RUMFORD — A high-and-mighty, early-afternoon sun probably cost Kyle Bourget a no-hitter, but Thursday otherwise was a perfect day for his Lisbon baseball team.

With a 10-0, five-inning shutout of Mountain Valley at Hosmer Field, Lisbon locked up No. 4 in the Class C West Heal Point standings.

The Greyhounds (13-3) know the significance, because it’s one spot ahead of where they finished the 2014 regular season. It allows them to avoid the dreaded preliminary round and assures a home quarterfinal next Thursday at Doughty Diamond.

“It’s a great win,” Bourget said. “That was our goal all season, to get top four, get the bye. And we wanted to play at home, so it’s good for us.”

Bourget weaved a one-hitter for his fifth victory of the season. The recent graduate didn’t allow a runner until Josh Mason’s rip to center field froze the drawn-in Greyhounds for a double with one out in the fourth.

Lisbon led only 1-0 at the time. After Bourget escaped with a pop-up to the mound and a grounder to shortstop, the Greyhounds erupted for nine runs on seven hits, two Mountain Valley errors and a pair of passed balls in the top of the fifth.

Darren Ward and Ryley Austin each had a two-run single off Falcons’ ace Tim Fitzgerald. Austin Fournier’s comebacker to the mound coaxed a throwing error that also plated two. Tyler Halls beat out two infield singles in the inning.

“That’s what we needed,” Lisbon coach Randy Ridley said. “We’re a free-swinging team. We’re not going to take a lot of pitches. It’s just not their style.”

Joe Philbrick and R.J. Sargent joined Halls with two hits for Lisbon, which will meet the winner of the Mountain Valley-Maranacook prelim.

Mountain Valley (7-9) qualified for the playoffs for the first time since 2009, when it reached the Class B regional semifinals.

“Bourget was just too much today,” Mountain Valley coach Steve LaPointe said. “He hit spots, and he was throwing hard. He actually threw well the first time, but today he was nasty. He was filthy.”

Lisbon’s go-to guy sported an ERA below 1.00 until struggling in his last two starts against Winthrop and Wiscasset.

This week’s rain gave Bourget six days’ rest to get ready for Mountain Valley, and now he’ll have another week off before Ridley gives him the ball in the playoffs.

“I felt more comfortable,” Bourget said. “I started to lose my mechanics a little in the other two games, but with almost a week break I got back in the flow of it.”

Bourget struck out six his first time through Mountain Valley’s order and eight overall.

He plunked pitch hitter J.T. Greene and walked Logan Wilhoite with two out in the fifth, giving the Falcons a chance to avoid the mercy rule, but shortstop Austin threw out Tucker Rowland by a half-step at first to end it.

“After the last two outings, where he struggled against Wiscasset, struggled against Winthrop, today was the day,” Ridley said. “We had a good bullpen session yesterday. I just wanted him to find his rhythm again, and it seems like he’s there.”

Lisbon needed two runs in the bottom of the seventh for a 2-1 win over Mountain Valley earlier in the season.

This was a similar pitchers’ duel for a while. Fitzgerald froze five Lisbon runners on base through the first two frames. Sargent’s single and walks by Bourget and Halls set up Fournier’s sacrifice fly for a run in the first.

“They hit the ball a lot better than they did the first time around,” LaPointe said. “They’re a good team, and they’re playing well right now going into the playoffs.”

Sargent’s leadoff single to left in the fifth was only Lisbon’s third hit of the game. Bourget followed with a line drive to the same spot, and Halls beat out a sacrifice bunt bid to load the bases.

Floodgates opened after Fournier’s at-bat, when the throw to the plate on the attempted fielder’s choice sailed to the backstop.

“We all started hitting. It’s nice to see us hitting, because we’re going to have to do that in the playoffs,” Bourget said. “They’re a good team. The first time we played them it was close. We just hit the ball today.”
