Nobody’s been hotter at the Aqueduct spring stand than jockey John Velazquez.

Since the 29-year-old reinsman returned to New York on March 17 from winter quarters at Gulfstream Park, he’s booted home 18 winners from 47 mounts – that’s a hefty winning clip of 38 percent – including a four-bagger yesterday to blow past Norberto Arroyo Jr. as the leading rider of the meet.

Velazquez, tied for third at the Gulfstream meet with a 52-for-287 slate, hadn’t won this many races on one card since last Dec. 17 at the Big A, when he scored with five.

“I love it here,” Velazquez said after winning aboard Prime Queen ($6.90 in the first), Corporate Phone ($6.90 in the fifth), Judge Roy ($14.40 in the sixth) and Affair in the Air ($18.20 in the seventh). “It’s my hometown, where my career started. I like Florida, the weather is nice, but I’m just down there following business.”

Velazquez, whose agent is Hall of Famer Angel Cordero Jr., attributes his current hot streak to “riding nice horses, and riding with confidence. That’s all it takes.”

Today will be the last chance in a while for bettors to cash in on Johnny V. at the Big A. Tomorrow he heads to Kentucky for opening day at Keeneland, where he plans to ride for the next couple of weeks with occasional trips back to New York.

“A lot of my customers are at Keeneland,” he said, “a lot of the horses I rode at Gulfstream.”

Those include trainer Todd Pletcher’s colt Invisible Ink, third in the Florida Derby, who is the jockey’s best hope of a top Kentucky Derby mount.

“We’ll see,” Velazquez said. “It depends on how he runs in the (April 14) Blue Grass.”
