After a leadoff walk, Mercersburg No. 2 hitter Paige Richardson laid a bunt down the first-base line. Wenger's throw skipped past first baseman Taylor Lord, allowing the runner on first to reach third.
"They executed a bunt perfectly, and we just didn't stick it defensively," Agnes Irwin coach Laura Stott said. "We'd been great defensively all through the first couple innings, and this inning just got away from us."
The next batter, freshman pitcher Sydney Reath, ripped a line drive that bounced off the glove of third baseman Mia Lambo and into left field to score a run. Two batters later, designated player Val Langlois, the lone Mercersburg senior who graduated Saturday morning before a three-hour bus ride, hit a two-RBI single to the same spot.
All told, the usually lockdown Wenger gave up eight hits and three walks, with two hits and two walks coming in the fifth.
Asked how the game spun out of control so quickly, Wenger said, "I don't know. I couldn't even tell you."
"Things just happen," she added.
What was a stellar season for the Owls (14-3), who won their fifth straight Inter-Ac League title, ended because of Reath's dominance. The ace of the third-seeded Blue Storm (15-8) used a devastating riser-drop curve combination to strike out nine in a one-hit shutout.
Wenger's line-drive single up the middle to lead off the bottom of the fifth was the Owls' lone hit.
"We've never seen this team before, so some of us were a little timid up at the plate," Wenger said.
Despite the loss, Agnes Irwin players, coaches, and parents were all smiles after the game as players received silver medals and posed for photos. The team features just two seniors and a first-year coach.
"This gets us rolling into next season," Wenger said. "Get 'em next year - that's the only thing we can do."
Stott arrived at the school in the fall as a math teacher. When softball coach Lisa D'Orazio took a position at Friends' Central, Stott, a former Upper Darby catcher, took over as coach.
"It's been the greatest opportunity of my life," she said.
