ERIC M. JUKELEVICS/Arizona Daily Wildcat Senior sprinter Mike Kenyon pulls away from an opponent last month at the Jim Click Shootout in Tucson. The Wildcats compete at home again this weekend in the Arizona vs. California Challenge.

The UA men's and women's track and field teams will play host to the first-ever California vs. Arizona Challenge this weekend.

Tomorrow's meet will feature Stanford and UCLA paired up as a team to compete against the combined squads of Arizona and Northern Arizona University in a dual-scoring meet.

Although the Wildcat women come into the meet ranked No. 14, according to the latest Trackwire 25 Poll, UCLA and Stanford are notorious for being Pac-10 powerhouses.

The UCLA women enter the meet ranked No. 3, while the Stanford women come in ranked No. 12.

On the men's side, Stanford is ranked No. 19, and UCLA comes in at No. 24.

With last weekend's meet primarily for the distance runners and pole-vaulters, this will be the first normal meet in two weeks.

However, the Wildcats are coming off of an impressive performance in last weekend's meet and look to carry that momentum into tomorrow's events.

Arizona managed to earn one automatic NCAA qualifying mark, three provisional NCAA qualifying marks and three Pac-10 qualifying marks.

UA sophomore pole vaulter Amy Linnen posted her best showing this season last weekend as she vaulted 14 feet, which is the highest in the nation in this year's outdoor season.

"Amy's talent is such that she'll be a 15-foot vaulter in the future," UA head coach Dave Murray said. "She'll have good competition this week with UCLA's Tracy O'Hara, who has already won an NCAA championship.

"There's no question that Amy can vault higher and, down the road, she has potential to be the best vaulter in the world."

UA assistant coach Fred Harvey, who will be replacing Murray after the season, knows this meet is important, as the outdoor season is quickly approaching its end.

"We want to go out and have a lot of fun, and we want to try to accumulate as many NCAA qualifying marks as we can," Harvey said.

"This is kind of a fun meet that the UCLA coach thought of last year," Murray said. "The bottom line is that we need qualifying times to get to the two big meets at the end of the season.

"Qualifying will be the key ingredient this weekend, and at this time of the year, we're running out of meets for our runners to run fast, our throwers to throw far, and our jumpers to jump high."

Field events will begin at 11 a.m., and running events will start at noon. All events will be held at Drachman Stadium.
