The Red Sox announced this morning that the club has recalled right-hander Naoyuki Uwasawa, whose first appearance with Boston will be his big league debut. Left-hander Joely Rodriguez was designated for assignment to make room for Uwasawa on the club’s active roster. Uwasawa, 30, signed a minor league split contract with the Rays back in January but was traded to the Red Sox after he activated an assignment clause in his deal that obligated Tampa to deal him to any club willing to offer him a 40-man roster spot. Boston indeed added Uwasawa to their 40-man, though he began the season at Triple ..read more

5:24pm: The deal is now official, as noted by Alex Speier of The Boston Globe. The Red Sox transferred Casas to the 60-day injured list to make room for Cooper on the 40-man roster. 2:39pm: The Red Sox have acquired first baseman Garrett Cooper, the Miami Herald’s Craig Mish writes (via X).  MassLive.com’s Chris Cotillo reported (X link) earlier this afternoon that the Sox were “closing in on” a deal for Cooper’s services, and Cotillo and Sean McAdam report that the Cubs will receive cash considerations in return. Chicago designated Cooper for assignment earlier this week, and today’s tra ..read more

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 yesterday, 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 (link 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 ..read more

The Red Sox have agreed to a minor league contract with right-hander Sal Romano, per the team’s transaction log at MLB.com. He’ll head to Triple-A Worcester. Romano, 30, hasn’t pitched in the big leagues since the 2021 season but joins the Red Sox with 275 1/3 frames of MLB experience to his credit. He had a nice debut campaign with the Reds back in 2017, making 16 starts and pitching to a respectable 4.45 ERA in 87 innings that year. The 6’5″, 250-pound righty fanned 19% of his opponents against a somewhat elevated 9.4% walk rate and also kept the ball on the ground at a 50.4% clip. It was ha ..read more

The Red Sox lost first baseman Triston Casas for a yet-to-be-determined but significant period of time yesterday, as the 24-year-old slugger was diagnosed with a left rib fracture. Manager Alex Cora said at the time that Bobby Dalbec would get the bulk of playing time at first base in lieu of Casas, but it seems the Sox are also mulling the possibility of going outside the organization. Chris Cotillo of MassLive.com reports that Boston has had some initial talks about bringing veteran C.J. Cron back to the organization. Cron, 34, was with the Sox during spring training but was granted his rele ..read more

Red Sox skipper Álex Cora acknowledged over the weekend that there was concern about a potentially “lengthy absence” for first baseman Triston Casas following a rib injury, and it now seems those fears were warranted. Cora announced to the Red Sox beat that an MRI revealed a left rib fracture for Casas (X link via MassLive.com’s Chris Cotillo), adding that the slugger is expected to be sidelined for “a while.” Cora didn’t delve into specifics but noted that Bobby Dalbec will pick up the bulk of playing time at first base in his absence. The news is obviously rough for the Red Sox, as Casas has ..read more

The Diamondbacks announced a pair of acquisitions Tuesday: left-hander Joe Jacques was claimed off waivers from the Red Sox, while infielder Sergio Alcantara was acquired from the Pirates in exchange for cash. Both players are headed to Triple-A Reno. Jacques is on the 40-man roster, but Alcantara — who’d signed a minor league deal with Pittsburgh — is not. Arizona’s 40-man roster is now at capacity. Jacques, 29, appeared in just one game for the Red Sox this season, allowing a run in 1 2/3 innings. He yielded three hits but didn’t issue a walk and also picked up a pair of strikeouts. Dating b ..read more

The Red Sox have been without second baseman Vaughn Grissom for all of the 2024 season to this point after the 23-year-old missed Spring Training due to a groin strain. Early expectations put Grissom’s timetable for return in the range of mid- to late-April, though Katie Morrison-O’Day of Masslive noted yesterday that Grissom and the club plan to take his rehab slowly as he looks to build up for the season. Per Morrison-O’Day, Grissom has mostly played DH throughout his rehab assignment to this point but has ramped up his time at second base in recent days, including playing all seven innings ..read more

Red Sox first baseman Triston Casas exited today’s game against the Pirates in the first inning due to what the club has termed left rib discomfort. As noted by Chris Cotillo of MassLive, manager Alex Cora indicated to reporters after the game that he was “concerned” about Casas’s injury and that the first baseman had left the ballpark to undergo further testing. While it’s not entirely clear how serious Casas’s injury is, it appears the club is at least preparing for the possibility that an IL stint will be required as Cotillo also reports that journeyman catcher Tyler Heineman is set to join ..read more

Nick Pivetta threw a bullpen session today, and Red Sox manager Alex Cora gave reporters (including MassLive.com’s Chris Cotillo) a rough timeline of when the righty might return from the right flexor strain that sent Pivetta to the 15-day injured list on April 6.  Cora outlined that Pivetta is around 10 days away from facing live hitters and then will get probably two minor league rehab starts, so if all goes well, Pivetta should be back in Boston’s rotation by around the middle of May. There was some initial hope that Pivetta could miss just the minimum 15 days when he first went on the ..read more
