BLOOMINGTON — The Michigan offense was in full swing yesterday against Indiana. But with junior Jennie Ritter on the mound, it didn’t matter.

In the doubleheader, Ritter pitched eight and one-third no-hit innings to help the Wolverines finish off a perfect weekend. Against the Hoosiers, Ritter had her own perfect moment. She tossed a five-inning perfect game in Michigan’s 9-0 win in yesterday’s first matchup. In the second game, she came in for three and one-third innings of relief to seal a 10-2 victory. Ritter finished the weekend with a 4-0 record, starting two games and relieving sophomore Lorilyn Wilson in the other two.

“It’s actually concerning (that Ritter got all four wins),” Michigan coach Carol Hutchins said. “I need two pitchers; we are not a one pitcher team. But it’s important when one pitcher is off, the other one is on. I thought (Ritter) picked up a big load and carried it.”

Michigan (11-1 Big Ten, 44-3 overall) jumped out to a 2-0 lead in the first game thanks to a two-run homer from first baseman Samantha Findlay. That was all the run support Ritter would need. She took control of the game for five dominating innings and notched the first perfect game of her career.

“It’s funny because there’s kind of like an unwritten rule that nobody’s allowed to even think about (the perfect game),” Ritter said. “I wasn’t thinking (about) it. I was just thinking about throwing good pitches.”

Indiana — which is hitting just .221 as a team this season — looked helpless against an overpowering Ritter, who improved her record to 21-0. Although the two first batters managed to get the bat on the ball to groundout, Ritter struck out the next four. Not a single Hoosier (2-8, 12-31) managed to hit a ball past the infield the entire game.

In total, Ritter struck out nine of 15 batters she faced, including five of the last six to end the game in a five-inning mercy rule win with a score of 9-0.

“I definitely think it helps out (to strike out batters) because more strikeouts means less chances for errors in the field,” Ritter said.

Despite their strong play in the opening game, the Wolverines’ unblemished weekend record looked to be in jeopardy during the top of the third inning of the second game. Wilson struck out the first six batters to start the game, but she soon found herself in trouble on the mound.

After walking sophomore Heather Haas and hitting second baseman Ashley Griffths, Wilson faced runners on first and second with just one out. Indiana catcher Tory Yamaguchi smashed a line drive down the first-base line that ricocheted off Findlay’s glove and went into rightfield. Centerfielder Kim Richards scored on the play to give the Hoosiers their first run of the weekend. The hit left runners on second and third base.

It looked like things were going to settle down when designated player Lauren Hines hit a hard grounder back to Wilson. The sophomore calmly fielded it and tossed it to Marx to catch Griffths in a run down. But Yamaguchi advanced to third on the play and came home when Wilson threw a wild pitch, leaving Indiana down just 3-2.

But the Wolverines did not need to worry. Ritter entered the game and continued to cut down Indiana. Ritter forced a weak groundball from designated player Anna Olson that she fielded in the pitcher’s circle and tossed over to Findlay at first.

“The coaches talked to me before the game and told me I needed to step up my game,” Ritter said. “I come to play so that, when I get in a situation like that, I can do well. It was tough, but I got to show up.”

Michigan soon made back what it had lost. In the bottom of the inning, senior Jessica Merchant and Findlay smashed back-to-back solo home runs, giving the Wolverines a 5-2 lead.

“It definitely shuts a team down that was trying to big up their confidence, so I think we just shoved it right back down,” Findlay said.

And the Wolverines fell back on Ritter to finish off the Hoosiers. Ritter was nearly flawless in her next three innings of work. She struck out eight of the remaining nine batters she faced, and, had it not been for a full-count walk in the top of the fifth, she would have finished the day with eight and one-third perfect innings.

Ritter’s solid pitching did not mean the Wolverines got lazy at the plate. Michigan added five more runs, including a two-run homer from Findlay in the bottom of the sixth to seal a 10-2 mercy-rule victory. Findlay ended the game 3-for-3, with three home runs and five RBI.
