The Red Sox signed free-agent right-hander Morgan McSweeney to a minor league contract on Wednesday. He struggled in his organizational debut for Double-A Portland, surrendering five earned runs on five hits (including one home run), no walks, and three strikeouts over two innings of relief.
McSweeney returns to affiliated ball after spending the first part of the 2026 season abroad in the Chinese Professional Baseball League. The 28-year-old made nine appearances (eight starts) for the Rakuten Monkeys, posting a 5.08 ERA with 21 strikeouts to 24 walks over 44 1/3 innings before being released in late June.
A Hudson, Mass. native and Worcester Academy product, McSweeney was originally selected by the Orioles in the 17th round (498th overall) of the 2019 draft out of Wake Forest. The righty received a $125,000 signing bonus and spent five-plus years in the organization without reaching the majors, instead peaking at Triple-A Norfolk before he was cut loose by Baltimore in July 2024.
McSweeney spent the next 11 months between Gastonia and Staten Island of the independent Atlantic League before his contract was purchased by the Marlins last June. From there, he pitched to a 2.21 ERA with 42 strikeouts to 23 walks across 13 appearances (12 starts) spanning 61 innings for Triple-A Jacksonville to close out his 2025 campaign. He elected free agency in November and signed with Rakuten in December.
Following Wednesday’s rough outing in Portland, McSweeney now owns a lifetime 3.77 ERA with 237 strikeouts to 123 walks over 151 career appearances (12 starts) and 241 1/3 innings in the minors. Stuff-wise, the 6-foot-4, 210-pound hurler features a lower-90s fastball that has reached 93 mph, a cutter, a slider, a changeup, a curveball, and a sinker.
McSweeney, who turns 29 next month, will presumably provide Boston with additional upper-minors pitching depth between Portland and Triple-A Worcester down the stretch this season. He is the third arm the Red Sox have brought in via minor-league contract in the last week, joining veteran righty John Brebbia and former Yankees farmhand Aaron Nixon.
