Stanford's Jessica Tonn ran the fastest 5,000-meter time by a collegian this year to highlight a flurry of Cardinal personal records at the 20th Payton Jordan Cardinal Invitational on Saturday night.
Tonn, a fifth-year senior and five-time All-America, ran 15:18.85 to break her personal record by 15 seconds and move past three-time NCAA outdoor 5,000 champion Lauren Fleshman and into No. 2 on Stanford's all-time performers' list.
Tonn, who finished 13th in the loaded fast section that was won by Kenya's 2012 Olympic silver medalist Sally Kipyego in 14:57.44, is now No. 7 on the American collegiate comprehensive list.
Another highlight came from Claudia Saunders, who was second in the fast section of the women's 800 in 2:01.79, a personal record by nearly a second and a season best by five. It strengthens her position at No. 3 in school history.
Two meet records were broken -- in the men's 800 (Boris Berian, 1:45.30) and men's hammer (Great Britain's Nick Miller, 252-6).
At least two national records went down in the women's 10,000 -- Peru's Santa Ines Melchor Huiza (31:56.62) and Colombia's Carolina Tabares Guerrero (32:24.24). And numerous individuals reached qualifying standards for this summer's IAAF World Championships in Beijing, China.
Here are some facts about Saturday's action:
• Three world-leading marks.
• Seven U.S.-leading marks.
• Nine collegiate-leading marks.
• 57 exceeded World Championship standards.
