Bleis (quadricep) is slashing .161/.257/.387 with two home runs, two stolen bases and 10 RBI in eight games since making his season debut for High-A Greenville on April 9.
Though Greenville never officially placed Bleis on the injured list, the 21-year-old outfielder didn't play in any of the team's first four games while he tended to a minor quad injury. Since being cleared to make his 2025 debut, Bleis has performed at a below-league-average level (81 wRC+) while striking out at a 34.3 percent clip.
Red Sox's Miguel Bleis: Sidelined with quad injury
Rotowire
Bleis is sidelined to start the season at High-A Greenville with a minor quadriceps injury, Jim Callis of MLB Pipeline reports.
Bleis will open the year on the 7-day injured list, but it sounds like he'll be active in weeks, not months. Injuries have impacted Bleis' development thus far, as 2024 was his first year playing over 50 games in a season, and he has yet to play 100 games in a season. The toolsy outfielder hit .190 (.219 BABIP) with seven home runs and 22 steals in 52 games at High-A last year.

Red Sox's Miguel Bleis: Elevated to High-A
Rotowire
The Red Sox promoted Bleis from Single-A Salem to High-A Greenville on Monday, Alex Speier of The Boston Globe reports.
Bleis' 2023 season came to an early end after he underwent surgery on his left shoulder last June, but he was cleared ahead of the 2024 season and has bounced back effectively from the procedure. Over his 195 plate appearances with Salem, Bleis slashed .257/.349/.398 with four home runs and 16 stolen bases.

Red Sox's Miguel Bleis: Shows improving plate discipline
Rotowire
Bleis is batting .200/.313/.309 through 14 games for Low-A Salem.
The middling numbers Bleis posted in 2023 continued to start the current season, but there's encouraging signs beneath the slash line. The outfield prospect, a notorious free-swinger, has posted a 12.5 percent walk rate (up from 7.4 percent in 2023) while cutting down on strikeouts (17.2 percent, down from 26.8 percent). Better swing decisions could eventually lead to more promising outcomes.
Bleis, whom Single-A Salem placed on the 7-day injured list June 1, is soon expected to undergo left shoulder surgery and will miss the rest of the season, Chris Henrique of Beyond the Monster reports.
The 19-year-old outfielder will head into the offseason with a .230/.282/.325 slash line, one home run and 11 steals in 31 games in his first exposure to full-season pitching at Single-A Salem. Given the middling production and long layoff, his dynasty value will be trending down over the next year, but Bleis still has loud tools and will return to Salem for his age-20 season.

Red Sox's Miguel Bleis: Opening at Single-A
Rotowire
Bleis will report to Single-A Salem for the start of the minor-league season, Rob Bradford of WEEI.com reports.
Bleis will make his debut in full-season ball after he played exclusively in the rookie-level Florida Complex League as an 18-year-old in 2022. The assignment to Salem doesn't come as a surprise after the outfielder proved worthy of a tougher test by slashing .294/.347/.536 with five home runs and 18 stolen bases in 167 plate appearances in the FCL.
Bleis went 1-for-2 with two RBI in Monday's spring game against the Blue Jays.
Boston's highly touted outfield prospect made his second Grapefruit League appearance and first start, and he showed off both his defensive and offensive skills. In the bottom of the first he threw a strike to home plate to nail Brandon Belt by several steps. A half-inning later, Bleis fought off a two-strike fastball in on his hands from Alek Manoah, going the other way to drive in a pair of runs. He also had a fielding miscue, which is a reminder the 19-year-old is still relying on his raw tools. He played 40 games last season in the rookie-level Florida Complex League, batting .301/.543/.896 with 23 extra-base hits and 18 steals. Bleis should get a taste of full-season ball in 2023.

Red Sox's Miguel Bleis: Intriguing results in rookie ball
Rotowire
Blais has a .301/.353/.542 slash line with five homers and 18 steals across 40 games in the rookie-level Florida Complex League this season.
A 2021 international signee from the Dominican Republic, Bleis showed off his speed and extra-base ability in rookie ball this year, but he also struck out in 26.9 percent of his plate appearances with just a 6.0 percent walk rate. Usually, talented youngsters like him show far better plate discipline in the low minors. He also had a .394 BABIP; normalize that, and his stats suddenly don't look so spectacular anymore. There's real upside here, but Bleis comes with plenty of bust risk as well.
