PORTLAND, Me. — More than anything, yesterday’s game with the Portland Sea Dog was about Manny Banuelos, the newest Yankees’ phenom, making his 2011 debut.

Despite tons of noise coming out of spring training calling for the 20-year-old left-hander to make the big club outright, Banuelos was sent back to Trenton.

After a delay to deal with a family matter back in Mexico, Banuelos got his first turn last night. He turned in four scoreless innings in an eventual 3-2 Thunder win in extra innings at Hadlock Field.

Overall, Trenton’s starter threw 64 pitches, allowed four hits, struck out one and walked one before being lifted for long reliever Craig Heyer.

After Heyer and Venditte held the Sea Dogs for four frames, an error from Corban Joseph followed by a single from Tim Federowicz off of closer Fernando Hernandez tied it in the ninth.

The Thunder answered in the tenth when Austin Krum led off with a walk against Sea Dogs reliever Santo Luis. Jose Pirela’s bunt pushed him to second before Austin Romine and Suttle drew back to back walks, with Brad Suttle’s coming intentionally.

Cody Johnson, who didn’t play in Sunday’s loss in New Hampshire, then lofted a sacrifice fly to deep left to score Krum from the third with the winning run.

Naoya Okamoto worked around a two-out hit to pick up to blank the Sea Dogs in the tenth and earn the save. Hernandez got the win.

Melky Mesa got the Thunder on the board in the second inning with his — and the team’s — first home run of the season, a solo shot.

Consecutive doubles from Austin Romine and Suttle gave Trenton its second tally.
