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.
EDGE Analysis
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.

The Red Sox are expected to recall Harrison from Triple-A Worcester, Tommy Cassell of the Worcester Telegram and Gazette reports.
EDGE Analysis
The Red Sox have yet to announce a starter for Wednesday's game against the Guardians at Fenway Park, and Harrison is likely to slot into that spot. Acquired from the Giants in the Rafael Devers trade, 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.

Harrison was scratched ahead of his scheduled start with Triple-A Worcester and could be called up to start or pitch in bulk relief Wednesday against the Guardians in Boston, Chris Hatfield of SoxProspects.com reports.
EDGE Analysis
Harrison had been a candidate to join the big-league rotation this past week when the Red Sox moved Walker Buehler to the bullpen and later released him, but the southpaw was bypassed for a promotion in favor of fellow Triple-A starter Payton Tolle. Though Tolle impressed in his MLB debut while striking out eight batters and allowing two earned runs over 5.1 innings in Friday's 4-2 loss to the Pirates, the Red Sox appear committed to keeping the 22-year-old on at least a five-day rest schedule between outings. As a result, Tolle doesn't appear to be in line to start Wednesday's series finale versus the Guardians, opening the door for Harrison or another pitcher to temporarily step into the rotation. The Red Sox could also opt to treat Wednesday's game as a bullpen day in lieu of calling up Harrison, who has submitted a 3.65 ERA and 1.57 WHIP in 49.1 innings with Worcester this season.

Harrison could be recalled from Triple-A Worcester to start Monday's series opener against the Orioles, Chris Cotillo of MassLive.com reports.
EDGE Analysis
After the Red Sox moved Walker Buehler to the bullpen Friday, the club needs a starter for Monday's contest. The leading contenders to fill the void in the rotation would seem to be Harrison and Richard Fitts, the latter of whom was recalled from Triple-A on Thursday and was made available out of the bullpen. Fitts has gone unused in the first three games of the Red Sox's series with the Yankees, and if Boston stays away from him again Sunday, the right-hander would likely be the top candidate to take the hill Monday. Acquired from the Giants in the June 15 deal that sent Rafael Devers to San Francisco, Harrison has yet to make his Red Sox debut. The 24-year-old southpaw has thus far made 10 starts for Worcester, turning in a 3.69 ERA, 1.60 WHIP and 46:25 K:BB in 46.1 innings.

Harrison allowed four runs on eight hits and one walk while striking out four over four innings for Triple-A Worcester on Thursday.
EDGE Analysis
Harrison was nicked for a pair of runs in each of the first and third innings, including a home run, in his debut for the organization. He was part of the package Boston acquired from San Francisco in the Rafael Devers trade. The right-hander threw mostly fastballs, per

Harrison is working on revamping his repertoire at Triple-A Worcester before joining their rotation next week, Tommy Cassell of the Worcester Telegram & Gazette reports.
EDGE Analysis
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.

Harrison was optioned to Triple-A Worcester after being traded to the Red Sox on Sunday.
EDGE Analysis
Harrison will report to Triple-A Worcester to begin his tenure with his new team. The left-hander owns a career 4.48 ERA and 1.30 WHIP with 178 strikeouts over 182.2 innings in 39 appearances, including 35 starts, with the Giants. He figures to project as a long-term asset as a starting pitcher for the Red Sox and his time in Triple-A will likely be short-lived.

Harrison was traded to the Red Sox as a part of a deal that returned Rafael Devers to the Giants on Sunday, Robert Murray of FanSided.com reports.
EDGE Analysis
Harrison will no longer make his start Sunday night versus the Dodgers, and he will no longer be a member of the Giants' organization. The left-hander has compiled a 4.56 ERA and 1.27 WHIP with 25 strikeouts over 23.2 innings while posting a 1-1 record in eight appearances, including four starts, with San Francisco in 2025. Harrison could slot into Boston's starting rotation moving forward or operate as a bullpen arm. Right-handed reliever Jordan Hicks (toe) was also among the assets heading to Boston on Sunday.

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.
EDGE Analysis
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.

Harrison (elbow) is listed as the Giants' probable starter for Tuesday's game against the Rockies in Colorado.
EDGE Analysis
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.
