Royals' Jackson Kowar: Charged with loss in season finale
by RotoWire Staff | 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. The right-hander made nine appearances (eight starts) during his first major-league season and recorded an 11.27 ERA and 2.08 WHIP in 30.1 innings.

Royals' Jackson Kowar: Struggles Monday
by RotoWire Staff | 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.

Royals' Jackson Kowar: Hit hard again Sunday
by RotoWire Staff | RotoWire

Kowar (0-4) allowed five runs on seven hits and three walks while striking out three over four innings as he took the loss against the Mariners on Sunday.

Kowar was knocked around again in what was his third straight start allowing five runs or more. He gave up two in the first on a double from Jarred Kelenic, another in the second and two more in the third on a pair of solo home runs. His success in the minors has certainly not translated over to the big leagues just yet. The 24-year-old righty now owns an 11.45 ERA, 2.23 WHIP and 19:18 K:BB over 22 innings. He should be avoided in lineups at all costs for the remainder of the season.

Royals' Jackson Kowar: Lasts one inning Tuesday
by RotoWire Staff | RotoWire

Kowar didn't factor into the decision Tuesday against Oakland after allowing five runs on three hits and four walks across one inning, fanning one. He also tossed a wild pitch.

It's not a secret that Kowar has struggled mightily in his first big-league campaign, but this one could go down easily as his worst start to date. The fact that he hasn't been able to complete two full innings in three of his six appearances is concerning, but so is the fact that he has allowed at least four runs in four of those six starts. With those numbers, the fact that he owns an 11.50 ERA with a 2.17 WHIP and a 7.5 BB/9 through 18 big-league innings shouldn't be surprising.

Royals' Jackson Kowar: Thumped by Orioles
by RotoWire Staff | RotoWire

Kowar (0-3) took the loss Tuesday, coughing up six runs on five hits and three walks over six innings as the Royals fell 7-3 to the Orioles. He struck out seven.

The strikeouts were a silver lining on an otherwise stormy performance, as Kowar got taken deep by DJ Stewart in the first inning and Austin Hays in the third to account for most of the damage off him. The 24-year-old has lasted six innings in each of his last two starts, but his 9.53 ERA, 1.94 WHIP and 15:12 K:BB through his first 17 big-league innings makes Kowar impossible to trust in fantasy lineups.

Royals' Jackson Kowar: Picks up another start
by RotoWire Staff | RotoWire

Kowar will draw a second straight turn through the Kansas City rotation in Tuesday's game at Baltimore, Anne Rogers of reports.

After joining Kansas City when the roster expanded from 26 to 28 men, Kowar slotted back into the team's rotation. He delivered a quality start Sept. 1 in a no-decision versus Cleveland, striking out six over six innings while giving up two runs on five hits and three walks. The Royals will reward Kowar with another start as a result, and he should hold down a spot in the team's six-man rotation until one of Brad Keller (lat) or Jakob Junis (shoulder) returns from the injured list.

Royals' Jackson Kowar: Posts best start of young career
by RotoWire Staff | RotoWire

Kowar did not factor in the decision against Cleveland on Wednesday, pitching six innings and allowing two earned runs on four hits and three walks while striking out six.

The rookie right-hander posted an ugly 18.00 ERA across three outings earlier this season, but he looked like a different pitcher after being called up to start Wednesday. Kowar allowed only two hits through four scoreless innings before a two-out error led to a pair of fifth-inning runs, but he bounced back with a scoreless sixth frame, retiring his final two batters of the night via strikeout. The strong performance could earn Kowar another turn in the rotation, a scenario made more likely with Jakob Junis (shoulder) landing on the injured list Wednesday.

Royals' Jackson Kowar: Gets call-up ahead of start
by RotoWire Staff | RotoWire

The Royals recalled Kowar from Triple-A Omaha ahead of his scheduled start Wednesday against Cleveland.

