The Norton softball team had runners on first and second and two outs in the bottom of the ninth inning of its Division 2 South sectional quarterfinal against Dighton-Rehoboth when junior catcher came up with a clutch hit.
Grainger linedlined a single to left field, sending lead runner Destiny McGrath racing around third toward home plate.
The throw from left field was off the mark as McGrath scored the winning run and leapt into the waiting arms of ace pitcher Kelly Nelson to celebrate Norton’s dramatic 1-0 walkoff victory.
It was a sequence that produced the only of the game in a nine-inning pitcher’s duel.
Aside from relying on Nelson’s superb complete-game effort, which produced 20 strikeouts, Norton coach Wade Lizotte emphasized the importance of having a different offensive hero in every game.
“What I love about this team the most, and what I’ve always preached, is that this is a team,” Lizotte said. “If you look at all our past success, it’s always somebody new stepping up.
“This team, I have faith in every single one of them.”
Grainger’s hit was only the fourth of the game for Norton as Dighton-Rehoboth pitcher Emily Reid (11 strikeouts) and her defense shut down the Lancers lineup for much of the game.
“I knew I needed to get the ball in play,” Grainger said. “I wasn’t going to let the two strikes get me. I was right on her, it was just a matter of getting a pitch I knew I could get a hold of.”
In a scoreless game with so few chances for either team, the Falcons came closest to breaking the tie in the top of the seventh. After a leadoff double by Bailey Rassol, a sacrifice bunt got her to third base.
Nelson beared down and struck out the next hitter who attempted a squeeze bunt. Without hesitation, Grainger threw down to third to pick off Rassol for the third out.
After scoring just five runs in 16 postseason innings, Lizotte expressed little concern about his offense, given the tough pitching his team has faced.
“We had some really good at-bats up there,” said Lizotte. “We made [Reid] work. Dighton-Rehoboth is a top-four team as far as I’m concerned.”
