Followers of the Portland Sea Dogs know all about pitcher Luis Diaz and his yearlong winless drought that finally ended last week in Binghamton.

On a sultry Sunday afternoon at Hadlock Field, Diaz pitched as well or better against those same Mets, allowing fewer hits and the same number of runs, but wound up on the losing side of a 3-0 decision before a sellout crowd announced as 7,368.

“He pitched well,” said Sea Dogs Manager Billy McMillon. “He kept us in the game, going six innings. It seems like it’s been a while since a starter went six innings.”

Actually, it was Diaz who had last gone that deep into a game, and Sunday was his third consecutive start of six innings.

He struck out five, walked four and yielded six hits (as opposed to 10 in last week’s victory). Aderlin Rodriguez homered off the video board in left-center to open the second inning and Binghamton tacked on two more in the third when Josh Rodriguez singled in a run and L.J. Mazzilli scampered home on a wild pitch.

That was it for offense in a game that started in 86-degree heat and resulted in Binghamton’s 11th straight victory at Hadlock, going back to the 2014 playoffs.

“There’s something about different ballparks around the league that your hitters feel comfortable hitting in, and Portland is one of them,” said Binghamton Manager Pedro Lopez. “We would love to keep on playing the way we are now. Portland’s known for having a good team and right now they’ve just hit a rough stretch. They’re still a good team. They’re going to come out (Monday) with everything they’ve got.”

The series concludes with a noon matinee Monday immediately preceding the All-Star break. Sunday’s loss guarantees the Sea Dogs (32-58) will sport the league’s worst record.

Oscar Tejeda doubled twice for the Sea Dogs, who left the bases loaded in the second and left two on in the third before going down quietly the rest of the game. Mets starter Seth Lugo (4-4), who won consecutive starts for the first time since 2013, scattered four hits over five innings before giving way to the first of four Binghamton relievers.

In a 6-1 loss Saturday, only one Sea Dogs baserunner advanced as far as third. On Sunday, only two made it that far.

“We just couldn’t scrape together good at-bats with runners in scoring position,” McMillon said. “Credit to their pitchers. Obviously, our hitters are trying, but we’ve got to get better at getting those runners in.”

Lugo has come a long way since being drafted in the 34th round in 2011 from a college (Centenary, in Louisiana).

Few scouts took notice of him.

“I didn’t throw very well in college, frankly,” Lugo said.

Back surgery wiped out his 2012 season, but Lugo has since climbed steadily through the Mets minor league system. He was a reliever in the Florida State League last summer but earned a starting job this spring.

Lopez, his manager, called Lugo a student of the game.

“He’s always paying attention,” Lopez said. “If you watch all the starters throwing their sides, he’s always out there, watching what (pitching coach Glenn Abbott) has to say. We do pitchers and catchers meetings before every game, and he’s the one guy who tries to execute that game plan to perfection.”

Lugo’s command wasn’t as sharp as normal Sunday, particularly with his off-speed stuff, but he refused to give in and throw something fat when behind in the count. That may have contributed to his pitch total of 94 through five innings, but it also frustrated Portland batters.

“He doesn’t miss over the plate much,” said Sea Dogs second baseman Carlos Asuaje. “He mixes his pitches and changes speeds.”

Lugo said he approaches every game as another tryout, another opportunity to prove he belongs.

“I’ve played with guys who were really good who didn’t make it this far, just because they didn’t work hard enough,” he said. “So I try not to make that mistake.”
