Triston Casas, battling rib injury, hopes to play 'a good amount of the season'

The Red Sox will be without Triston Casas for a while after a rib issue sent him to the injured list. Boston hasn’t revealed a timeline beyond comments from manager Alex Cora that the young slugger is in for an extended absence.

Casas spoke with reporters Friday, saying that there’s wide variance in the recovery timetable.

“(Doctors) said anywhere from three weeks to six weeks to nine weeks,” the first baseman told the Boston beat via MLB.com’s Ian Browne. “They don’t know. It’s just depending on how my body is feeling. But for right now, I’m still in pain to breathe.”

While the Sox announced the injury as a rib fracture, Casas clarified that the problem is a tear in the cartilage in his midsection. That may not be particularly consequential in terms of his recovery. 

“The way that the doctors kind of explained it to me is that one isn’t better than the other,” Casas said. “[Whether the injury] was a muscle or a bone or cartilage, they’re all similarly timetabled schedules.” 

Despite the uncertainty about the specific timeline, Casas said he’s confident he’ll be able to play “a good amount of the season.”

Bobby Dalbec has taken over at first base. With Dalbec out to an .093/.152/.116 start as his longstanding strikeout issues continue, the Sox could look outside the organization. 

They’ve reportedly considered bringing back C.J. Cron, who was in camp this spring but opted out of a minor league deal after he didn’t make the Opening Day roster. Jared Walsh returned to free agency after being waived by the Rangers, while Garrett Cooper remains in limbo since being designated for assignment by the Cubs.

The Sox will need to piece things together at first base for some time. They’ve gotten better news on the injury front with a few other players, though. 

Vaughn Grissom is expected to wrap up a rehab assignment with Triple-A Worcester this weekend, tweets Alex Speier of the Boston Globe. Their biggest offseason trade pickup has been out all year after straining a hamstring in Spring Training. Grissom could make his Red Sox debut on Tuesday when they open a series against the Giants.

Starter Nick Pivetta isn’t much further behind, as Cora indicated the righty could make a rehab start next week. Pivetta went on the shelf after two starts with the ominous designation of a flexor strain. The team downplayed any long-term concern, however, and it seems he’s on track to return around a month after the injury.

Pivetta was brilliant over his first two appearances, tossing 11 innings of one-run ball with 13 strikeouts and one walk. He’ll be a free agent for the first time at the end of the season, making this a pivotal year for him personally. Depending on his health and the team’s competitive outlook, Pivetta could be one of the top rental starters available around the trade deadline.
