It didn't take long for Sean Pruit to break an outdoor record.

In the Michigan men's track and field team's first outdoor meet of the season, the junior broke the school hammer-throw record in the first event of this weekend's Yellow Jacket Invitational at Georgia Tech University. The previous mark of 195 feet and 4 inches had been set by Patrik Johansson in 1999.

Pruit's throw of 196 feet and six inches also gave him a spot in the NCAA Mideast regional in May. Junior Vince Belitsos, another hammer-thrower, set a regional qualifying mark with a 191-foot 7-inch throw.

But overall, it was a quiet weekend for the Wolverines, whose chances to place in other events in the non-scoring meet were cut short by multiple rain delays. When lightning was spotted during the 800-meter run, the invitational was called to an end with seven events remaining on the schedule.

"It would have been great if we could have finished," Michigan coach Ron Warhurst said.

But Warhurst was satisfied with the individual performances of his athletes who were able to compete. Most of the invitational's participants were from southern schools, and had been practicing outdoors for some time. Warhurst said that it was the first time Michigan had competed in warm weather. Even on Thursday, the day before the invitational, most Wolverines wore gloves during practice.

"As the meets progress, they'll be getting all the rust off from being inside," Warhurst said.

But some runners have adapted quickly. In the track events, the sprinters and mid-distance runners gave the Wolverines top-10 finishes. Junior Andre Barnes and senior Stann Waithe finished fourth and seventh in the 400-meter dash, respectively.

Barnes and Waithe teamed up with freshman Nicholas McCampbell and junior Adam Harris to place fourth in the 4x100-meter relay. With a time of 40.73, that relay team ran faster than it did all last year.

Harris, coming off a fourth-place finish in the NCAA Indoor Championships two weeks ago, was the only athlete from Nationals who didn't rest this weekend.

In the distance events, Michigan nabbed two second place finishes - one from freshman Peter Christmas in the 3,000-meter steeplechase and another from junior Michael Luginbill in the 800-meter run.

Warhurst called the performance "a light test" for the Wolverines and a "tune up" for next weekend's dual meet against Big Ten rival Ohio State.

"Hopefully the weather won't be 30 and snowy," Warhurst said.
