Johan Santana pitched two shutout innings to open today’s Grapefruit League game against the Cardinals at Digital Domain Park in Port St. Lucie, Fla. He threw 29 pitches, 17 of them strikes. He walked Shane Robinson and allowed a single to Mark Hamilton.

Santana’s command wasn’t there yet: He bounced a changeup, threw a couple sliders in the dirt and some fastballs way out of the strike zone. But the rest of it was: The cocky shimmy on the mound as he leaned in, the perfectly manicured Van Dyke, the athleticism he used to start a double play in the first.

The stadium gun even registered his fastball in the high 80s, topping out at 90 — a very positive sign for March 6. And Dan Warthen said that on the Mets’ gun, Santana hit 92 and sat at 90 for most of his outing. Seems crazy, I know.

Catcher Josh Thole said Santana was willing to throw all of his pitches in every situation. “It was fun,” he said. “There was no uncertainty.

“He said to me, ‘hey, be ready: I’ve got a second gear.”

Santana said this:

“This has been a great camp so far,” Terry Collins said. “But this has been the most positive day we’ve had.

“We take enough body blows as it is… enjoy it for once.”

It’s March 6, so it’s important not to get carried away. But then, it’s March 6 and Johan Santana is pitching in vaguely competitive baseball games, throwing fastballs at least in the high 80s, and looking and acting and sounding like Johan Santana.

So screw it: Get carried away. Go all Twitter on this and take it seven steps down the road. Let your imaginations run wild. It’s Johan Santana and he’s doing stuff and his arm still appears to be intact.

It’s hard to believe it’s for real, and that there won’t be speedbumps or roadblocks along the way for Santana. I get that. But as a fan, I want to roll the windows down and put the pedal to the floor until the next one arrives, since it has kind of been a while since I’ve enjoyed the thrill of the open road.

Really I just need this to last until tomorrow at midnight when the Doritos Locos Taco comes out. Is that too much to ask?
