Alejandro De Aza’s days with the Mets appear numbered.

The veteran outfielder isn’t hitting, and on Saturday, he received an earful from manager Terry Collins after his lack of hustle helped kill an inning.

With Wilmer Flores on first base in the 10th inning, De Aza popped up a bunt and slammed his bat in disgust — never bothering to run — as pitcher Jim Johnson settled under the pop up. Johnson alertly let the ball drop, starting a double play in which De Aza made a late effort to reach first base.

“Very surprising,” Collins said after the Mets beat the Braves 1-0 in 11 innings. “I’ve seen [De Aza] play, and the one thing he is known for is how hard he plays. But it goes to show you — everybody gets frustrated when they don’t do the job.”
