Mark Sanchez is hitting midseason form in May.

The Jets quarterback who has brought you 52 turnovers in the last two years — the most in the NFL by any player — threw three interceptions yesterday in the first practice of the spring the media was permitted to watch.

The turnovers from the fifth-year quarterback already have head coach Rex Ryan agitated.

“It is absolutely [disappointing],” Ryan said. “It’s a good thing the defense made some plays ... I’d rather him not turn the ball over once, obviously.”

Sanchez is beginning a battle with rookie Geno Smith for the starting job. Neither quarterback performed well yesterday as the defense confused both of them with Ryan saying he threw the “kitchen sink” at them.

In 11-on-11 drills, Sanchez went 6-for-11 with the three picks and one sack. Smith went 3-for-10 with an interception and a sack.

Mistakes from Smith are expected. With Sanchez, it feels like Groundhog Day. The only difference was Ryan’s reaction. In the past, Ryan has been protective of Sanchez. He seems as if he has had enough.

“That’s going to be the pressure that we’re putting on him that no, no, no, this is unacceptable,” Ryan said. “You did a lot of great things and it’s not that you try to cover up that you had some bad plays ... no, no, no, you flat tell him we can’t have these. He knows.”

Sanchez’s worst moment of the day came when 350-pound defensive tackle Damon “Snacks” Harrison intercepted him in the backfield.

“A couple of those throws I want back,” Sanchez said. “Of all people, freakin’ Snacks, that’s like your worst nightmare. But I was just trying to make a play, that’s one of those things where I should pull the ball down and run or something. I’m shaking the rust off a little bit, getting back into the swing of things, especially with a lot of young guys.”
