Former Red Sox outfield prospect Marcus Wilson took to social media on Sunday to announce his retirement from professional baseball.

As part of a heartfelt Instagram post, Wilson gave “a special thanks to a select few from the Red Sox” as well as his coaches from the Diamondbacks and Mariners organizations. He also showed gratitude towards his mother, wife, and daughter before indicating that he was going to shift his focus towards a career in mixed martial arts.

“I’ve had a lot of time to digest everything that’s been going on and I feel good about my decision so going forward if you ever wanna hit me up don’t be weird about it I’m really fine lol!” Wilson wrote. “I’m excited for my new journey I’m going to be taking up martial arts and ever since 2020. I’ve been extremely fascinated with the sport and finally excited to get to do martial arts! Peace and love everybody. Thank you.”

Wilson, 27, was originally selected by the Diamondbacks with the 69th overall pick in the 2014 amateur draft out of Junipero Serra High School in Gardena, Calif. The Los Angeles-area native forwent his commitment to Arizona State University by signing with the club for $1 million that summer.

As he continued to climb up the minor-league ladder, Wilson established himself as one of the better outfield prospects in Arizona’s farm system. He was then traded by the Diamondbacks to the Red Sox for catcher Blake Swihart in April 2019.

Wilson bounced between then-High-A Salem and Double-A Portland in his first season as a member of the Red Sox organization, but he ended the year on a strong note with the Sea Dogs and was added to Boston’s 40-man roster that November in order to receive protection from the Rule 5 Draft.

Unfortunately, Wilson did not play any affiliated ball in 2020 as a result of the COVID-19 pandemic wiping out the minor-league season. He instead spent the final three or so weeks of the 2020 campaign at the Sox’ alternate training site in Pawtucket and then made the jump to Triple-A Worcester the following spring.

In his first stint with the WooSox, Wilson batted .242/.370/.452 with 10 home runs and 30 RBIs over 64 games (265 plate appearances). Despite putting up those solid numbers, the right-handed hitting infielder was designated for assignment by the Red Sox in the wake of the July trade deadline. He was then claimed off waivers by the Mariners, but spent the rest of the 2021 season with Seattle’s Triple-A affiliate in Tacoma before yet again losing his spot on a 40-man roster that October.

Wilson remained with the Mariners through the winter and returned to Tacoma for the start of the 2022 season. After clubbing 12 homers and posting an .806 OPS in 59 games (238 plate appearances) for the Rainiers, Wilson earned his first big-league call-up in late June. He made his major-league debut against the Orioles at T-Mobile Park on June 29 and drew a walk in his first career plate appearance after pinch-hitting for Sam Haggerty in the eighth inning of a 9-3 win.

Wilson appeared in a total of three games for the Mariners, going 1-for-5 with a single, a run scored, that one walk, and four strikeouts while seeing playing time in both right and center field. He was then sent back down to Tacoma in early July before being designated for assignment and outrighted off Seattle’s 40-man roster, which cleared the way for him to elect free agency at the end of the year.

Last February, Wilson returned to the Red Sox on a minor-league contract for the 2023 season. Serving as upper-level outfield depth, Wilson was limited to just 37 games with the WooSox and spent much of the first half of the year on the development list before being released. He had not signed with another team prior to announcing that he was hanging up the cleats for good on Sunday.

All told, Wilson slashed .248/.351/.406 with 141 doubles, 21 triples, 71 home runs, 327 RBIs, 394 runs scored, 114 stolen bases, 380 walks, and 850 strikeouts while logging starts at all three outfeed spots in 729 career minor-league games (2,941 plate appearances). That includes parts of four seasons (2019-2021, 2023) with the Red Sox in which he peaked as the No. 20 prospect in the system in Oct. 2019, per SoxProspects.com rankings history.
