• Brewers' Kyle Harrison: Making Brewers debut March 30

  Rotowire Mar 23, 2026

  Harrison (finger) is slated to make his Brewers debut March 30 against the Rays, Curt Hogg of the Milwaukee Journal Sentinel reports. Harrison had to depart his last Cactus League outing due to a blister on his left index finger, but it will not keep him from making a start during the Brewers' first turn through their rotation. Acquired from the Red Sox this offseason in the Caleb Durbin trade, Harrison permitted 12 runs (eight earned) in 9.2 innings this spring but had an encouraging 15:3 K:BB.

• Brewers' Kyle Harrison: Poised to avoid IL

  Rotowire Mar 22, 2026

  Harrison (finger) completed a bullpen session Saturday and is expected to be included on the Brewers' Opening Day roster, Adam McCalvy of MLB.com reports. Harrison exited his final Cactus League start Wednesday after developing a blister on his left index finger, but his ability to throw off a mound just a few days later puts him on track to avoid a stint on the injured list to begin the season. Milwaukee hasn't yet indicated if Harrison will pitch in either of the team's final two exhibition games Monday and Tuesday versus the Reds, but assuming the finger didn't present any issues for him during his recent bullpen session, the southpaw should be ready to make his first turn through the Milwaukee rotation once the regular season gets underway. The Brewers are still deciding where to slot Harrison in the pitching order based on the status of Brandon Woodruff (lat), who has been built up slowly during the spring but is also trending toward being included in the season-opening rotation.

• Brewers' Kyle Harrison: Hits high note again

  Rotowire Mar 9, 2026

  Harrison allowed one earned run over 3.0 innings in Sunday's spring game against the Mariners. He gave up two hits, struck out eight batters and walked two. Harrison shined while tossing three frames in an exhibition matchup against the British national team last week, and he did the same Sunday in his first official appearance of the spring. Over the two outings Harrison allowed just one earned run and posted a 10:3 K:BB, so he is making a strong case to break camp with a spot in the big-league rotation.

• Brewers' Kyle Harrison: Debuts with Brewers

  Rotowire Mar 4, 2026

  Harrison tossed 3.0 scoreless innings in Tuesday's exhibition game against the British national team. He gave up two hits, struck out two and walked one. Harrison was acquired from the Red Sox less than a month ago, and he got into his first game with the Brewers on Tuesday. The results were exceptional, thanks in part to the addition of a changeup to his arsenal, as noted by Curt Hogg of the Milwaukee Journal Sentinel. Harrison has had mixed results at the big-league level, but he is a former top prospect who has tossed 194.2 innings in the majors and owns a career K/9 of 8.8. It's unclear exactly how Milwaukee's rotation will shake out, but Harrison -- just 24 years old -- is firmly in the mix for a spot.

• Brewers' Kyle Harrison: Sent to Milwaukee in trade

  Rotowire Feb 9, 2026

  The Brewers acquired Harrison, David Hamilton and Shane Drohan from the Red Sox on Monday in exchange for Caleb Durbin, Andruw Monasterio, Anthony Seigler and a Comp B pick, Jeff Passan of ESPN.com reports. After being sent from the Giants to the Red Sox in last year's Rafael Devers trade, Harrison is on the move again. The left-hander made six starts and five relief appearances between the Giants and Red Sox last season, posting a 4.04 ERA and 38:14 K:BB across 35.2 innings. The Brewers have garnered a reputation for getting the most out of pitchers in recent years, and Harrison gives them some ability to work with. He will be among a host of competitors for one of the final spots in Milwaukee's rotation.

• Red Sox's Kyle Harrison: Hit hard in no-decision

  Rotowire Sep 26, 2025

  Harrison did not factor into the decision Friday against the Tigers, allowing three runs on seven hits and three walks over three innings. He struck out six. The Red Sox southpaw struggled out the gate, as he escaped a scoreless first inning in which he conceded two walks and a hit. The Detroit lineup finally broke through against Harrison in the fourth, when the first five batters reached, plating three runs. Given that the 24-year-old tossed 65 pitches in this appearance, he likely wraps his regular season with a 4.04 ERA, 1.37 WHIP and 38:14 K:BB across 35.2 total frames with Boston and San Francisco.

• Red Sox's Kyle Harrison: In line for another start

  Rotowire Sep 26, 2025

  Harrison is slated to start Friday's game against the Tigers in Boston. Harrison stepped in as Boston's fifth starter last weekend at Tampa Bay and aced the test, striking out five while allowing one earned run on four hits and two walks across six innings in a no-decision. The southpaw will be rewarded with another turn through the rotation Friday, and another strong showing could help his case for earning a spot on Boston's postseason roster, should the Red Sox clinch a playoff spot.

