Miami Marlins left-handed pitcher Ryan Weathers (forearm) is set to throw a pitch design on Tuesday. Weathers has been sidelined since March due to a forearm strain. He was placed on the 15-day injured list on March 27. However, he quickly began a throwing progression and was able to make his first minor-league rehab start on April 28. In his first rehab outing with Low-A Jupiter, Weathers was sharp and tossed three no-hit innings. He struck out six batters. However, in his second outing, he was moved up to Triple-A but took a step back and allowed two runs across 2 2/3 innings of work. Fantasy managers should keep a close eye on his status, as he could be cleared to make his 2025 season debut sometime next week. When he does get cleared to return, he would be worth adding in all standard formats after posting a 3.63 ERA with a 1.18 WHIP across 86 2/3 innings last summer.

Miami Marlins starting pitcher Eury Perez (elbow) is set to make another rehab outing with Low-A Jupiter on Tuesday. Perez is currently on the 60-day injured list and working his way back from Tommy John surgery. The team noted that the budding ace is scheduled to make at least eight rehab outings before being in contention to return to the big leagues. So far, the former top prospect has made two rehab outings with Low-A. Across two 2/3 innings of work, Perez has allowed just one hit and held a 4:1 K:BB. He has not allowed a run. The 22-year-old made his MLB debut during the 2023 campaign and flashed high upside as he held a 3.15 ERA with a 1.13 WHIP. He struck out 108 batters and generated an elite .208 xBA. He is worth monitoring as he could be a must-start option in the second half of the campaign.

Chicago Cubs manager Craig Counsell said that right-handed itching prospect Cade Horton is an option to take left-hander Shota Imanaga's (hamstring) place in the big-league starting rotation after the team placed Imanaga on the 15-day injured list on Monday. In addition to Horton, veteran right-hander Chris Flexen is stretched out in a long-relief role and is another option, although he isn't nearly as intriguing for fantasy purposes. Horton was the former seventh overall pick in 2022 out of Oklahoma and is considered the club's No. 2 prospect, per MLB Pipeline. While Flexen might have the upper hand to make a start this weekend against the New York Mets because he's on the 40-man roster, Horton represents the much better speculative waiver-wire pickup. The 23-year-old has posted a strong 1.24 ERA, 0.86 WHIP and 33:13 K:BB in 29 innings for Triple-A Iowa to begin the 2025 season.

Washington Nationals manager Dave Martinez said on Monday that left-hander MacKenzie Gore (ankle) is dealing with a sore ankle, but he's feeling a lot better. Gore slipped on a wet mound during his outing on Sunday against the Cincinnati Reds in the fifth inning, but he appears to have avoided a serious injury and should be able to make his next scheduled start this Sunday versus the St. Louis Cardinals. The 26-year-old southpaw and former third overall pick by the San Diego Padres in 2017 picked up a no-decision on Sunday against the Reds by allowing one earned run on four hits while walking four and striking out nine in five innings of work. Gore has looked good in his third year with the Nats and has posted a career-best 3.33 ERA (2.72 FIP) and 1.15 WHIP with a league-high 68 K's and 13 walks in eight starts over 46 innings. Start Gore on Sunday if he's cleared.

Miami Marlins outfielder Derek Hill (wrist) is going through full baseball activities. Hill has been sidelined since April with a left wrist sprain. Hill was officially shifted to the 10-day injured list on April 18. Fantasy managers should continue monitoring his progression, but it appears Hill is nearing a rehab assignment. Given the time he missed, Hill may only need a brief assignment before returning to Miami. Before his injury, Hill held a .167/.239/.286 slash line with one home run and three stolen bases. Under the hood, Hill generated a modest .224 xBA and a .289 xwOBA but placed in the 97th percentile in sprint speed. When he does return, he should compete for an everyday role in center field alongside Dane Myers and Jesus Sanchez.
