Yankees catcher Russell Martin said he was “mystified” by the behavior of home-plate umpire Laz Diaz during Wednesday’s 6-5 victory over the Angels, saying that Diaz would not permit him to throw new baseballs to the mound during the game.

Martin said that he likes to throw the ball to keep his arm loose following foul balls but was told by Diaz — a full-time Major League umpire since 1999 — that it would not be allowed because it is, as Martin said, “a privilege that I have to earn.”

“At the end of the game, after I got hit in the neck [by a foul tip], I was like, ‘Can I throw the ball back now?’” Martin said. “He was like, still, ‘No.’ I was like, ‘You’re such a [jerk].’ Like, for real, unbelievable.”
