The Astros placed Murfee (elbow) on the 15-day injured list Thursday, Brian McTaggart of MLB.com reports.

Murfree, whom Houston claimed off waivers from Atlanta earlier this week, isn't expected to be ready to pitch in games until late in the 2024 season -- if at all -- while he completes his recovery from the Tommy John surgery he underwent last July.

The Astros placed Dubin on the 15-day injured list Thursday with a right forearm strain, Brian McTaggart of MLB.com reports.

Dubin didn't pitch in any Grapefruit League games this spring while recovering from what prior reports had described as shoulder inflammation, but the Astros are now labeling his injury as a forearm strain. The right-hander was able to face hitters earlier this week, so he could soon be ready to head out on a minor-league rehab assignment.

The Red Sox selected Rodriguez's contract from Triple-A Worcester on Thursday.

Rodriguez will open the season as the lone lefty in Boston's bullpen. He was limited to just 11 appearances last season due to a hip injury but was healthy and effective this spring.

The Yankees placed Kahnle (shoulder) on the 15-day injured list Thursday.

Kahnle wasn't able to pitch in any Grapefruit League games after a bout with right shoulder inflammation delayed his throwing program over the offseason and put him well behind the Yankees' other pitchers at the start of spring training. The veteran righty should be close to facing hitters if he hasn't already, but he'll likely require multiple minor-league rehab appearances before he's ready to make his 2024 debut with the Yankees.

Pearson will begin the season on the Blue Jays' 26-man roster.

The 27-year-old right-hander still has a big fastball, averaging 97.9 mph over 42.2 big-league innings last season, but Pearson only managed a 4.85 ERA and 43:18 K:BB. With Jordan Romano (elbow) and Erik Swanson (forearm) on the IL to kick off the campaign, there's a spot in the Opening Day bullpen for Pearson, but he hasn't been mentioned by manager John Schneider as a candidate to fill in for Romano in the ninth inning and will likely work in lower-leverage situations.

The White Sox placed Lambert (shoulder) on the 60-day injured list Thursday.

Lambert is recovering from a right rotator cuff strain, and though he's not expected to need surgery to address the injury, he'll still be in store for a prolonged period of rest and rehab before he's ready to pitch again. When healthy last season, Lambert served mostly in a middle-relief role for Chicago, logging three holds and one save to go along with a 5.26 ERA and 1.62 WHIP across 37.2 innings.

The Orioles placed Webb (personal) on the paternity list Thursday.

Webb had been on track to secure a spot in the Orioles' Opening Day bullpen at the conclusion of spring training, but he'll have to wait a bit to make his season debut while he takes some time away from the team to observe the birth of his child. Per MLB rules, Webb can stay on the paternity list for 1-to-3 days before he would have to be added back to the 26-man active roster.

The Orioles recalled Vespi from Triple-A Norfolk on Thursday.

Baltimore initially dismissed Vespi from the competition for a place in the Opening Day bullpen just over a week ago, but a spot opened up Thursday with Jacob Webb (personal) going on the paternity list. Vespi will likely be ticketed for lower-leverage work out of the bullpen for the duration of his stay with Baltimore.

The White Sox designated Peralta for assignment Thursday, Daryl Van Schouwen of the Chicago Sun-Times reports.

After being moved off the 40-man roster, Peralta will now be subject to the waiver process if the White Sox aren't able to find a team willing to trade for the right-handed reliever. Peralta covered 20 innings out of the Chicago bullpen in 2023, logging a 4.05 ERA, 1.50 WHIP and 18:11 K:BB.

The Astros placed Sousa on the 15-day injured list Thursday with left shoulder inflammation, Brian McTaggart of MLB.com reports.

It's not clear when Sousa suffered the injury, but he'll be sidelined for at least the first couple weeks of the season. According to McTaggart, Sousa said his injury is considered nerve-related, and the issue is similar to one that he contended with last year. The left-handed reliever should be in the mix for a spot in the bullpen once he's healthy.
