When Mike Olt hit his ninth-inning sacrifice fly to left field, tying the game, it looked like these Portland Sea Dogs were just not ready to lose.

But they did, finally.

The Binghamton Rumble Ponies put together four singles and one run in the 11th inning to take a 4-3 decision over the Sea Dogs Wednesday afternoon at Hadlock Field.

Portland lost for the first time this year, finishing its season-opening home stand at 5-1, while Binghamton is 3-3.

“You always want to play well at home,” Sea Dogs Manager Carlos Febles said. “Everything is clicking. Things are going our way. That’s a very good sign.”

Jamie Callahan (1-1), who pitched a 1-2-3 10th, gave up the run in the 11th. With one out, he allowed a Tomas Nido single and then a Luis Guillorme single capping an 11-pitch at-bat.

“I think that wore him out,” Febles said.

Jio Mier singled to load the bases. Callahan struck out Champ Stuart for the second out. Patrick Biondi came up and worked a full count, meaning the runners were going on the pitch.

“The 3-2 pitch was a slider and I just tried to put it in play,” Biondi said. “Luckily, it went our way.”

Biondi hit a hard grounder past the mound that shortstop Heiker Meneses made a diving stop on. But with the runners going, Meneses had no play at second. He fired to first, but Biondi beat the throw, and a run scored.

Ben Griset (1-0) pitched a second scoreless inning in the bottom of the 11th.

Sea Dogs starter Teddy Stankiewicz put in a solid day with seven innings of work. He gave up eight hits and three runs (two earned), walking none and striking out five.

Stankiewicz now has two no-decisions, with a 2.77 ERA and an Eastern League-leading 13 innings.

“He kept us in the game and worked it around pretty well,” Febles said.

A throwing error contributed to an unearned run in the first for Binghamton.

The Sea Dogs came back with two runs in the second on singles by Rafael Devers and Jose Rosario and two throwing errors.

Binghamton tied it in the fourth. Right fielder Joseph Monge misplayed Kevin Kaczmarski’s line drive into a single, allowing it to bounce in front of him.

“He just had a bad read on it,” Febles said.

A wild pitch and groundout advanced Kaczmarski to third. He scored on Nido’s sacrifice fly.

In the fifth, Mier’s RBI double put Binghamton up 3-2.

Binghamton starter Tyler Pill (0.00 ERA) and two relievers then retired 20 out of 21 batters, heading into the ninth.

In the ninth, Meneses led off with a single. Cole Sturgeon singled him to third, and Olt scored Meneses with a sacrifice fly to left. Sturgeon reached second but was stranded.

In the 10th, Portland had a runner on second with two outs, but he was stranded.

The Sea Dogs begin a seven-game trip Friday in Trenton. They take Easter off and play a series in Binghamton. The team returns to Portland April 21.

NOTES: The announced paid attendance was 2,431, although the actual crowd was about one-tenth of that for the weekday matinee. … Binghamton added a familiar face to its roster, although first baseman Cody Decker did not play Wednesday. Decker, 30, played for the Sea Dogs last year and then signed with the Brewers in the offseason. The Brewers released him near the end of spring training and he signed with the Mets. … Devers went 1 for 5 but is still batting .333.
