The Red Sox announced a series of roster moves this evening, headlined by the club placing outfielder Tyler O’Neill on the 10-day injured list due to a left leg infection. The move is retroactive to August 4. Replacing O’Neill on the active roster is infielder Enmanuel Valdez, who has been recalled to the big league roster, and the Red Sox also activated right-hander Chris Martin from the 15-day IL. Lefty Cam Booser was optioned to Triple-A to make room for Martin.
O’Neill, 29, was acquired from the Cardinals over the offseason and has enjoyed an excellent campaign during his first season in Boston. In 342 trips to the plate this season, the 29-year-old has slashed an excellent .268/.357/.544 (142 wRC+) with 16 doubles and 22 homers. While he’s striking out at a hefty 31.9% clip, he’s paired those strong power numbers with a solid 11.1% walk rate that has given him a more well-rounded profile than he flashed in his career-best 2021 campaign when he crushed 34 homers and posted a 143 wRC+ but walked at a clip of just 7.1%.
The slugger’s performance this year seems likely to line the pending free agent up for hefty raise in free agency this winter, although one red flag for O’Neill has been his frequent trips to the shelf. After suffering hamstring, back, foot, and shoulder injuries during his final two seasons with St. Louis, he’s now made three trips to the shelf with the Red Sox this year: once for a concussion in April, once due to knee inflammation in May, and now today’s most recent ailment that manager Alex Cora described to reporters (including Pete Abraham of The Boston Globe) as a worsening infection on his left leg that has caused swelling.
The silver lining in O’Neill’s repeated trips to the IL this year is that they’ve all been fairly short-lived, and Cora indicated that this one should be more of the same as he’s likely to be activated once eligible to return next week. In the meantime, the Red Sox figure to turn to some combination of Jarren Duran, Wilyer Abreu, Ceddanne Rafaela, and Rob Refsnyder in the outfield. With Rafaela frequenting the outfield in recent days, Valdez should help to shore up the club’s middle infield mix alongside David Hamilton, Nick Sogard, and Romy Gonzalez. The 25-year-old enjoyed a strong rookie season in 2023 but has taken a step back this year with a .226/.282/.402 slash line in 182 trips to the plate at the big league level.
As for Martin, the right-hander’s return to action is welcome news for a beleaguered Red Sox bullpen that has been second-worst in the majors since the start of July, ahead of only the White Sox. The 38-year-old veteran sports a solid 3.42 ERA with a matching 3.40 FIP in 26 1/3 innings of work this year and is coming off an even better season in 2023 where he dominated to the tune of an eye-popping 1.05 ERA in 55 appearances. Adding Martin to the late-inning mix to be the primary set-up man for closer Kenley Jansen should further shore up a bullpen that got reinforcements in the form of Lucas Sims and Luis Garcia prior to the trade deadline. He’ll take the roster spot of Booser, who heads to Triple-A to become the club’s top depth option with an excellent 2.77 ERA and 2.99 FIP in 39 innings of work this year.
While the bullpen will hopefully be revitalized by the return of Martin, Cora suggested to reporters today (including Abraham) that the Red Sox intend to skip right-hander Nick Pivetta’s next start. While the veteran righty doesn’t appear to be injured, Cora indicated that he’s “not responding well” coming out of his last start and that the club had some concerns about a dip in his velocity. With a day off scheduled tomorrow, the Red Sox will be able to utilize the rest of their rotation on regular rest without needing to call up another arm to take the spot on Pivetta. The righty has a middling 4.44 ERA through 18 starts this year thanks primarily due to a trio of brutal outings his last three times out that have seen him surrender 13 runs (12 earned) in 14 innings of work while serving up six home runs.
