Boston Red Sox right-hander Brayan Bello (shoulder) is scheduled to make a minor-league rehab start for the Triple-A Worcester WooSox on Tuesday, according to MassLive's Christopher Smith. Bello suffered a right-shoulder strain right at the start of spring training in mid-February and was unable to pitch at all in the Grapefruit League as a result. The 25-year-old is expected to make at least two rehab appearances for Worcester, and barring any setbacks, he could be ready to come off the 15-day injured list when he's first eligible on Friday, April 11. When the BoSox do clear Bello to make his 2025 debut and return to the starting rotation, left-hander Sean Newcomb will likely be the odd-man out of Boston's rotation. Bello has so far been inconsistent and has struggled with keeping the ball in the yard and with his command.

Cincinnati Reds right-handed reliever Alexis Diaz (hamstring) threw live batting practice on Tuesday, according to The Cincinnati Enquirer's Charlie Goldsmith. Diaz displayed terrible control in spring training and then injured his hamstring, which landed him on the 15-day injured to begin the 2025 regular season. The 28-year-old is already throwing to live hitters and is eligible to come off the IL on April 8, but it's unclear if he'll be ready by then or if the Reds are even comfortable throwing him back into their big-league bullpen by then. After recording the team's first save chance early on, right-hander Emilio Pagan is manager Terry Francona's clear preferred choice for the ninth inning with Diaz sidelined, but Tony Santillan is also a very trusted weapon in high-leverage situations. It's quite possible that Diaz is eased into lower-leverage situations out of the 'pen in Cincy when he does make his season debut.

The Philadelphia Phillies claimed right-hander Brett de Geus off waivers from the Miami Marlins on Tuesday and optioned him to Triple-A Lehigh Valley, according to MLB.com's Todd Zolecki. de Geus spent the 2024 season with three different teams -- the Seattle Mariners, Marlins and Toronto Blue Jays -- and will now head to his fourth different team since January. The 27-year-old will merely be organizational relief depth for the Phillies for the time being and isn't on the fantasy radar at all. He was originally a 33rd-round pick by the Los Angeles Dodgers in 2017 out of Cabrillo College. de Geus made his major-league debut with the Texas Rangers in 2021 and also pitched with the Arizona Diamondbacks that year. In parts of two big-league seasons with five different teams, he has a 7.48 ERA and 1.71 WHIP in 61 1/3 relief frames.

Milwaukee Brewers right-handed reliever Nick Mears (illness) is starting his minor-league rehab assignment with Triple-A Nashville on Tuesday, the team announced. Mears only appeared in three spring training games due to an illness that landed him on the 15-day injured list to begin the 2025 regular season. He's eligible to come off the IL on April 8, but it's unclear if he'll start the year at Nashville or with the Brewers in their bullpen. The 28-year-old hard-throwing righty has intriguing swing-and-miss stuff but has been inconsistent in his brief time in the big leagues with three different teams because of his inability to locate effectively in the strike zone. Mears has the stuff to work in a high-leverage relief role for the Brew Crew, but fantasy managers can avoid him for now with his 5.20 ERA and 1.53 WHIP in 107 1/3 career innings.

Despite landing on the injured list on Monday, Milwaukee Brewers right-hander Aaron Civale (hamstring) was able to play catch on Tuesday after his MRI exam revealed only a mild strain of his hamstring. While nothing is set in stone just yet, this news means that Civale should have a chance to return from the IL when he's eligible on Tuesday, April 15. If at all possible, the Brewers would love to have him back in their injury-depleted starting rotation, too. Civale made it only three innings in his first start of 2025 in the Bronx against the New York Yankees on March 30, allowing five earned runs on four hits (three homers allowed) while walking one and striking out two. If the 29-year-old hurler continues to improve quickly, he could even forego a minor-league rehab assignment. Injury aside, Civale has limited fantasy upside due to lack of strikeout stuff.
