Diaz (5-2) took the loss Sunday against the Brewers, giving up one run on one hit in one-third of an inning.

EDGE Analysis

The Mets headed into the eighth inning with a 6-5 lead, but Ryan Helsley blew the save and needed to be replaced by Diaz to get the final out of the frame. The team's closer had his own struggles in the ninth however, as Isaac Collins took him deep to walk it off. It was the first earned run Diaz had been tagged with since April 21, but both his losses on the season have come in three August appearances, as he allowed the phantom runner to score in an extra-inning loss to the Giants on Aug. 1. Despite those recent setbacks, the 31-year-old right-hander has a stellar 1.60 ERA, 0.93 WHIP and 67:17 K:BB through 45 innings in 2025, converting 23 of 25 save chances.

The Mets added former Cardinals closer Ryan Helsley to their bullpen at the trade deadline to fill a setup role, but Diaz remains entrenched in the top job -- he hasn't been tagged for an earned run since June 2, delivering a 0.82 ERA and 26:9 K:BB over his last 18.1 innings along with an unsullied ERA.

Diaz loaded the bases with one out but was able to clean up the mess without snapping his scoreless streak, which is up to 17.1 innings. The closer's lone mistake in that span was allowing an inherited runner to score July 20 versus the Reds to take a blown save. He's plunked four batters over his last five appearances, but he's not at risk of losing closing duties at this time. For the season, Diaz has been elite with a 1.48 ERA, 0.89 WHIP and 64:16 K:BB while converting 23 of 25 save chances through 42.2 innings.

While his fastball velocity is down slightly to a career-low 97.0 MPH (compared to 97.5 MPH in 2024), the small dip hasn't impacted his dominance on the mound.
