Edwin Díaz doesn’t typically need much help from anyone when he’s on his game — as he has been lately. 

In Wednesday’s 6-3 victory against the Angels at Citi Field, he played a crucial role. He got a key four-out save by striking out Luis Rengifo, who looked at the pitch with two on base and two outs, bringing the top of the eighth inning to a close.

All three called strikes were well outside the zone, which led Angels interim manager Ray Montgomery to get tossed after the inning. 

Díaz said he hadn’t seen the replays of the at-bat, but the closer wasn’t complaining. 

“I leave that decision to the umpire,” Díaz remarked. “If it’s called a strike, I’ll gladly accept it. Sometimes pitches in the strike zone are ruled differently, but today, perhaps I got lucky with those calls. I’m fine with that.”

And Díaz is also good with his recent workload. 

In Wednesday’s win, he got more than three outs for the third time in his past eight appearances after doing so just twice in his first 32 outings. 

Part of it is a product of an undermanned bullpen. Another is that with the season more than half over, Díaz said he’s prepared for the added outs. 

“When I’m feeling good, everything clicks,” Díaz said. “Today was one of those days. Whenever I’m needed and physically able to perform, I will step up. At the beginning of the season, pitching just one inning is typically preferable. However, now that we’ve moved into the second half and are contending for the playoffs, we have to win games, and I need to be prepared to secure more outs.”

Díaz ended up throwing 25 pitches, his second-highest total of the season, one of which was particularly scary. 

After escaping the eighth, an inning in which Díaz clipped Travis d’Arnaud as soon as he replaced Brooks Raley, Díaz drilled Chris Taylor square in the helmet with a 96 mph four-seam fastball with the first pitch of the ninth. 

Taylor stayed down for a moment, but stayed in the game — and Díaz quickly went back to work. 

His next pitch was a 97 mph four-seamer on the outside corner to Zach Neto, who struck out. Díaz retired the next two batters to finish the game. 

“I didn’t do it on purpose,’’ Díaz said of the Taylor pitch. “So I knew I could make the next pitch. I just gripped the ball harder. It was so dry today that I didn’t have a good grip on the ball. Then I was able to throw more strikes and stay on top of the ball.” 

Carlos Mendoza pointed to the Mets being off Thursday as a reason he felt comfortable pushing Díaz, who was pitching for the third time in four days — with Ryne Stanek closing out Tuesday’s win over the Angels. 

Overall, Díaz has tossed 15 ¹/₃ scoreless innings over his past 15 appearances, and has allowed just one earned run in his past 31 innings. 

And since a rocky start to the season, Díaz has been among the top handful of relievers in the sport, giving the Mets considerable security at the closer spot as they look to upgrade their bullpen prior to the July 31 trade deadline.
