BINGHAMTON, N.Y. — The Portland Sea Dogs (59-33) were within one halfway through, but the Binghamton Mets (55- 37) roared back for nine runs over the final three innings and swept away the Sea Dogs with the 13-3 Eastern League baseball victory.

The loss marks the fourth in a row for Portland and the first time this year that the Sea Dogs have been swept in a fourgame series.

Luis Diaz made his first start against the Mets and was greeted by a four-run attack in the second inning. Travis Taijeron and Brandon Nimmo began the rally with a walk and single, respectively, before Xorge Carillo doubled to left and plated the pair to make it 2- 0. Diaz continued to struggle in the inning as Rylan Sandoval singled to put runners at the corners with one out. A throwing error on a pick-off play at first allowed one run to score, and Dilson Herrera hit a sacrifice fly to center.

Steven Matz was on the other side of the hill for the Mets and the young lefty came out dealing. He threw four perfect frames for Binghamton before Sean Coyle broke up the stretch of 12 in a row with a double to center. Coyle came around to score the Sea Dogs’ first run on a Keury De La Cruz single, which cut the deficit to 4-1.

Matz got out of the fifth without any further damage done, but gave up a pair of runs in the sixth. Heiker Meneses and Peter Hissey reached to begin the inning, and with one out Blake Swihart connected for a double to left that brought home both runners and pulled Portland to within one at 4-3.

That was as close as the Sea Dogs got, as Binghamton doubled its output with another four runs in the seventh off of Robby Scott. Back-to-back singles began the home half of the seventh and Brian Burgamy loaded the bases on an error.

The Sea Dogs return home and open up a five-game, fourday series against the New Hampshire Fisher Cats tonight at 7 p.m. at Hadlock Field. Jeremy Kehrt (0-0, 2.45) is scheduled to go for the Sea Dogs and will face off against a pitcher that has yet to be named for the Fisher Cats.
