Boston Red Sox left-hander Joely Rodríguez has a Grade 2 oblique strain, manager Alex Cora tells Alex Speier of The Boston Globe. Cora declined to provide a timetable for the southpaw, saying only that he would return “whenever he’s ready.” However, even mild oblique strains usually lead to absences of a few weeks, so Rodríguez seems slated to miss significant time.

Rodríguez, 31, was signed in the offseason to a one-year, $2M deal with a club option for 2024. He spent last year with the New York Mets, posting a 4.47 ERA over 55 appearances. He walked 12% of batters faced but got strikeouts at a 26.4% rate and grounders at a 53.8% clip. It’s possible that he deserved better than that ERA indicates, as his .303 batting average on balls in play and his 63.3% strand rate were both on the unlucky side of average. His 3.23 FIP and 3.54 SIERA suggest he could be better if his luck were to even out.

Unfortunately, he will have to wait a while to test that luck with his new club. Though Cora wouldn’t provide any specifics on the estimated return timeline, there are some recent examples with more details. The Rays, for instance, gave an estimate of six-to-eight weeks when Tyler Glasnow recently suffered his own Grade 2 oblique strain. Every injury is different and it can’t simply be assumed that Rodriguez is looking at the same timeframe, but that can at least provide a rough guideline for what might be on the table here.

The Sox were set to have two lefties in their Opening Day bullpen, with Richard Bleier being the other. There are no other lefty relievers on the 40-man roster, but this news will perhaps open the door for someone else to make the club. Ryan Sherriff was signed to a minor league deal this offseason and could be an option. He was reassigned to minor league camp last week but this new info could perhaps increase his chances of making the club.

If Boston is interested in external additions, the free agent market still features guys like Zack Britton and Ross Detwiler. It’s also possible that some new names will join them on the open market as Opening Day approaches and other clubs make their final roster decisions.