The addition of Kowar will give the other Kansas City starters some extra rest between outings, but the 24-year-old right-hander won't necessarily become a fixture in the rotation in September. He faltered badly in a three-outing stint with the big club back in June (18.00 ERA, 3.20 WHIP in five innings), and he wasn't overly impressive upon returning to Triple-A, submitting a 5.14 ERA and 1.47 WHIP in 49 innings. Kowar at least appeared to turn a corner in his most recent two Triple-A starts, working 11 innings between those outings while giving up two earned runs and posting a 16:2 K:BB.

Royals' Jackson Kowar: Returning to start Wednesday
by RotoWire Staff | RotoWire

Kowar will be recalled from Triple-A Omaha to start Wednesday against Cleveland, Josh Vernier of 610 Sports Kansas City reports.

Kowar made his big-league debut in June and returned to the minors after surrendering 10 earned runs over five innings (three appearances), and he'll rejoin the Royals on Wednesday for another look. The 24-year-old hasn't been particularly effective at Triple-A since the demotion with a 5.14 ERA, 1.47 WHIP and 74:24 K:BB, though he's given up two runs with a 16:2 K:BB in his past two outings (11 innings).

Royals' Jackson Kowar: Banished to minors
by RotoWire Staff | RotoWire

The Royals optioned Kowar to Triple-A Omaha on Wednesday.

The writing was on the wall for Kowar's demotion after the Royals shifted him to the bullpen after a disastrous first two starts following his June 7 promotion from Triple-A Omaha. After giving up eight earned runs while recording only six outs between the two starts, Kowar fared only marginally better in long relief Saturday against the Red Sox, surrendering two runs on three hits over two innings. He'll slot back into the rotation at Omaha and will look to recapture some success before the Royals entertain the idea of calling him up again.

Royals' Jackson Kowar: Logs three innings in relief
by RotoWire Staff | RotoWire

Kowar allowed two runs on three hits and struck out one in three innings in Saturday's 7-1 loss to Boston.

Kowar was called upon for a bulk relief assignment, and his first two innings went well. The right-hander struggled in the ninth as Bobby Dalbec hit a two-run home run. Bizarrely, this relief outing was Kowar's longest of three appearances this year, even though the first two were starts. He's still allowed 10 runs across five innings to begin his major-league career. It's unclear if the 24-year-old will reenter the rotation next week -- if he does, it'll likely be versus the Yankees if he stays on regular rest.

Royals' Jackson Kowar: Available out of bullpen Friday
by RotoWire Staff | RotoWire

Kowar will be available to pitch in relief Friday against the Red Sox, Lynn Worthy of The Kansas City Star reports.

Kowar originally lined up to start the series opener, but the Royals are opting to utilize Kyle Zimmer as an opener in place of the struggling rookie. The Royals have not directly said that Kowar will serve as the bulk man out of the bullpen Friday, but he figures to be an option to provide length following Zimmer's presumed early exit.

Royals' Jackson Kowar: Not starting Friday
by RotoWire Staff | RotoWire

Kowar will not start Friday's game against the Red Sox.

Kowar was in line to take the ball for Friday's series opener, but it will be Kyle Zimmer toeing the rubber instead. Kowar struggled mightily in his first two starts, allowing a total of eight earned runs on eight hits and five walks while failing to work past the second inning in either outing. The plan going forward isn't entirely clear for the right-hander, but assuming he isn't sent down prior the game, he could be an option to provide length out of the bullpen Friday.

Royals' Jackson Kowar: Poor performance once again
by RotoWire Staff | RotoWire

Kowar (0-2) was tagged with the loss Saturday against the Athletics after allowing four runs on five hits and three walks across 1.1 innings. He struck out one.

It was another rough outing for Kowar and even though he was able to get out of the first inning this time, he didn't make a substantial improvement compared to his debut and once again delivered a below-average outing. It remains to be seen how patient the Royals will be with their star prospect. Right now, it's not entirely clear that he'll get another shot in the rotation any time soon.

Royals' Jackson Kowar: Gets another shot after rough debut
by RotoWire Staff | RotoWire

Kowar is scheduled to start Saturday's game in Oakland, Lynn Worthy of The Kansas City Star reports.

