Mike Stahr and Miles Irish, two former high school milers from New York state now roommates at Georgetown, ran within a step of each other for 450 meters before Stahr, a redshirt junior who ran for the New York Pioneers, won the men's 800 meters in 1:49.0 at the fourth annual Hoya Invitational track and field meet on Kehoe Field.

Eight meet records were set, including three by the George Mason women's team.

JoAnne Skinner, a sophomore at George Mason, broke her own meet record by more than nine feet in the hammer throw and teammate Terri Dendy set marks in the 100- (11.8) and 200-meter (23.9) dashes.

Charles Cherviyot, a Mount St. Mary's freshman from Kenya, established a meet record in the 1,500 meters, a race which he usually runs as a warm up.

"This is my workout for the 5,000 meter," said Cherviyot, who ran sixth in the longer distance at the Los Angleles Olympics, but did not run the 5,000 yesterday.

He might have turned a faster time if not for the stiff winds that whipped across Kehoe Field. "The gust of wind just killed him," said Mount St. Mary's Coach Jim Deegan. "He ran 43.9 over the last 300 meters."

Davison Lishebo, also of Mount St. Mary's, broke his own record in the 400 meters when he posted a 46.9.

Like the Mount St. Mary's men, the George Mason women were outstanding. "Our goal in this event is to stay sharp for some of the big meets," said George Mason women's Coach Norm Gordon. "Overall, we did a fairly good job."

The Patriots' Nena Gage jumped 39-3 1/2 to win the triple jump. But like many of the jumpers and distance runners who did not achieve national qualifying standards, her performance might have been enhanced by calmer winds and stiffer competition.

"It's tough to get NCAA qualifying marks on a day like today in a meet like this," Gordon said.

In the case of Skinner's record, more than the new distance will have to be retyped.

She set the meet's old mark last year when she was a freshman at Bucknell. Same event, same athlete, different school, new mark.

Skinner, a graduate of Yorktown High in Arlington who learned to throw the hammer last year as a freshman at Bucknell, transferred to George Mason and is eligible to compete because she competes in a nonrevenue sport and received permission from Bucknell.

She threw 142-9 yesterday, but might have thrown the ball and chain even further.

"My feet were great," she said. "But the arms were a little slow."

*Razorback Invitational: George Mason's Harold Morton won the 110-meter high hurdles in a meet-record 13.59 in Little Rock, Ark. He also finished second in the 400 intermediate hurdles in 50.89 and qualified for the June NCAA championships in both events. Ibrahim Okash of George Mason won the 800-meter run in 1:48.40.
