Mason Miller is making waves in the MLB, dominating with a perfect start this season, highlighted by a perfect ninth inning against the Brewers and striking out the side against the Rangers, totaling seven saves with an impressive 17/1 K/BB ratio. Joining him at the top tier is Josh Hader, who has also excelled with eight saves and a 17/3 K/BB ratio. Meanwhile, Andrés Muñoz has posted eight saves with a solid 15/5 K/BB ratio. Injuries are a concern for Emmanuel Clase, who recently blew a save and is dealing with shoulder discomfort.

In Tier 2, Robert Suarez leads with ten saves, while Jeff Hoffman has emerged as a reliable option for the Blue Jays with an 18/1 K/BB ratio. Edwin Díaz shows signs of recovery but has faced some injury issues. Devin Williams, who recently struggled, hopes to regain form while Ryan Helsley has yet to see save chances, raising questions about his future role. Tanner Scott and Jose Alvarado are notable in Tier 3, while Kenley Jansen continues to deliver solid performances. The third and fourth-tier closers show varying degrees of reliability, with plenty of options to monitor as the season progresses.

With the season in full swing, the dynamics of bullpens are shifting rapidly, making it crucial for fantasy players to stay updated on the latest performances and injury reports to maximize their roster potential.
