Hit hard in no-decision Harrison allowed three runs on seven hits and three walks over three innings while not factoring into the decision Friday against the Tigers. He struck out six.
Impact 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, with 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.

In line for another start Harrison is slated to start Friday's game against the Tigers in Boston.
Impact 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.

Impressive in first Red Sox start 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.
Impact 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.

SEPTEMBER 18 • Associated Press
In line for start Saturday Red Sox manager Alex Cora said that Harrison will start Saturday's game against the Rays in Tampa, Jen McCaffrey of The Athletic reports.
Impact Harrison will move into the rotation as a replacement for rookie lefty Payton Tolle, whom Cora said would be used in the bullpen for the remainder of the season. After getting called up from Triple-A Worcester last week, Harrison made his Red Sox debut out of the bullpen Sept. 10 in Sacramento, striking out two over three scoreless innings. Though he had been serving in a starting role for Worcester, he hadn't covered five innings in an outing since Aug. 19, so the Red Sox may not be counting on the lefty working deep into his start Saturday.

Makes Boston debut Harrison allowed three hits, hit a batter and struck out two over three scoreless relief innings in Wednesday's 5-4 loss to the Athletics.
Impact Harrison pitched the final three innings in a piggyback outing that was started by Payton Tolle (two innings). Harrison isn't fully built up after a series of stops and starts over the last couple of weeks that included an ankle injury. He could be a factor later in September, as he unlikely has the same innings limits of rookies Tolle and Connolly Early.

Recalled to big leagues The Red Sox recalled Harrison from Triple-A Worcester on Wednesday.
Impact Harrison is a likely candidate to serve in a bulk relief/piggyback role Wednesday against the Athletics, following starter Payton Tolle. 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 June and will be making his Red Sox debut when he gets into a game.

Recalled to big leagues The Red Sox recalled Harrison from Triple-A Worcester on Wednesday.
Impact 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.

Could piggyback Tolle on Wednesday The Red Sox plan to recall Harrison from Triple-A Worcester ahead of Wednesday's game against the Athletics in Sacramento, Chris Cotillo of MassLive.com reports.
Impact Though manager Alex Cora has confirmed that Payton Tolle will start Wednesday's contest, the rookie southpaw will be in line for an abbreviated appearance since he'll be pitching on less than five days' rest for the first time as a professional. According to Cotillo, Cora wouldn't reveal his plans for once Tolle exits the contest, but Harrison would make sense in a piggyback role. Since being acquired from the Giants in mid-June, Harrison has yet to make his Boston debut and has been working out of the rotation at Worcester, turning in a 3.75 ERA, 1.60 WHIP and 50:27 K:BB in 50.1 innings over 12 starts. He made a one-inning appearance Sunday and should be capable of covering multiple frames Wednesday in relief of Tolle.
