Nike's slogan is simple: "Just Do It."

According to Michigan men's tennis sophomore Jason Jung, that’s exactly the attitude the Wolverines need to follow if they expect to improve their play — even if their uniforms now have an adidas logo.

After beginning the year 5-0, No. 28 Michigan has lost seven of its last eight matches, with its latest defeat coming last night at No. 25 Notre Dame, 5-2.

“We definitely feel like we can hang with the teams we’ve been facing,” Michigan coach Bruce Berque said. “But right now, some guys are not playing well, and many of them are struggling with their confidence.”

The Wolverines (6-7) began play by sweeping the three doubles matches for the second straight meet.

Jung and senior George Navas secured the last doubles win by upsetting Notre Dame’s 21st-ranked pair 8-4.

Winning the doubles point was a struggle for Michigan earlier this season. As a result, Berque recently switched his doubles pairings and kept the same partners for the last two matches.

“Doubles was something we have worked on in practice a lot lately,” Berque said. “We are getting better there, and the success has given the guys an emotional boost as well.”

The Wolverines hoped that momentum would carry over to singles play.

Michigan had no such luck against the Fighting Irish (8-7).

After Michigan dropped its first three matches, redshirt freshman Drew Daniel defeated his No. 6 singles opponent, 6-2, 7-6.

But just like during the Wolverines' match against Washington on Feb. 27, they would struggle during singles play against Notre Dame (8-7), losing five of the six matches.

“We worked on doubles, and we were able to get some confidence from winning,” senior Andrew Mazlin said. “Hopefully we can practice with singles, get some confidence, and regain that swagger.”

Last year's squad seemed to have that swagger. At this point last season, the Wolverines were riding high at 7-2 and ranked No. 19 in the country.

Big Ten play begins in less than three weeks, and Michigan needs a boost. That starts with singles play.

“When playing by yourself in singles, you have to be very tough mentally,” Berque said. “Right now, some guys are not prepared, and the coaching staff definitely has to do a better job of getting the guys mentally focused."

But talk can be cheap.

“Everyone needs to stop thinking,” Jung said. “It’s a matter of just doing it.”
