Rotowire
The Mariners recalled Kowar from Triple-A Tacoma on Friday.
Kowar was optioned to Triple-A on Wednesday, but he'll turn around and head back to Seattle to replace the injured Trent Thornton (Achilles). Kowar will likely take on a middle-relief role with the Mariners after posting a 1.54 ERA and 0.86 WHIP through 11.2 innings with the big club this season.

Mariners' Jackson Kowar: Sent back to Tacoma
Rotowire
The Mariners optioned Kowar to Triple-A Tacoma on Wednesday.
The Mariners had to make room in their bullpen after acquiring Caleb Ferguson from Pittsburgh on Wednesday, and Kowar will officially end up as the roster casualty. The 28-year-old righty pitched three scoreless innings after being recalled from Triple-A on Thursday, lowering his big-league ERA to 1.54 through 11.2 frames this season.

Mariners' Jackson Kowar: Back with M's
Rotowire
The Mariners recalled Kowar from Triple-A Tacoma on Thursday.
Since being optioned to Triple-A in mid-June, Kowar has given up six runs (three earned) over nine innings while striking out 12 batters and walking seven. He owns a 2.08 ERA through 8.2 frames with the Mariners this year, but his career 8.38 ERA will keep him limited to a low-leverage role in Seattle's bullpen. Brandyn Garcia was optioned to Tacoma in a corresponding move.

Mariners' Jackson Kowar: Heading to Triple-A
Rotowire
The Mariners optioned Kowar to Triple-A Tacoma on Monday, Shannon Drayer of SeattleSports.com reports.
The transaction frees a spot on the active roster for the return of right-hander Logan Gilbert (elbow) from the injured list. Kowar made seven appearances after being activated from the 60-day injured list late last month, yielding two runs with an 8:3 K:BB over 8.2 frames.

Rotowire
The Mariners reinstated Kowar (elbow) from the 60-day injured list Wednesday.
Kowar will return to the majors after missing the entire 2024 season following Tommy John surgery last March. The 28-year-old right hander posted a 2.57 ERA and 1.29 WHIP across seven innings during his rehab assignment and did not yield a run in each of his last three outings.

Mariners' Jackson Kowar: Closing in on return
Rotowire
Kowar (elbow) could be nearing his activation from the 60-day injured list, MLB.com reports.
Kowar has produced solid results in the minor leagues amidst his recovery from 2024 Tommy John surgery, posting a 2.57 ERA, 1.29 WHIP and 4:3 K:BB over seven innings (eight appearances) on his rehab assignment. The 28-year-old right-hander should be ready to make both his Mariners and season debut by early June, and he'll likely operate as a multi-inning reliever in Seattle's bullpen once he's fully up to speed.

Mariners' Jackson Kowar: Shipped to Seattle
Rotowire
Kowar and Cole Phillips (elbow) were traded from Atlanta to Seattle on Sunday in exchange for Jarred Kelenic, Marco Gonzales and Evan White, Jeff Passan of ESPN.com reports.
Kowar was traded from Kansas City to Atlanta in mid-November, and he'll be on the move once again as the Winter Meetings get underway. The 27-year-old was once a highly-regarded prospect, but he's largely struggled in the big leagues. Over 39 appearances (eight starts), he's posted a 9.12 ERA and 2.09 WHIP in 74 innings. If he earns a spot on Seattle's Opening Day roster in 2024, it's possible he has to settle for a role as a long reliever early in the year.

Braves' Jackson Kowar: Dealt to Atlanta
Rotowire
Atlanta acquired Kowar from the Royals on Friday in exchange for Kyle Wright, Anne Rogers of MLB.com reports.
Kowar owns a brutal 9.12 ERA through his first 74 major-league innings, but he was a top-100 prospect just a few years ago and can maybe find himself with a change of scenery. The reigning NL East champs could try him as a long reliever in 2024, though he also has past experience as a starter.

Royals' Jackson Kowar: Picks up second win
Rotowire
Kowar (2-0) allowed a hit and struck out two over a scoreless inning to earn the win Monday over the Guardians.
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.

Royals' Jackson Kowar: Promoted to KC
Rotowire
The Royals recalled Kowar from Triple-A Omaha on Tuesday, Anne Rogers of MLB.com reports.
Kowar and James McArthur will both come up from the minors to make up for the departures of Scott Barlow and Ryan Yarbrough at 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.

Rotowire
Kowar was optioned to Triple-A Omaha on Saturday.

Rotowire
Kansas City recalled Kowar from Triple-A Omaha on Friday.
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.

Royals' Jackson Kowar: Optioned to Triple-A
Rotowire
Kowar was optioned to Triple-A Omaha on Saturday.
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.

Royals' Jackson Kowar: Called up Wednesday
Rotowire
Kowar was called up from Triple-A Omaha on Wednesday.
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.

Royals' Jackson Kowar: Struggles in long relief
Rotowire
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.
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.

Royals' Jackson Kowar: On Opening Day roster
Rotowire
Kowar was awarded a spot on the Opening Day roster Tuesday, Anne Rogers of MLB.com reports.
The first-round pick from 2018 got his first taste of big-league action last season, but he struggled with an 11.27 ERA and 2.08 WHIP across nine appearances spanning 30.1 innings. He didn't have the best spring either, allowing four runs on eight hits and three walks through seven innings. Kowar will be able to log multi-inning assignments, though with Carlos Hernandez in the rotation, it's expected Kowar will operate out of the bullpen to begin the year.

Royals' Jackson Kowar: Charged with loss in season finale
Rotowire
Kowar (0-6) allowed five runs on five hits and a walk while striking out six in four innings to take the loss against the Twins on Sunday.
Kowar gave up four runs in the top of the first inning before recording an out, but he settled down later in his outing and retired nine consecutive batters across the next three innings. However, he was forced to finish the season with his fourth loss in his last five appearances.

Royals' Jackson Kowar: Struggles Monday
Rotowire
Kowar (0-5) got the loss after pitching 4.1 innings, giving up five runs on seven hits and walking one while striking out four versus Cleveland on Monday.
The right-hander was hit early, surrendering four runs in the first three innings including an Amed Rosario solo home run in the bottom of the third. It was the fourth straight outing for Kowar in which he gave up at least five runs. Since Sept. 7, he has thrown 15.1 innings while allowing 21 runs, good (or bad) for a 12.33 ERA. He'll look for his elusive first win in the season finale against the Twins on Sunday.
