BROOKFIELD -- This was no ordinary perfect game.

Granted, "ordinary" isn't an adjective that should precede "perfect game" under any circumstances, but the one thrown by Oxford's Ashley Guillette on Wednesday at Brookfield High School was perhaps even more impressive than most perfectos.

The Oxford ace cut through the Brookfield lineup, fanning the first 10 batters she faced en route to striking out 18 in a 4-0 victory.

"I try to block it out, but it's kind of hard," Guillette said. "We're pretty strong. Our hitting is pretty good and we're strong out there."

Only three Brookfield batters put the ball in play, and two of those were on bunts. Brookfield's Chelsea Coleman led off the bottom of the fourth with a sharp ground ball to the left side, but Oxford shortstop Megan Sastrum made a backhanded stab, got up and fired a strike to first for the out, keeping the perfect game intact.

"I was feeling pretty good. My team had my back," Guillette said. "Megan Sastrum got to that ball. That was a big save."

Despite Guillette's game-long dominance, a win was no lock for Oxford, largely because of the pitching performance of Brookfield's Samantha O'Brien, who also went the distance.

"(Guillette) was dominant today," Oxford coach Jim Husar said. "She's been doing well all year. She was on her game today, which she is most of the time. She was hitting her spots, and she's a hard worker. She's a great pitcher.

"We struggled with (O'Brien). She did a great job too. She went in, out, up, down. She threw a lot of balls in that we had trouble with."

Over her seven innings of work, O'Brien gave up four runs on six hits, four walks, three hit batters and five strikeouts.

"She pitched a great game," Brookfield coach Ventura said of O'Brien, who didn't allow a hit until the fourth inning. "It's good for her to get this one under her belt, and it's something she can build on for sure."

Oxford snapped the scoreless tie in the fifth inning on a one-out, RBI single off the bat of Kaley Kempf. Kempf's first of two hits plated Bobbie Stilson, who ran for Brittany Licursi after Licursi doubled to lead off the inning.

"We knew we had to hit all the way through, and it really helped when Brit started the inning off with a hit," Kempf said. "That was big for us. After my first two at-bats, I knew I had to do something up there."

The Wolverines gave themselves some breathing room by scoring three more in the sixth. Samantha Orner started the inning with a triple to right-center, Stilson notched a two-run base knock to right and Kempf collected her second RBI on a double over the center fielder's head.

Three outs from perfection and facing the top of the Brookfield lineup in the seventh, Guillette recorded her final three strikeouts (all swinging) to complete her gem.

"(Guillette) is a tough pitcher," Ventura said. "I thought we were in there for five innings with solid defense. They broke it open with a couple of clutch hits. I thought the girls played excellent defense from our standpoint."; Twitter: @jchik17
