Mets' Closer Diaz Dominates with Back-to-Back Reliever of the Month Awards
4 Aug
Summary
- Mets' closer Edwin Diaz named All-Star, won 2 Reliever of the Month awards
- Diaz posted 2 months without allowing an earned run, 7 saves in July
- Mets using Diaz aggressively to compensate for short outings from starters

As of August 4th, 2025, the New York Mets' closer Edwin Diaz has been the most dominant reliever in baseball this season. Diaz was recently named an All-Star and has now won the National League Reliever of the Month award twice, taking home the honors in both May and July.
Diaz's dominance has been a key factor in the Mets' push for a postseason berth. The 31-year-old has posted two separate months this season without allowing a single earned run, including a July in which he was used 10 times, racking up 7 saves in 11 innings pitched while striking out 18 batters.
With the Mets' starting pitchers struggling to go deep into games, manager Carlos Mendoza has been leaning heavily on Diaz and the rest of the bullpen to secure victories. The additions of relievers Ryan Helsley and Tyler Rogers have built a sturdier bridge to Diaz, but the Mets' star closer could see even more creative usage if the opposing team's best hitters are due up in the seventh or eighth innings.

Diaz's dominant performance this season also has significant contract implications, as he has just two years and $40 million left on his current deal, which he can opt out of after the season. A strong finish could lead Diaz to test the open market, where he could likely secure a significant raise on his current salary.
