10:38PM: There are “no red flags as far as structure” to Martin’s shoulder, manager Alex Cora told MassLive.com’s Chris Cotillo and other reporters. The Red Sox are hopeful that Martin might be facing just a minimal 15-day absence.
12:12PM: The Red Sox announced a series of roster moves this afternoon, placing right-hander Chris Martin on the 15-day IL (retroactive to Thursday) with right shoulder inflammation. To replace Martin on the active roster, the club has selected the contract of right-hander Jake Faria from Triple-A. To clear a 40-man roster spot for Faria, the club has transferred right-hander Wyatt Mills, who is suffering from right elbow inflammation, to the 60-day IL.
Martin debuted with the Rockies back in 2014, but struggled to a 6.19 ERA in the first two seasons of his big league career before departing for Japan, where he dominated in the NPB to the tune of a 1.12 ERA in 88 1/3 innings of work. That performance earned him another shot in the big leagues, where he’s been a successful setup man ever since. Since the start of the 2018 season, Martin has posted a 3.41 ERA (135 ERA+) with a 3.06 FIP in 221 2/3 innings of work.
While his top-level run prevention numbers last season left something to be desired in the beginning of his season as a member of the Cubs, his 4.31 ERA in his 31 1/3 innings as a Cub were inflated by a .393 BABIP. Underlying metrics saw him strike out 30.1% of batters while walking just 3%, leaving him with a 3.01 FIP during his time with in Chicago. Those strong underlying stats manifested in a dominant stretch run following a midseason trade to the Dodgers: in 24 2/3 innings in Dodger blue, Martin posted a fantastic 1.46 ERA with a microscopic 1.13 FIP.
That left Martin entering free agency with a 3.05 ERA, 2.18 FIP, 32.9% strikeout rate, and 2.2% walk rate in 2022. Those numbers were strong enough to net him a two-year, $17.5MM deal with the Red Sox, where he figured to slot into the back of the Boston bullpen alongside fellow offseason signing Kenley Jansen. Those plans will now be put on hold for awhile, however, with Martin headed to the IL. No timetable has been announced for his return. While Martin is on the IL, John Schreiber and Josh Winckowski figure to handle late-inning duties alongside Jansen.
With Martin on the shelf, the Red Sox turn to Faria. The 29 year old did not pitch in the majors in 2022, though he has a career 4.70 ERA (90 ERA+) with a matching 4.74 FIP in 203 big league innings with a 20.9% strikeout rate a 10% walk rate. After spending 2022 in the minors with the Twins, where he struggled to a 7.48 ERA in 43 1/3 innings of work, Faria signed a minor league deal with the Red Sox back in February.
Mills was acquired from the Royals in a trade this winter, but was shut down last month with elbow inflammation. He has a career 6.21 ERA in 42 big league innings, albeit with a much more palatable 3.84 FIP.
