Diaz (1-1) was charged with the loss Thursday against the Cubs after allowing one run on two hits and a walk while striking out two over 1.1 innings.
After entering a tie game in the ninth inning, Diaz gave up a leadoff single to Kris Bryant before sending his next two batters down on strikes. Bryant was then caught stealing to finish off the inning. Diaz returned in the 10th frame with less success, hitting Matt Duffy with a pitch before a sacrifice bunt by David Bote put two runners in scoring position. Diaz proceeded to intentionally walk Eric Sogard, loading the bases with one out. A pinch-hit, walkoff single by Jason Heyward then strapped Diaz and the Mets with the loss. The 27-year-old reliever has two saves on the year to go with a 2.57 ERA and 1.29 WHIP across seven innings.