• Red Sox's Kyle Harrison: Impressive in first Red Sox start

  Rotowire Sep 21, 2025

  Harrison didn't factor into the decision Saturday against the Rays, allowing one run on four hits and two walks in six innings. He struck out five. Saturday was Harrison's first start with the Red Sox since being acquired from San Francisco as part of the Rafael Devers trade, and it couldn't have gone much better. It was the southpaw's first quality start of the season, and he also generated 11 swinging strikes. Harrison has been effective when healthy in 2025, posting a 3.58 ERA, 1.19 WHIP and 32:11 K:BB over 32.2 innings, and Boston figures to give him one more look in its rotation during the regular season next weekend against Detroit.

• Red Sox's Kyle Harrison: Recalled to big leagues

  Rotowire Sep 10, 2025

  The Red Sox recalled Harrison from Triple-A Worcester on Wednesday. Harrison is a likely candidate to serve in a bulk-relief/piggyback role Wednesday against the Athletics, following starter Payton Tolle, who is expected to be in line for a light workload. The left-handed Harrison has posted a 3.75 ERA, 1.60 WHIP and 50:27 K:BB in 50.1 innings over 12 starts with Worcester since being acquired via trade in mid-June and will be making his Red Sox debut if he gets into Wednesday's game.

• Red Sox's Kyle Harrison: Could be added to roster Wednesday

  Rotowire Sep 9, 2025

  Harrison is headed to Sacramento to join the Red Sox and could be recalled from Triple-A Worcester prior to Wednesday's game against the Athletics, Tommy Cassell of the Worcester Telegram & Gazette reports. The Red Sox have not yet announced a starter for Wednesday's game, though manager Alex Cora said that lefty Payton Tolle is expected to be used in some capacity. Harrison could also be in the mix, perhaps in a tandem start with Tolle. The left-handed Harrison pitched one inning with Triple-A Worcester on Sunday after overcoming an ankle injury, so he would be pitching on two days' rest Wednesday. Harrison holds a 3.75 ERA and 50:27 K:BB over 50.1 innings with Worcester since the Red Sox acquired him from the Giants on June 15.

• Red Sox's Kyle Harrison: Returns to action for Triple-A club

  Rotowire Sep 8, 2025

  Harrison (ankle) made a one-inning start for Triple-A Worcester in the first game of a doubleheader Sunday, striking out two batters while allowing one earned run on two hits and one walk. Harrison appeared to be a candidate to make a start or bulk-relief appearance with the Red Sox last week, but he sustained a minor ankle injury that may have played a part in him being bypassed for a promotion. The southpaw made enough progress in his recovery from the injury to pitch Sunday for Worcester, though he took on a much more limited workload than he typically handles during his starts.

• Red Sox's Kyle Harrison: Managing ankle injury

  Rotowire Sep 3, 2025

  Triple-A Worcester manager Chad Tracy said Wednesday that Harrison is tending to an ankle injury, and the southpaw is without a clear timeline to resume pitching, Katie Morrison-O'Day of MassLive.com reports. The southpaw had recently joined the Red Sox in Boston and appeared to be in consideration for a start Wednesday against the Guardians, but the big club will ultimately have lefty Brennan Bernardino serve as an opener in front of bulk reliever Dustin May in that contest. Harrison's ankle injury may have played a part in him being bypassed for the start with Boston, and it's yet to be determined whether the issue will result in him landing on Worcester's injured list.

• Red Sox's Kyle Harrison: Won't be promoted after all

  Rotowire Sep 3, 2025

  The Red Sox are not planning to recall Harrison from Triple-A Worcester prior to Wednesday's game versus the Guardians, Alex Speier of the Boston Globe reports. Previous reports indicated that Harrison was headed to Boston and could start Wednesday's contest. However, the club has since announced that Brennan Bernardino will open the contest, with Dustin May slated for bulk relief. Harrison could still get an opportunity with the Red Sox at some point this month, but he'll remain with Worcester for now. The lefty has posted a 3.65 ERA and 48:26 K:BB over 49.1 innings covering 11 starts with Worcester after being dealt to Boston in the Rafael Devers trade.

• Red Sox's Kyle Harrison: Set to join big club

  Rotowire Sep 2, 2025

  The Red Sox are expected to recall Harrison from Triple-A Worcester prior to Wednesday's game against the Guardians, Tommy Cassell of the Worcester Telegram & Gazette reports. The Red Sox have yet to announce a starter for Wednesday, but Harrison is likely to slot into that spot. Acquired from the Giants in mid-June, Harrison has a 3.65 ERA and 48:26 K:BB over 49.1 innings covering 11 starts since joining Worcester, which includes a 2.00 ERA and 19:9 K:BB across his last 18 frames. Whether the lefty draws additional starts for Boston could depend on if the club wants to keep a six-man rotation for a stretch.

