Los Angeles Dodgers relief pitcher Blake Treinen got the call in the ninth inning to seal the victory against the Detroit Tigers on Thursday. Treinen allowed a leadoff single to second baseman Gleyber Torres. He then struck out Riley Greene for his first out. However, he then walked Spencer Torkelson. Treinen was able to bounce back and retire the next two batters, one with a strikeout to seal the victory. Earlier in the offseason, Dodgers manager Dave Roberts expressed that Tanner Scott would be the primary closer. However, through their first three games, Scott has earned just one save, with Alex Vesia and Treinen earning the others. In Thursday's contest, Scott entered the game in the eighth inning. Fantasy managers should continue to monitor how the Dodgers deploy their high-leverage relievers. However, given the elite offensive firepower in Los Angeles, both Scott and Treinen could have value in standard formats, even if they share save opportunities.

St. Louis Cardinals right-handed pitcher Ryan Helsley tossed a shutout inning en route to earning the save on Opening Day in their victory against the Minnesota Twins. Helsley struck out the first two batters he saw before allowing a two-out double to outfielder Harrison Bader. However, Helsley returned to form and struck out Matt Wallner to get the final out. Last season, Helsley was one of the most valuable relief pitchers in fantasy as he tallied 49 saves, the most in the National League. Across 66 1/3 innings, he posted a 2.04 ERA with a 1.10 WHIP. He tallied 79 punchouts but held a modest 8.6 percent walk rate. Helsley also generated an elite 3.7 percent barrel rate and a 36,1 percent whiff rate. Even though the Cardinals may not be competing for the NL Central title this season, Helsley should see every save opportunity in St. Louis and remains a must-start option in all formats.

Cleveland Guardians outfield prospect Johnathan Rodriguez was promoted to the MLB roster prior to Thursday's contest. Rodriguez was initially optioned to Triple-A Columbus but returned to the majors once Cleveland placed several pitchers on the injured list. During spring training, the 25-year-old posted a .217/.375/.391 slash line with a long ball. He received a brief taste of the majors last season as he tallied four hits (one extra-base hit) across 13 contests. He tallied five RBI and held a 9:14 BB:K. Rodriguez was very productive at Triple-A last summer as he posted a strong .301/.390/.540 slash line with 18 doubles and 29 round-trippers. Fantasy managers should expect Rodriguez to serve as a depth outfielder and could eventually see playing time over Jhonkensy Noel. However, given his low projected playing time at the moment, he should only be rostered in deeper AL-only leagues as a stash option.

Sean McAdam of Masslive.com reports that Boston Red Sox outfielder Masataka Yoshida (shoulder) traveled back to Boston for consultation on the back injury he's dealing with. McAdam notes that he'll stay there for shoulder rehab until he is game-ready. The 31-year-old was never expected to be ready for the Red Sox opener, though it shouldn't be long before he rejoins the team. The lefty hit a respectable .286 this spring (10-for-35) in 11 appearances but was having issues throwing the ball while recovering from surgery to fix a torn labrum in his right shoulder last October. He was far superior against right-handed pitching in 2024.

The Arizona Diamondbacks have placed pitcher Kendall Graveman (back) on the 15-day injured list (retroactive to March 24). Graveman has been dealing with back tightness this spring after missing the entirety of the 2024 season due to surgery on his shoulder. The veteran right-hander is set to resume throwing off a mound next week, but he's behind in his buildup, considering he didn't make any appearances this spring. He's been a useful bullpen arm over the past few seasons, registering an ERA of 3.18 or under from 2021-2023. It will be a little bit before Graveman returns to the mound.
