Injuries & Roster Moves: Sox add RHP Ríos

June 14th, 2021

Keep track of the Red Sox recent transactions and injury updates throughout the season.


June 14: Acquired RHP Yacksel Ríos for cash considerations
Ríos, who was designated for assignment by the Mariners on Friday, joins his fourth MLB team in his fifth season. The 27-year-old (who turns 28 on June 27) allowed one run in each of his three one-inning relief appearances for Seattle this year. Since 2019, he has allowed 20 runs (17 earned) in 20 big league innings.

June 14: Promoted INF Michael Chavis from Triple-A Worcester
Chavis was previously optioned to Worcester after compiling a .758 OPS over 11 games with the Red Sox. In Triple-A, he posted a .737 OPS in 19 games, but he’s been hot lately: He’s 9-for-19 (.474) with a double and three home runs in his past five games.

June 14: Designate RHP Ryan Weber for assignment
Weber’s contract had been selected from Triple-A Worcester on Sunday, and the 30-year-old proceeded to allow 11 earned runs over 5 2/3 innings in a tough loss. In 89 1/3 career innings with Boston over the past three seasons, Weber posted a 5.54 ERA.

June 13: Designate RHP Brandon Brennan for assignment
Saturday’s three scoreless innings against Toronto comprised the entirety of Brennan’s work with the big league club. He has also pitched to a 2.16 ERA in 8 1/3 innings with Triple-A Worcester during his first season with the Red Sox organization (and 10th pro season overall).


Day to day

60-day IL

LHP (Tommy John surgery)
Expected return: August
Three days after throwing off Fenway Park’s bullpen mound, Sale fired a side session on the main diamond on June 11. The Red Sox are so encouraged by the way he looks that they’re actually trying to contain their enthusiasm.

“We need to try not to get too excited,” said manager Alex Cora. “It was that good. The energy and the quality of the pitches, the tempo -- he looked really good. He said that’s the best he’s felt throughout the process. You guys saw it, having his peers around him means a lot to him, and I think pitching on that mound means a lot. Obviously with technology, that helps us with information, but being on a big league mound, being a big league player, that means a lot to him. He doesn’t take that for granted, and it was a really good one.” (Last updated: June 11)

RHP (concussion, left calf strain)
Expected return: July
The Red Sox had good news on Brasier. One day after he was struck on the right side of his face by a line drive in a simulated game, the reliever was released from the hospital and resting comfortably at his apartment in Fort Myers, Fla. Brasier has a concussion, but it appears he has otherwise dodged any additional head injuries.

Before that scary incident, he was in the final stages of recovering from a left calf strain suffered at the end of Spring Training. Brasier's sim game on Friday was expected to be his last step before going on a Minor League rehab assignment. Now, he will have to go through concussion protocol and additional recovery before the Red Sox clear him to return to baseball activities. (Last updated: June 5)

Minor League IL

RHP (Sore right flexor, right arm)
Expected return: July
Houck, Boston’s No. 6 prospect, was shut down a month ago with a flexor injury in his right arm. He is starting to build back up. According to Red Sox manager Alex Cora, Houck recently threw an “up and down” bullpen session, meaning he pitched one inning, sat for a bit, then came back out for another. The next step will be to face hitters. He will probably do that multiple times before getting back into games. Houck is important to the Red Sox because he is their top depth option if one of their starters gets injured. (Last updated: June 12)
