The U.S. Outdoor Track and Field Championships continued on Saturday with more national titles awarded. Here's the best of the best from the day.

Performer of the day: New Balance’s Emma Coburn was not fazed by the 86-degree California heat. The 2012 Olympic finalist pulled away from the rest of the field to win the 3,000-meter steeplechase in 9:19.72, breaking the U.S. Championship meet record and coming within two seconds of her personal best. Coburn also has the third fastest time in the world with her 9:17.84 set at the Prefontaine Classic.

Ashley Higginson (2nd, 9:27.59) and Aisha Praught (4th, 9:34.69) set personal bests in the race, cutting seven and five seconds, respectively, off their previous marks.

Race of the day: 2008 Olympic champion Dawn Harper-Nelson captured her third national title in the 100-meter hurdles, upsetting defending world champion Brianna Rollins in the final.

Rollins finished fifth in 12.81, but still owns the year's world-best time with her 12.53 from the Golden Gala in Rome on June 5.

Lolo Jones continued her return to track and field after competing at the Winter Olympics in Sochi with a third place finish in 12.65.

Comeback of the day: Olympic silver medalist Leo Manzano kicked down Patrick Casey of the Nike Oregon Track Club in the final 100 meters to claim the 1,500-meter national title in 3:38.63. Manzano is in his first season under contract with Hoka One One.

American record threatened: Erik Kynard attempted three high jumps at 2.41 meters. Charles Austin's American record of 2.40 meters has stood since 1991. Currently 5th in the World, Kynard has spoken only about his desire to attack the world record of 2.45 meters set by Javier Sotomayor in 1993.
