Red Sox prospect Max Carlson named Eastern League Pitcher of the Week

Red Sox pitching prospect Max Carlson has been named the Eastern League Pitcher of the Week for the week of July 20-26, Minor League Baseball announced on Monday.

Carlson made two scoreless relief appearances in Double-A Portland’s road series against Binghamton last week. The 24-year-old right-hander worked 5 2/3 hitless innings altogether, issuing just one walk and striking out seven. He recorded his first save of the season with three perfect frames out of the bullpen on Friday.

Dating back to June 7, Carlson has posted a 2.52 ERA with 28 strikeouts to only four walks over his last 25 innings pitched. Overall, the righty owns a 5.03 ERA with 65 strikeouts to 13 walks across 26 appearances (one start) and 59 innings for Portland this season. Opposing Eastern League hitters are slashing .268/.311/.425 against him.

Among 46 Eastern League pitchers who have thrown at least 55 innings this year, Carlson ranks fourth in swinging-strike rate (15.9%) and walks per nine (1.98), fifth in walk rate (5.3%), seventh in FIP (3.86), ninth in WHIP (1.25) and xFIP (3.79), 16th in strikeout rate (26.5%), and 17th in strikeouts per nine (9.92), according to FanGraphs.

Carlson is in his third full professional season and first at the Double-A level. The Minnesota native was originally selected by the Red Sox in the 12th round (358th overall) of the 2023 draft out of the University of North Carolina. He reached High-A Greenville early on in 2024, but was limited to just 11 outings (35 1/3 innings) there last year due to a right shoulder impingement that required a season-ending trip to the 60-day injured list.

Now healthy, Carlson has proven to be a reliable option out of Portland’s bullpen this season. The 6-foot-1, 190-pound hurler does not overwhelm hitters with pure velocity, topping out at 94 mph with a low-90s fastball while mixing in a changeup, slider, and sweeper. Though he is not ranked among Boston’s top pitching prospects by outlets such as SoxProspects.com, he commands the strike zone effectively, allowing his stuff to play up.

Carlson, who turns 25 in September, is the fifth different Portland pitcher to earn Eastern League Pitcher of the Week honors this season, joining John Holobetz, Patrick Halligan, Anthony Eyanson, and Blake Wehunt. Given that he can become Rule 5-eligible for the first time this winter, it would not be surprising to see Carlson leverage his recent performance into a promotion to Triple-A Worcester before long.

Red Sox pitching prospect Max Carlson has several ‘traits teams look for in a major-league reliever’

In the 12th round of last year’s draft, the Red Sox selected North Carolina right-hander Max Carlson.

Taken with the 358th overall pick, Carlson signed with Boston for $150,000 and marked his professional debut by making one scoreless relief appearance in the Florida Complex League shortly thereafter. He then broke camp with Low-A Salem for the start of his first full pro season earlier this spring.

Carlson appeared in three of Salem’s first 11 games, allowing seven runs (five earned) over 8 1/3 innings, before being elevated to High-A Greenville on April 20. However, that assignment would prove to be short-lived, as Carlson was sent back to Salem three days later after pitching in just one game for the Drive.

For the better part of the next four months, Carlson established himself as a key member of Salem’s bullpen. From April 25 through the MLB All-Star break in July, the righty posted a 1.34 ERA with 45 strikeouts to 11 walks over 17 appearances (33 2/3 innings). Opposing hitters batted just .198 against him in that stretch.

Though he struggled some upon returning from the break, most notably surrendering a season-worst six earned runs to Carolina on July 27, Carlson pitched well enough to earn another promotion to the High-A level on August 20. He then closed out the 2024 campaign by producing a 1.80 ERA in four appearances (10 innings) for Greenville. That includes tossing a season-high five frames of one-run ball in his final outing of the year against Winston-Salem on September 6.

Altogether, Carlson forged a 2.73 ERA and 2.41 FIP with 86 strikeouts to 23 walks in 33 total relief appearances (69 1/3 innings) between Salem and Greenville in 2024. Among the 39 Red Sox minor-leaguers who threw at least 65 innings this year, Carlson ranked first in FIP, second in ERA and swinging-strike rate (17.2 percent), third in xFIP (3.13), ninth in strikeouts per nine innings (11.16) and walks per nine innings (2.99), 10th in walk rate (7.7 percent), 11th in strikeout rate (28.9 percent), and 17th in WHIP (1.27), per FanGraphs.

Carlson, who turned 23 in September, was recognized as a 2024 SoxProspects.com All-Star last month. The Minnesota native is currently regarded by the outlet as the No. 42 prospect in Boston’s farm system, which ranks 23rd among pitchers in the organization.

