There are slight nuances between the two seasons, though Ryan Helsley is the only reliever in this comparison, with 30 saves at the end of the month. He’s joined by Emmanuel Clase (25) as the only two with more than 24.

Relievers cannot control their team’s performance, only the save situations they receive. Those with Andrés Muñoz on their roster do not like seeing Ryne Stanek accrue four saves in June, but he’s pitching through lingering back issues. On the other hand, fantasy managers with Trevor Megill must make alternate plans after the All-Star break with the pending return by Devin Williams.

In leagues with holds as a separate category, some new names are noted on the list, like Ryan Fernandez (STL), Austin Voth (SEA), and Cionel Pérez (BAL). Injuries or expanded leverage roles create opportunities in this format.

For those in leagues with SOLDS (saves plus holds):
