When South Portland pitcher and cleanup hitter Julie DiMatteo was hit by a pitch in the bottom of the first inning of last Thursday’s Western Maine Class A softball quarterfinal, her coach walked out of the dugout to make sure she was OK. From first base, she waved him off and said she was fine.

But she was angry.

“After I got hit, I think that set the tone for the rest of the game,” DiMatteo said. “It ticked me off a little bit. It was the best thing they could have done for us.”

DiMatteo pitched a complete game, no-hitter, striking out the first eight batters she faced and 11 overall as the No. 4 Red Riots defeated No. 5 Bonny Eagle 2-0 at Wainwright Field. It was the third straight year that South Portland has eliminated the Scots in the quarterfinals.

The Red Riots got all the offense they needed in the fifth inning. Through four innings, Bonny Eagle starter Maddie Kluna had allowed only one hit, a bloop single in the first by Stephanie Thibeault. But Kayla Ferrara started the bottom of the fifth off with a double to deep left field for South Portland.

Ferrara said she went up to the plate with one thing on her mind: hit the ball hard. She put all the recent advice and all the pressure of the playoffs on the back burner for a moment.

“I’ve been told so many things these past couple weeks and so much has been going through my mind,” she said. “I didn’t think. The best thing I could do was just not think, just focus on getting a hit.”

Even with the wind blowing in, her shot sailed over the head of the Bonny Eagle leftfielder.

“I hit it right off the sweet spot,” Ferrara said.

After a sacrifice bunt by pinch hitter Sara Eppich moved Ferrara to third, she came home on a fielder’s choice grounder to second by Amanda Linscott. The throw home was too late to catch Ferrara and Linscott was safe at first. A groundout moved Stephanie McDonough, pinch running for Linscott, to second. She scored on Kelsey Flaherty’s single to left to make it 2-0.

Bonny Eagle got its first baserunner in the top of the fifth when Kelly Bradbury reached on an error, but two grounders back to the mound and one to second got DiMatteo out of the inning.

LaShawna Jackson led off the seventh for the Scots with a well-hit ball to center that deflected off the glove of South Portland centerfielder Alexis Bogdanovich and was scored as a two-base error by the home scorekeeper. After a popout, Jackson advanced to third on a groundout. DiMatteo fielded a grounder back to the mound and tossed to first for the final out. Besides the 11 strikeouts, DiMatteo had a hand in six other putouts. She fielded five groundballs and caught a popup.

Kluna struck out three and allowed three hits. She pitched a five-hit shutout to lead her team to a 2-0 win when the teams met in the regular season in early May.

“Maddie Kluna is a great pitcher,” said South Portland coach Jim Hartman. “She’s a tough pitcher. In the three years that we’ve faced Kluna, it’s been 1-0 or 2-0. They’ve been great games. I can’t say enough about her and their coach.”

Bonny Eagle coach Jan Corliss said she was happy with her team’s effort against South Portland, a team with which the Scots are developing quite a history.

“We’re a thorn in each other’s side,” Corliss said. “We could play 10 times, we’d each win five. They came up to our place, we beat them 2-0. We come down here and lose 2-0. That’s the most runs we’ve lost by all year. We were 12-4 (entering the game). Those four games were 1-0, 2-1, 2-1 and 3-2. This game is the first game we’ve lost by two runs. It’s that kind of league this year with the top 5 teams. You’re not seeing a lot of high scores among the top 5 teams.”

The Scots finished at 12-5. South Portland lost in the semifinals to No. 1 Scarborough 1-0 on Saturday to wrap up its season at 14-4.
