MLB Network's Jon Morosi mentions that Philadelphia Phillies left-handed reliever Tim Mayza has been excellent so far this year when discussing the direction that the team might go at the back end of the bullpen with star closer Jhoan Duran (oblique) expected to be out two to three weeks with an oblique injury. Right-hander Brad Keller is "probably" going to be the guy that gets the next save chance in Philly, but Mayza, Jose Alvarado, and Orion Kerkering could end up forming some sort of committee for manager Rob Thomson. Mayza could get the nod if it's a lefty-heavy inning for the opponent in the ninth inning. The 34-year-old veteran only has four saves in his big-league career in eight-plus seasons, but he currently has a 3.00 ERA with 12 strikeouts and four walks in 12 relief innings pitched in 2026. In deeper fantasy leagues where managers are desperate for saves, they may want to consider a waiver-wire pickup of Mayza in the short term.

Tampa Bay Rays manager Kevin Cash said that right-handed reliever Edwin Uceta (shoulder) has a right-shoulder strain, which is a new injury from the discomfort that initially landed him on the 15-day injured list to begin the 2026 regular season, according to Marc Topkin of the Tampa Bay Times. Uceta will be shut down from throwing for two to three weeks and will then have to build back up, so fantasy managers shouldn't expect him to make his season debut for the Rays for a while. It's a tough break for those who have been stashing the 28-year-old in fantasy leagues in hopes that he'll become the team's primary closer when he's fully healthy. In a best-case scenario, Uceta may not rejoin Tampa's bullpen until mid-to-late May. He's still worth holding onto in fantasy leagues, though, if you have an available IL spot. Uceta has been pretty solid for the Rays the last two seasons and was one of only five relievers in 2025 to have over 100 strikeouts. Until further notice, Bryan Baker is the reliever to roster for saves in Tampa.

According to Jon Morosi of the MLB Network, Philadelphia Phillies relief pitcher Brad Keller is projected to receive the first save situation in the current bullpen. The Phillies have several relievers on the injured list, with primary closer Jhoan Duran (oblique) being the most notable name. Through the early going in the regular season, Keller has operated as the top setup man, tallying four saves over his first eight appearances while posting a 4.70 ERA with an 8:2 K:BB. On April 18, Keller was deployed in the ninth inning (in a non-save situation), which suggests the Phillies trust him in the final frame. Last summer, Keller was a reliable setup option for the Cubs, earning 26 holds and chipping in three saves with a strong 2.07 ERA. He should be viewed as a top option for saves on the waiver wire ahead of Week 4.

The Los Angeles Dodgers have placed closer Edwin Diaz (elbow) on the 15-day injured list with loose bodies in his right elbow. In a corresponding move, the Dodgers are promoting Jake Eder from Oklahoma City. Diaz was dealing with velocity concerns over the past two weeks and will now miss at least the next 15 days on the injured list. In his most recent outing on Sunday, Diaz failed to record an out as he surrendered three hits, three runs, and a walk to the Colorado Rockies. In this appearance, Diaz's fastball sat at 95.4 mph compared to the 97.3 mph it averaged last summer. While Diaz was enjoying a strong start to his Dodger career, earning four saves over his first five appearances with a 1.80 ERA, the right-hander is now in serious danger of missing extended time. While he remains sidelined, Alex Vesia and Tanner Scott figure to see the bulk of the save opportunities, with Vesia projected to operate as the lead option, given his recent usage.
