Alexa Efraimson Runs 4:03.39, New American Jr. Record At Prefontaine Classic



FULL RESULTS
Jenny Simpson won the highly anticipated women’s 1500 at the 2015 Prefontaine Classic in 4:00.98, but it was 18-year-old Alexa Efraimson who stole the headlines on Saturday afternoon as she finished seventh in 4:03.39, a new American junior record. Her time was more than a three and a half second PB, and takes six seconds off her previous 2015 World junior lead of 4:09.43 from Mt. SAC.
Simpson looked very sharp in her 2015 outdoor opener, running away in the last lap from a stacked field that included her American counterpart Shannon Rowbury. Kenyan Mercy Cherono was 2nd behind Simpson in 4:01.26, with the Netherlands’ Sifan Hassan 3rd in 4:01.65.

Jenny Simpson established herself as the early favorite for August's World Championships
Rowbury settled for fourth in 4:02.28. Americans finished in places 6-9, with Sarah Brown 6th (4:03.20), Efraimson 7th (4:03.39), Katie Mackey 8th (4:03.81), and Treniere Moser 9th in 4:04.26.
Souleiman Repeats In Bowerman Mile, Centro Impresses In 2nd

Ayanleh Souleiman held off Matthew Centrowitz to win his 2nd straight Bowerman Mile
Justin Gatlin Equals His 19.68 PB To Win 200 Easily

Justin Gatlin equaled his PB of 19.68 on Saturday at the 2015 Prefontaine Classic
Gatlin was well away from the field just 100 meters into the race. With Usain Bolt running nowhere near as fast as the American to start the 2015 season (Bolt just ran 20.13 in Ostrava on Tuesday), you have to wonder if Bolt is starting to get nervous about the World Championships in August…
19.68 for @justingatlin... @usainbolt right now... #PreClassic pic.twitter.com/Y5jnylON4i

Kirani James First Man Under 44 In 2015

Kirani James ran 43.95 in the men's 400 at the 2015 Prefontaine Classic
The time was a season’s best for the reigning World champion Merritt, who seems to finally be rounding into form with less than a month until the U.S. Championships. Even so, James is still a man against boys right now in the 400 meters.
Double Olympic Champ Kemboi Takes Down Birech, Jager Opens With 8:05

Kenyans Jairus Birech and Ezekiel Kemboi dueled to the final steeple on Saturday
American record holder Evan Jager ran the best steeple opener of his career, finishing in 8:05.28 to just miss his 8:04.71 PB that he set in September.
The Bowerman TC star was just off the pace of the top two Kenyans throughout the race, and looked crisp over the hurdles in his first steeple since the American record. With the 26-year-old opening at 8:05, the possibility of a sub-8:00 performance and a World Championship medal are certainly legitimate.
