Felix continues to set benchmark

Reigning 200 metres champion Allyson Felix is still the athlete to beat after winning the USA national title in Oregon.

Felix, the Olympic silver medallist behind Jamaica's Veronica Campbell Brown in Beijing last August, ran a wind-assisted 22.02 seconds at Hayward Field in Eugene to win from Muna Lee (22.13) and Marshevet Hooker (22.36).

That meant no place for Lauryn Williams, the fastest American over 200m so far this year, although the former 100m world champion did make the US team for Berlin in August with a third place in the shorter sprint final on Saturday.

The USA Track & Field National Championships, which are doubling as World Championship team trials, concluded with a win in the men's 200m for former world title-holder Shawn Crawford, who ran a wind-aided 19.73 from Charles Clark (20.00) and Wallace Spearmon (20.03).

Lolo Jones suffered more disaster on the track as she failed to reached the final of the women's 100m hurdles.

Jones, ranked number one in the world in 2008, saw her Olympic dream ended at the ninth hurdle in the Beijing final last August and a mishap in her semi-final as she locked arms with Michelle Perry saw her lose rhythm and pull up before the finish line.

"I can only pick myself up and go to Europe and try to salvage my season," Jones said as fellow Olympians Dawn Harper (12.36) and Damu Cherry (12.58) finished either side of Virginia Powell (12.47) to secure passage to Berlin.

American record-holder Alan Webb failed to make the line in the men's 1,500m final having sustained a hamstring injury during the preliminary rounds.

The US 2008 Olympic flag bearer Lopez Lomong took the honours in the final, winning in 3:41.68 from 2009 US leader Leonel Manzano (3:41.82) and Dorian Ulrey (3:42.84).

There was one more notable withdrawal today as Olympic silver medallist and overnight leader Hyleas Fountain was forced to quit the heptathlon after five events with a neck injury sustained the previous night during the high jump.

In Fountain's absence, Diana Pickler took the title with 6,290 points, Sharon Day (6,177) and Bettie Wade (5,908) rounding out the podium positions.

Bershawn Jackson gained some revenge on Olympic champion Angelo Taylor by winning the 400m hurdles.

Taylor had led an American sweep of the medals in Beijing with Jackson in third behind reigning world champion Kerron Clement, who skipped the event this weekend having received a bye from the IAAF.

Jackson claimed the national title in 48.03 with Johnny Dutch second in 48.18 with Taylor third in 48.30.

Hazel Clark booked her place on the team for her fourth World Championships when she won her fifth national title at 800m in 2:00.79 from Geena Gall (2:01.01) and Phoebe Wright (2:01.12), while hometown favourite Nick Symmonds took the men's 800m in 1:45.86 from Khadeivis Robinson (1:45.97) and Ryan Brown (1:46.67).

Anna Willard qualified for Berlin for the second time this weekend, following on from her third place in the 1,500m with a runner-up spot in the 3,000m steeplechase.

Willard (9:35.01) lost out over the hurdles to her great rival Jenny Barringer, who clocked 9:29.38, with Bridget Franek third in 9:36.74.

US record-holder Teresa Vaill took the women's 20km walk with a time of 1:37:12.84, turning the tables on 2008 Olympic Trials champion Joanne Dow (1:39:59.32).

Men's high jump 2008 Olympic Trials champion Jesse Williams missed out on a ticket to Berlin on his return to Eugene as Tora Harris sprang a surprise as the only man to clear 2.31m (7ft 7ins).

Williams had to settle for fourth place on a countback of attempts to clear 2.28m (7-05.75), 2008 Olympian and 2009 world leader Andra Manson taking second, with Keith Moffat third.