The 24-year-old right-hander couldn't make it out of the first inning in his highly anticipated MLB debut Monday, recording just two outs while surrendering four runs on three hits and two walks en route to taking a loss. Ervin Santana performed better in long relief (three earned runs allowed in four innings), but the Royals won't look to make a change to their rotation after Kowar's shaky debut. Kowar will have nowhere to go but up Saturday, though he may need to make notable improvements in his control and command to ensure he receives a third turn through the rotation.

Royals' Jackson Kowar: Woeful in pro debut
by RotoWire Staff | RotoWire

Kowar (0-1) was tagged with the loss Monday against the Angels after allowing four runs on three hits and two walks across two-thirds of an inning.

This wasn't the outing Kowar was expecting, as he couldn't even get out of the first inning and was lifted after giving up four runs and not striking out anyone. He could be lined up for a two-start week since he'd be tentatively up to pitch during the weekend series in Oakland, but that remains to be seen considering how much he struggled in his pro debut.

Royals' Jackson Kowar: Contract selected for MLB debut
by RotoWire Staff | RotoWire

Kowar's contract was selected as expected ahead of his big-league debut Monday against the Angels.

Heading into this season, Kowar was a real prospect but not an elite one, as he'd produced a 3.50 ERA and a modest 22.8 percent strikeout rate in 35 minor-league starts. He burst out of the gate this season for Triple-A Omaha, however, striking out 33.9 percent of opposing batters en route to a 0.85 ERA through six starts, thanks in part to an improvement in his previously fringy curveball. If he pitches well enough in his debut start to earn a permanent place in the Royals' rotation, he'd line up for a two-start week this week, as he'd likely pitch during the weekend series in Oakland. Jakob Junis was optioned to clear a spot for him on the active roster.

Royals' Jackson Kowar: Slated to debut Monday
by RotoWire Staff | RotoWire

Kowar will be called up to start Monday's game against the Angels, Josh Vernier of 610 Sports reports.

Kowar was dominant in the minors to begin the season, and he was named the Triple-A East pitcher of the month in May. Across six starts for Triple-A Omaha, the right-hander posted a 0.85 ERA, 0.90 WHIP and 41:10 K:BB in 31.2 innings. Kowar boasts a mid-90s fastball and an elite changeup and will fill in while Danny Duffy (forearm) is sidelined, though the 24-year-old could also make a case for a long-term rotation spot.

Royals' Jackson Kowar: Takes home Triple-A honor
by RotoWire Staff | RotoWire

Kowar was named the Triple-A East pitcher of the month Wednesday after he went 5-0 with a 1.01 ERA, 0.99 WHIP and 36:9 K:BB across 26.2 innings in his first five starts of the season.

The Royals already gave Daniel Lynch a look at the big-league level earlier this season, and Kowar is putting himself in position to be the next high-profile pitching prospect to earn a call-up. Kansas City currently has Ervin Santana filling in as its No. 5 starter while Danny Duffy (forearm) is on the shelf, but the 38-year-old isn't viewed as anything more than a temporarily option for a 27-26 Royals squad that was beginning to fade from the wild-card race prior to its ongoing three-game winning streak. Expect Kansas City to eventually make developing its younger options a greater priority as the season unfolds, making the 24-year-old Kowar an attractive pitcher to stash in deeper leagues.

Royals' Jackson Kowar: Bound for MiLB camp
by RotoWire Staff | RotoWire

The Royals reassigned Kowar to their minor-league camp Monday.

Kansas City sent several of its top prospects back to minor-league camp Monday, as Kowar was reassigned along with infielder Bobby Witt, outfielder Kyle Isbel and pitcher Daniel Lynch. Kowar will likely open the 2021 campaign at Triple-A Omaha after posting a 3.51 ERA, 1.27 WHIP and 78:21 K:BB across 74.1 innings at Double-A Northwest Arkansas in 2019.
