BINGHAMTON, N.Y.— Three errors led to three unearned runs Tuesday night as the Portland Sea Dogs lost to the Binghamton Mets 3-1 at NYSEG Stadium.

With the game tied at 1, a pair of errors in the fifth inning allowed Binghamton’s Jared King to reach second base, where he scored on T.J. Martinez’s single to center. Rivera later scored on a single by Josh Rodriguez.

“Tonight was a tough loss,” said Sea Dogs Manager Billy McMillon. “We just didn’t manage more consecutive good at-bats where we can drive in more runs.”

The four-game series is tied at a game apiece; the Dogs are 3-2 on their seven-game trip.

Portland (10-15) scored first for the fifth consecutive game on its current trip when Blake Tekotte scored Keury De La Cruz with a second-inning single.

Binghamton (15-10) responded immediately, tying the game in the bottom half of the inning on an RBI single from Gavin Cecchini.

The run was nearly avoided when a potential inning-ending double play ball was booted by shortstop Mike Miller.

“I made one of the errors myself,” said Portland starting pitcher Mike McCarthy on the Dogs’ defensive woes. “(Miller) made a great play right before that in the hole and those things happen.”

In the deciding fifth inning, King stung a ball up the middle that caught McCarthy on his leg with one out. After McCarthy retrieved the ball, he flipped a wild underhanded toss to first base that drew David Chester off the bag.

During the ensuing at-bat, a snap throw by catcher Luis Martinez short hopped Chester and ended up in foul territory down the right-field line, allowing King to scamper to second base. Then Cecchini followed with an RBI single.

“The two errors in the fifth are those that we can avoid in the future,” McMillon said. “If we made one of those plays, we probably avoid those runs.”

McCarthy did not allow an earned run in 42/3 innings. It was McCarthy’s second loss to Binghamton in as many tries, losing last Wednesday at Hadlock Field.

“McCarthy gave us a great start,” said McMillon. “He nearly got us into the fifth and after that, the bullpen was very good again.”

Binghamton starter Seth Lugo handled the Sea Dogs.

Lugo, a 25-year old right-hander, was pulled in the seventh inning. He fanned six, surrendering one earned run in 62/3 innings. The win also lowered his ERA to 1.37.

“He’s a professional,” said McMillon. “If he’s on and he does his job, he’s going to be tough for not only our lineup, but every lineup. He pitched well, competed and kept us off balance.”

Binghamton wrapped up the win with perfect outings from relievers Adam Kolarek and Paul Sewald.

Portland relievers retired all 10 batters. Dayan Diaz relieved McCarthy and pitched 21/3 innings with two strikeouts and Pat Light worked the eighth.

After Thursday’s game at Binghamton, the Sea Dogs return home to play New Britain.
