Red Sox manager Alex Cora said that Harrison will start Saturday's game against the Rays in Tampa, Jen McCaffrey of The Athletic reports.

EDGE Analysis

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, Harrison hadn't covered five frames in an outing since Aug. 19, so the Red Sox may not be counting on the lefty working deep into his start Saturday.

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.

EDGE Analysis

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 Connelly Early.

The Red Sox recalled Harrison from Triple-A Worcester on Wednesday.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.
