BYU's Tiffany Lott, seeking her second straight heptathlon title, took the lead after the first four events with 3,652 points at the NCAA Outdoor Track and Field Championships Wednesday.

Lott is 46 points ahead of runnerup Tracye Lawyer of Stanford. Each had the best performances in two events, Lott in the 100 hurdles (13.28) and shot put (45-5) and Lawyer in the high jump (5-111/2) and 200 (24.22). Lott's teammate, Marsha Mark is eighth at 3,161, Shauna Rohbock is 12th at 3,116. Utah State's Jamie Hall is in 15th place with 3,040 points.The final three events - long jump, javelin and 800 - will be Thursday.

UCLA's Seilala Sua, meanwhile, is on track to accomplish what only one woman has done in the Championships - win four titles in the same event.

Sua, a sophomore, won her second consecutive discus title Wednesday, setting meet and stadium records with a heave of 210 feet, 8 inches.

"I'm excited about winning again," said Sua, also the 1997 Pan American Games junior champion in the discus and shot put. "I'm looking forward to the next two years."

If Sua wins again next year and in 2000, she would match the feat of Wisconsin's Suzy Favor, winner of the 1,500-meter title from 1987-90.

Arizona freshman Esko Mikkola also set meet and stadium records in winning the men's javelin at 268-7.

Sua's latest victory was by more than 18 feet as Aretha Hill of Washington, the collegiate leader this season at 215-3, finished a distant second at 192-5.

Sua's throw was short of her career best of 212-2, but surpassed the previous meet record of 209-10 by Leslie Deniz of Arizona State in 1983 and the University at Buffalo stadium record of 204-9 by Renatat Katewicz of Poland in the 1993 World University Games.

Other than her winning toss on her first attempt, Sua had only one other legal throw - 201-1. She fouled on her other four attempts.

Sua's victory was worth 10 points in the Bruins' bid to end LSU's 11-year reign as women's champion. Along with the fourth-place finish by Suzy Powell, the sixth by Nada Kawar and the seventh by Rachelle Noble, UCLA collected 20 points in the discus.

"It was important for the team to get a lot of points," said Powell, who ranked second this season at 213-5 but threw only 187-2 Wednesday. "We came close to what we expected to do except for me. We were counting on 23 points."

Mikkola's throw in the javelin shattered the meet record of 266-9 by Fresno State's Todd Reich in 1994 and the stadium mark of 261-3 by South Africa's Louis Fouche in the 1993 World University Games.

Mikkola, a former junior wrestling champion in the 180-pound class in his native Finland, also far surpassed his previous best of 250-7 in the Pac-10 Championships and became the No. 5 performer in collegiate history.

"When I saw that the throw was over 80 meters (262-5), I did a blackflip," Mikkola said. "That was my goal. I said if I broke 80 meters, I would do a flip."

Josh Johnson, a UCLA senior and the son of 1960 Olympic decathlon champion Rafer Johnson, finished fourth with a career-best 248-6.

Stanford sophomore Toby Stevenson, taking all his jumps while wearing a helmet, won the pole vault with a career-best 18-21/2.

Wednesday's other winners were Arizona's Amy Skieresz in the women's 10,000 meters in 33:04.12 and George Mason's Angie Brown in the women's long jump at 21-71/2.

BYU's Emily Nay was third in the 10,000 meters at 34:10.62.