• Red Sox's Kyle Harrison: Revamping repertoire in minors

  Rotowire Jun 26, 2025

  Harrison is working on revamping his repertoire at Triple-A Worcester before joining their rotation, Tommy Cassell of the Worcester Telegram & Gazette reports. Acquired from the Giants in the Rafael Devers trade, Harrison worked on some new pitches -- including a cutter and sinker -- during a live batting practice session this week. The lefty threw a four-seamer, slurve and changeup during his time in San Francisco, with Red Sox director of pitching Justin Williard calling the four-seamer a "unique fastball that's going to be his bread and butter." The Red Sox want Harrison to find some consistent secondary offerings to pair with the four-seamer, and senior director of player development Brian Abraham said "the returns have been really good so far" with the southpaw. Harrison figures to make at least a couple starts with Worcester as he works on his new offerings, but the plan seems to be to have him as part of Boston's rotation sooner rather than later.

• Red Sox's Kyle Harrison: Opening at Triple-A after trade

  Rotowire Jun 15, 2025

  The Red Sox optioned Harrison to Triple-A Worcester after acquiring him from the Giants on Sunday. Along with Harrison, the Red Sox brought in right-handers Jordan Hicks (toe) and Jose Bello and outfielder James Tibbs in a deal that sent designated hitter Rafael Devers to San Francisco. Though Harrison will likely be an option to make starts for the Red Sox later this season, the big club didn't have a spot available for him in the rotation, so he'll begin his tenure in the organization at Triple-A. The left-hander turned in a 4.48 ERA and 1.30 WHIP with 178 strikeouts over 182.2 innings in 39 appearances (35 starts) during parts of three seasons in the majors with the Giants.

• Red Sox's Kyle Harrison: Traded to Boston

  Rotowire Jun 15, 2025

  The Red Sox acquired Harrison, right-hander Jordan Hicks (toe), right-hander Jose Bello and outfielder James Tibbs from the Giants on Sunday in exchange for Rafael Devers, Robert Murray of FanSided.com reports. Harrison had been slated to start for the Giants in Sunday's series finale against the Dodgers, but he was scratched just minutes before the game after the trade was completed. The left-hander had compiled a 4.56 ERA and 1.27 WHIP with 25 strikeouts over 23.2 innings in eight appearances (four starts) for San Francisco. The Red Sox are likely to have Harrison continue his development as a starter, but the team may not have an immediate opening for the 23-year-old in the big-league rotation. Harrison has three minor-league options remaining and could be sent to Triple-A Worcester to continue making regular starts.

• Giants' Kyle Harrison: Logs five innings in no-decision

  Rotowire Jun 11, 2025

  Harrison did not factor into the decision Tuesday, allowing three runs on four hits and two walks over five innings against the Rockies. He struck out six. The left-hander was burned by the long ball Tuesday, giving up home runs to Ryan McMahon and Kyle Farmer. Harrison has made four starts since joining the rotation May 24, with mixed results. The 23-year-old owns a 4.91 ERA and 1.36 WHIP over 18.1 innings as a starter, compared to a 3.38 ERA and 0.94 WHIP in 5.1 innings out of the bullpen.

• Giants' Kyle Harrison: Cleared for next start

  Rotowire Jun 9, 2025

  Harrison (elbow) is listed as the Giants' probable starter for Tuesday's game against the Rockies in Colorado. Harrison's previous start last Wednesday against the Padres was cut short after he was struck on the left elbow by a comebacker midway through the fifth inning, but he escaped the incident with nothing more than a bruise. The southpaw was able to complete his between-starts bullpen session over the weekend and looks set to pitch Tuesday with no restrictions. However, Harrison -- who owns a 4.73 ERA, 1.43 WHIP and 12:4 K:BB in 13.1 innings over his previous three starts -- won't make for a comfortable streaming option in a road start at hitter-friendly Coors Field.

• Giants' Kyle Harrison: Nursing bruised elbow

  Rotowire Jun 5, 2025

  Harrison was diagnosed with a left elbow contusion after getting hit by a comebacker during Wednesday's game against San Diego, Alex Pavlovic of NBC Sports Bay Area reports. Harrison took a grounder off his elbow during the fifth inning of Wednesday's contest and was immediately pulled from the game. However, it appears he escaped from the incident with only a bruise. A team day off Monday will give Harrison an extra day to rest before his next scheduled start, but the Giants will wait a few days to see how he recovers before they pencil him in for another outing. The southpaw allowed five runs on nine hits and one walk while striking out three batters in 4.2 frames Wednesday and finished with a no-decision.
