Sometimes, one unlucky inning can mean the difference between a win and loss. Or, in the case of the Class B North prelim baseball playoff game between No. 6 Gardiner and No. 11 Belfast on Tuesday, June 5, between moving on to the next round — or going home.

The upset-minded Lions drew first blood and held their ground — and the lead — deep into the fifth inning, but the hosts pushed across a pair in the frame, a development which proved just enough as the Tigers prowled to a 2-1 win.

With the victory, Gardiner (13-4) advances to the quarterfinals, where it will face No. 3 Mount Desert Island (11-5).

Belfast’s season wrapped at 9-8.

Belfast scored its lone run in the second inning, while Gardiner responded with two runs in the fifth.

Leading the Lions at the plate were Grey Dinsmore (2 singles, run) and Chris Kelley (single, RBI).

For the Tigers, Logan Porter (single, run), Kolton Brochu (single, stolen base), Alic Shorey (single) and Issac Gammon (single, run, stolen base) paced the offense.

Dinsmore for Belfast and Cole Lawrence for Gardiner went the distance on the mound for their squads.

Dinsmore allowed four hits, three walks and one hit batter, with two strikeouts for the Lions, while Lawrence allowed three hits and hit one batter, while he struck out three.

The Lions left four runners on base, while the Tigers stranded seven, including the bases loaded in the second.

“You know going in you’re not going to win with one run,” said Belfast coach George Ross, who coached his final game after a 37-year career guiding the Lions. “We’ve got to score more runs and that’s really what it comes down to. We had a couple opportunities and we didn’t get it done.”

“They’re a real good team,” said Dinsmore of the Tigers. “We played our hearts out and it’s just the difference of balls falling and balls not falling.”

Belfast got on the board in the second inning after Dinsmore connected on a single through the left side. Dinsmore then moved to second on a ground out by Dakota Payson, followed by a sacrifice bunt by Tyler Bartlett that shifted Dinsmore to third base.

Kelley then blooped an RBI-single to right-center field to put the Lions on the board.

From there, Dinsmore settled in on the mound and allowed one hit over the next three innings, including retiring the Tigers in order in the third and fourth.

But Gardiner got to Dinsmore in the fifth, which began when Gammon rapped a single and was moved to second on a ground out by Cam Bourassa. Porter then knotted the score on an RBI-single to plate Gammon and Porter motored into second base on the throw to the plate.

A Lawrence groundout moved Porter to third base, and he eventually came in on an infield single by Brochu, which ultimately proved the game-winner.

Belfast had one final chance in the sixth inning to manufacture the tying run when Hamlin reached after being hit by a pitch and Dinsmore followed with a two-out single through the right side.

But Payson hit a dribbler up the first-base line, and was met by the tag of the pitcher Lawrence, to end the top of the frame.

Ross said Dinsmore’s performance on the mound was “a real senior effort.”

“He’s a tough kid and he really wanted it,” said Ross of his stepson. “Held them to two runs? He did a terrific job.”

As far as Dinsmore’s thoughts after a gutty performance on the hill in his final game as a Lion?

“I’m just trying to cherish it,” he said. “Because I’m not playing college ball. This is it. It’s a rough senior year. That’s my third 2-1 loss [this season] with an unearned run. It’s really difficult. I love my team. I think we’re the best team in the state and on any given day, I’d pick my team over any other team we’ve seen.”
