The Marlins transferred Perez (elbow) from the 15-day injured list to the 60-day IL on Thursday.

The transaction came just a few hours after president of baseball operations Peter Bendix announced that Perez would undergo season-ending Tommy John surgery Monday. By transferring the 20-year-old right-hander to the 60-day IL, the Marlins were able to open up a spot on the 40-man roster for utility player Otto Lopez, whom Miami claimed off waivers from San Francisco on Thursday.

Miley (shoulder) is scheduled to make a rehab start for Triple-A Nashville on Friday, MLB.com reports.

Miley opened the season on the 15-day injured list due to a left shoulder impingement, but he looks on track to be ready to return shortly after he's first eligible for activation April 9. After his shoulder checked out fine Monday following a two-inning simulated game, the veteran lefty will test himself in an uncontrolled setting Friday, and he'll likely increase his innings and pitch counts as well. The Brewers will determine the next step for Miley following the rehab start, but if he fares well Friday, his next outing could come with Milwaukee during its four-game series in Cincinnati at the beginning of next week.

Lively (illness) allowed a hit and struck out three without walking a batter over three scoreless innings in his rehab start versus Triple-A Omaha on Thursday.

Lively began the season on the 15-day injured list, but he was solid in his first rehab appearance. The right-hander was in contention for a rotation spot during spring training prior to coming down with a respiratory virus. It's unclear what his role will be with the major-league team once he's activated -- that will likely depend on Carlos Carrasco's performance as the Guardians' fifth starter and the timeline for the return of Gavin Williams (elbow).

Cobb (hip) said Friday he's been shut down from throwing for a few days due to some flexor tendon inflammation, Susan Slusser of the San Francisco Chronicle reports.

It doesn't appear to be a serious concern since Cobb is expected to resume throwing Monday, but any arm issue is a notable development as he makes his way back from offseason hip surgery. The 36-year-old's return timeline will be pushed back at least a week, which likely means he won't make his season debut until sometime in May.

White Sox general manager Chris Getz said Thursday that he expects Clevinger to make his season debut around May 1, Daryl Van Schouwen of the Chicago Sun-Times reports.

Clevinger's one-year, $3 million contract became official Thursday, and he was optioned to the rookie-level Arizona Complex League to get ramped up before appearing in a major-league game. The White Sox have been using four starters up to this point in the season, and that trend might continue until Clevinger is ready, with the club perhaps opting for some bullpen games when necessary. Clevinger posted a 3.77 ERA, 1.23 WHIP and 110:40 K:BB over 131.1 innings last season.

White Sox general manager Chris Getz revealed Thursday that Nastrini has been battling an illness at Triple-A Charlotte, Scott Merkin of MLB.com reports.

Nastrini made his first start of the season for Charlotte on Wednesday and was bludgeoned for four runs on seven hits and two walks over just three innings, with Getz noting that the right-hander's stuff wasn't sharp, likely as a result of the illness. While Nastrini remains a candidate to start Monday in Cleveland, it's looking like the plan might be to keep him at Charlotte for a while, per James Fegan of SoxMachine.com. The Sox could be leaning toward filling the fifth slot in their rotation with bullpen games until Mike Clevinger is ready, which is expected to happen around May 1.

Gray (hamstring) is still expected to make a rehab start before rejoining the Cardinals' rotation, Jeff Jones of the Belleville News-Democrat reports.

Gray threw a 54-pitch simulated game Wednesday and expressed a desire Thursday for his next appearance to be a start with the big club. However, St. Louis is sticking with its plan to give the veteran right-hander a rehab start first, as Zack Thompson remains on schedule to face the Phillies on Tuesday. Assuming all goes well in Gray's rehab start, he is slated to join the Cards' rotation sometime next weekend in Arizona.

The Blue Jays designated Parsons for assignment Friday.

The right-hander earned a place on Toronto's Opening Day roster but surrendered six runs over five frames in two appearances. Parsons had a 4.52 ERA in 17 starts at Triple-A Buffalo last season, so he seems unlikely to generate significant interest on waivers.

Gipson-Long (groin) will begin a rehab assignment with Low-A Lakeland on Sunday, Evan Petzold of the Detroit Free Press reports.

Gipson-Long has dealt with a left groin strain since early on in spring training and is finally ready to test things out in a game setting. While he could be ready for activation from the 15-day injured list in the next week or two, Gipson-Long seems likely to be sent to Triple-A Toledo at that point rather than being added to the big-league roster.

Gray (0-2) took the loss against Pittsburgh on Thursday, allowing six runs on seven hits and three walks while striking out three batters over 4.1 innings.

Gray gave up seven runs over four innings in a season-opening loss to the Reds last Thursday, and he was only slightly better in his second start, which also ended in defeat. The right-hander at least kept the ball in the park after allowing two homers in his first outing, but he put far too many batters on the basepaths and didn't have his strikeout stuff working to help him get out of trouble. Gray had a modest breakout campaign last year with a career-best 3.91 ERA and his first trip to the All-Star Game, but the underlying metrics weren't strong, and his performance through two games this season justifies his placement on the waiver wire in most standard fantasy leagues.
