Red Sox designate John Schreiber for assignment, option former first-round pick Michael Chavis

The Red Sox announced a series of roster moves Tuesday as they get closer to solidifying their Opening Day squad. Boston reinstated outfielder Franchy Cordero from the COVID-19 injured list and designated right-hander John Schreiber for assignment to open a spot on the 40-man roster. The Sox also optioned infielder Michael Chavis and right-hander Colten Brewer to their alternate training site in Worcester.

Schreiber, 27, was claimed off waivers out of the Tigers organization back in February. He didn’t get a long look this spring, allowing a pair of runs on five hits and a walk in 1 1/3 innings through two appearances before being optioned two weeks ago. He’s spent time with the Tigers over the past two seasons as well, logging a 6.28 ERA in 28 2/3 frames at the big-league level.

Obviously, those results aren’t much to look at, but Schreiber has a career 1.99 ERA in the minors — including a 2.28 mark in 59 1/3 innings of work at Triple-A. The sidearmer punched out 25.6% of opponents in the Majors against a tidy 6.2% walk rate, and right-handed batters managed only a lowly .192/.270/.311 output against him during the 2019 season. The Sox surely hope he’ll clear waivers and give them a depth candidate.

The 25-year-old Chavis is a former first-round pick who opened some eyes early in his debut campaign with the Sox but has struggled since. He hit .212/.259/.377 in 158 trips to the plate last year, and while he did belt six long balls this spring, his overall offensive game wasn’t without red flags. Chavis batted .250/.292/.600 in 65 plate appearances, striking out 20 times (30.7%) against just two walks (3.1%). High strikeout and marginal walk rates have persisted throughout Chavis’ career to date, so the Sox will send him down to continue to work on his approach.

With Chavis being sent down to begin the season, that likely means fellow infielder Christian Arroyo will make the club. The former top prospect is out of minor-league options, which may have given him a leg up in the race, but he’s turned in a respectable .269/.309/.462 batting line with a trio of homers himself in 55 plate appearances.

The 28-year-old Brewer, meanwhile, has tallied 80 1/3 innings of relief for the Sox over the past two seasons, but he struggled in 2020 and saw his troubles continue in Spring Training. Brewer notched a respectable 4.12 ERA in 54 1/3 innings back in 2019, but he was tagged for 16 earned runs in 25 2/3 frames last year (5.61 ERA) and served up seven runs in 6 1/3 innings this spring.

The Sox also received some concerning news on righty Ryan Braiser, who is headed for an MRI after straining his left calf while working in a “B” game Monday (via Chris Cotillo of MassLive.com). Brasier has been slowed in camp by a fractured pinkie but looked to be trending toward a return early in the season. The MRI will tell how substantial a setback this will be, but Brasier was on crutches this morning, and manager Alex Cora told reporters that the situation “doesn’t look too promising.”
