's posted a 5.1-inning scoreless streak with a 6:1 K:BB. The right-hander is finding a bit more success out of the bullpen in the majors, though he still has a 4.91 ERA, 1.68 WHIP and 28:16 K:BB through 25.2 innings over 20 appearances this season. Kowar started just one of his 30 outings with Triple-A Omaha but pitched to a 5.96 ERA over 45.1 innings. It appears he'll mostly remain in a low-leverage role with the capability to take multiple innings for the rest of this season.
SEPTEMBER 19, 2023 • ROTOWIRE
Snags first major-league win Kowar (1-0) struck out one in a perfect inning to earn the win Tuesday over the White Sox.
Impact Kowar pitched the ninth inning with the Royals down by one, but they scraped together two runs to walk it off. This was Kowar's fifth scoreless effort across eight appearances since he was recalled from Triple-A Omaha on Aug. 17. The right-hander has a 5.91 ERA, 1.83 WHIP and 23:15 K:BB over 21.1 innings in the majors this season while working almost exclusively as a reliever across all levels.
SEPTEMBER 6, 2023 • ROTOWIRE
Recalled from Omaha Kansas City recalled Kowar from Triple-A Omaha on Thursday.
Impact Kowar returns to the Royals as a fresh bullpen arm ahead of Thursday's series finale against the Mariners. The 26-year-old right-hander has allowed 12 runs -- eight earned -- in 11.2 innings of work this season at the MLB level.
AUGUST 17, 2023 • ROTOWIRE
Sent back to Omaha Kansas City optioned Kowar to Triple-A Omaha on Wednesday.
Impact James McArthur has also been sent to Omaha, with Cole Ragans and Tucker Davidson joining the Royals ahead of Wednesday night's game against the Mets. Kowar, 26, did not make an appearance during his one-day stint on the major-league roster.
AUGUST 2, 2023 • ROTOWIRE
Promoted to KC The Royals recalled Kowar from Triple-A Omaha on Tuesday, Anne Rogers of MLB.com reports.
Impact Kowar and James McArthur will both come up from the minors to make up for the loss of Scott Barlow and Ryan Yarbrough following Tuesday's trade deadline. With a 9.83 ERA and 2.13 WHIP through 57.2 career MLB innings, Kowar offers very little fantasy value.
AUGUST 2, 2023 • ROTOWIRE
Back to minors Kowar was optioned to Triple-A Omaha on Saturday.
Impact Kowar was most recently promoted to the majors June 2, and he pitched 9.1 innings across seven appearances since. He allowed at least one run on four occasions, which amounted to a 7.71 ERA.
JUNE 24, 2023 • ROTOWIRE
Recalled from Triple-A Kansas City recalled Kowar from Triple-A Omaha on Friday.
Impact The 26-year-old right-hander will replace Amir Garrett, who is headed to the 15-day injured list with a left elbow injury. A former top prospect, Kowar projects to operate in long relief as he joins the Royals' major-league roster for the second time this season.
JUNE 2, 2023 • ROTOWIRE
Sent back to Omaha Kowar was optioned to Triple-A Omaha on Saturday.
Impact Kowar was called up on Tuesday and tossed 2.1 scoreless innings while walking two batters and striking out three others in Friday's 2-0 loss to the White Sox. With Amir Garrett (personal) being reinstated from the family emergency list Saturday, Kowar will head back to Triple-A. The right-hander could earn another call up later this summer if a bullpen arm goes down for Kansas City.
MAY 20, 2023 • ROTOWIRE
Former first-round pick Jackson Kowar is back with the Royals, this time as a reliever. The Kansas City Royals will evaluate 2018 draft pick Jackson Kowar in a new role out of the bullpen.

Recalled from Triple-A The Royals recalled Kowar from Triple-A Omaha on Tuesday.
Impact Kowar holds a 7.84 ERA and 2.13 WHIP through 20.2 innings across 13 appearances in Omaha this season. His struggles are nothing new, as he hasn't maintained an ERA below 6.00 at any level since 2021. He has a knack for striking batters out at an above-average rate, but Kowar still holds virtually no fantasy value. Max Castillo was optioned to Omaha in a corresponding move.

Role is undecided Kowar's role moving forward has yet to be determined by the Royals, Anne Rogers of MLB.com reports.
Impact Kowar was part of the Royals' camp cuts Wednesday and the team is still deciding whether to deploy him as a starter or reliever. The first-round pick will stay stretched out this spring, but it's possible the organization ultimately determines his best bet to help down the line is as a reliever. Kowar, 26, has struggled in both roles in the majors so far with a 9.16 ERA as a reliever and an even-uglier 11.85 mark as a starter.
MARCH 15, 2023 • ROTOWIRE
Optioned out to Triple-A The Royals optioned Kowar to Triple-A Omaha on Wednesday.
Impact Kowar had surrendered five earned runs on seven hits and three walks through five innings of work this spring in the Cactus League. The 26-year-old carries a ghastly 10.76 ERA in 46 career frames at the MLB level.

Aaron Judge became the second-fastest player in major league history to reach 200 career home runs, and the New York Yankees beat the Kansas City Royals 8-2JULY 30, 2022 • ASSOCIATED PRESS
Optioned to Triple-A Kowar was optioned to Triple-A Omaha on Saturday.
Impact Kowar was called up Wednesday, and he gave up two runs on two hits and two walks while failing to strike out a batter in one-third of an inning during Friday's game against the Yankees. He'll head back to the minors after Jonathan Heasley (shoulder) was reinstated from the 15-day injured list.

Called up Wednesday Kowar was called up from Triple-A Omaha on Wednesday.
Impact Kowar will return to the Royals just one day after being sent down to Omaha. He'll replace Angel Zerpa (knee) on the active roster after the latter was placed on the 15-day injured list Wednesday. Kowar has produced a 8.80 ERA over 15.1 innings in six appearances with Kansas City this year.
JULY 27, 2022 • ROTOWIRE
Heads to Omaha The Royals optioned Kowar to Triple-A Omaha on Tuesday, Joel Goldberg of Bally Sports Kansas City reports.
Impact Kowar threw two scoreless innings in his most recent appearance July 14, yet he still has an 8.80 ERA through six games this season. The righty figures to rejoin Kansas City for bullpen depth at some point in 2022.

Struggles in long relief Kowar allowed five runs on seven hits and three walks while striking out three over 2.2 innings during Saturday's 13-1 loss to the Guardians.
Impact Jonathan Heasley was blitzed in the first two innings, and Kowar didn't do much better, though he recorded the most outs of any Royals pitcher in the contest. With eight runs, 12 hits and eight walks in 10 innings across four appearances since his June 26 recall from Triple-A Omaha, Kowar hasn't looked very effective against major-league hitters. Daniel Lynch (finger) is expected to return from the injured list Monday, and it figures one of Heasley, Kowar or Kris Bubic is most likely to be headed back to Omaha to make room for him.
