Injured Yankees pitcher Michael Pineda was busted for DUI in Tampa, Fla., on a busy road early this morning after a cop spotted his speeding, “weaving” Nissan SUV driving without its headlights on, authorities said.

The burly Pineda, 23, “had a fixed gaze and his eyes were bloodshot, watery and glassy,” a Tampa police officer wrote after pulling the 23-year-old hurler over at 2:35 a.m. on North Dale Mabry Highway.

“I could smell a distinct odor of an alcoholic beverage coming from his breath, and his speech was slurred,” the cop wrote about Pineda, who was an All-Star in his rookie season last year with the Seattle Mariners.

The Dominican Republic native’s blood-alcohol level was found to be .128 and .125 in two separate readings, according to police records.

He was charged with driving under the influence of alcohol, and released on a $500 bond from jail shortly before noon today.

Yankees General Manager Brian Cashman told The Post “no comment” when asked about Pineda’s arrest.

Pineda was traded to the Yankees earlier this year in a multi-pitcher deal with the Mariners, who received hot Bronx Bombers prospect Jesus Montero in return.

He showed up to spring training significantly overweight, and soon afterward was injured.

He currently is out for the season after undergoing shoulder surgery, and has been living in Tampa undergoing rehab from that surgery.