Though he is not ranked among Boston’s top farmhands by publications such as Baseball America at the moment, Carlson was identified by BA’s Geoff Pontes as a pitching prospect with “elite” traits on his four-seam fastball earlier this summer.

“Carlson only sits 91-92 mph but has over seven feet of extension, above-average vertical break, and arm-side run, allowing his fastball to play above its below-average velocity,” Pontes wrote in August. “It’s a classic three-quarters arm slot, but the release and plane on the pitch play up due to his combination of extension and spin efficiency.”

In addition to throwing a fastball that can touch 95 mph, Carlson operates with a 79-81 mph changeup that has “late fade” and a 79-82 mph sweeping slider “that lacks depth at times,” per his SoxProspects.com scouting report, which notes that the 6-foot-1, 190-pound hurler has several traits “teams look for in a major-league reliever that could make him a more interesting bullpen prospect.”

To that end, Carlson — assuming he remains in the organization through the winter — is projected by SoxProspects.com to return to Greenville as a member of the Drive’s bullpen to start the 2025 minor-league season.

Red Sox promote pitching prospect Max Carlson to High-A Greenville

The Red Sox have promoted pitching prospect Max Carlson from Low-A Salem to High-A Greenville, according to the club’s MiLB.com transactions log.

Carlson, 22, has made three appearances out of the Salem bullpen to begin his first full professional season. The right-hander has allowed seven runs (five earned) on nine hits and four walks to go along with 14 strikeouts over 8 1/3 innings of relief. That translates to a 5.40 ERA, though he owns a more favorable 3.60 FIP and 2.98 xFIP.

A native of Minnesota, Carlson was selected by Boston in the 12th round of last year’s draft out of the University of North Carolina. The former Tar Heel was ranked by Baseball America as the No. 385 prospect in his class. He signed with the Red Sox for $150,000 and made his pro debut in the Florida Complex League, tossing a scoreless sixth inning in his lone outing of the year.

Listed at 6-foot-1 and 190 pounds, Carlson throws from a three-quarters arm slot and utilizes a full wind-up in his delivery. The righty operates with a three-pitch mix that consists of a 90-93 mph that tops out at 95 mph, a whiff-inducing changeup that sits in the low-80s, and an infrequently-used 81-84 mph slider, per his SoxProspects.com scouting report.

Carlson, who does not turn 23 until September, is the second member of Boston’s 2023 draft class to earn a promotion in as many weeks. Lefty Zach Fogell, the club’s 18th-round pick out of Connecticut, also made the jump from Salem to Greenville last Friday.

In addition to promoting Carlson, the Red Sox added outfielder Kelvin Diaz to Salem’s roster from extended spring training. Diaz, 21, stole 21 bases in 48 Florida Complex League games last season. He originally signed with Boston for $300,000 as an international free agent coming out of the Dominican Republic in July 2019.

Red Sox select North Carolina righty Max Carlson with 12th-round pick in 2023 MLB Draft

The Red Sox have selected North Carolina right-hander Max Carlson with their 12th-round pick in the 2023 MLB Draft at No. 358 overall.

Carlson was regarded by Baseball America as the No. 385 prospect in this year’s draft class. The 21-year-old junior posted a 5.45 ERA and 1.39 WHIP with 76 strikeouts to 32 walks in 17 appearances (14 starts) spanning 76 innings of work for the Tar Heels this past season. Opposing hitters batted .256 against him.

Listed at 6-foot-1 and 210 pounds, Carlson “pitches in the 90-93 mph range and touches 95, and uses a low-80s changeup as his primary secondary and swing-and-miss pitch,” per his Baseball America scouting report. “He generated a 40% miss rate with the changeup this spring, which was far and away his most effective bat-missing offering. He’ll also mix in a low-80s slider, but he used the pitch at just a 7% rate.”

The younger brother of Mariners minor-league righty Sam Carlson, Max was a well-regarded pitching prospect coming out of high school but was not drafted in 2020. The Minnesota native instead took his talents to Chapel Hill and had the best year of his collegiate career as a sophomore, pitching to a 3.71 ERA over 18 starts (77 2/3 innings) in 2022.

Though his production took a dip this spring, the Red Sox still elected to take a chance on Carlson, who turns 22 in September. He is the first pitcher taken by Boston on Day 3 and the seventh arm drafted by the club overall.

As is the case with most prospects who are drafted between rounds 11-20, the Red Sox can sign Carlson for up to $150,000 without it counting toward their bonus pool. Carlson does still have eligibility remaining, so he could return to North Carolina for his senior season if he so chooses.
