I knew if I was in contention at 300m the race was mine Tim Benjamin Day two as it happened

Daniel Caines led a highly competitive race coming off the bend but Wales' Benjamin pushed him into second to cross the line in 45.58 seconds.

Sean Baldock took third while American-born Malachi Davis settled for fifth.

"The conditions aren't great here so I think I can go sub-45 with a bit more preparation," said Benjamin.

Davis, who came into the competition just three days after gaining a British passport, will now have to pin his hopes on securing a spot on the relay team.

"I think Malachi is great," said Benjamin. "We need more guys like him to strengthen the team."

There was a surprise in the women's event as 20-year-old Christine Ohurougu pipped favourite Lee McConnell to the title.

Ohurougu was shocked to record a lifetime best of 50.98 seconds in gloomy conditions in Manchester.

"I didn't anticipate winning because the field is so strong," said the Croydon athlete.

"Lee was so close and I thought I'll stick on her shoulder and maybe I can pick her up."

GB OIympic team so far

Darren Campbell pulled out of the 200m with hamstring and rib injuries, but is expected to make a full recovery ahead of the Athens Olympics.

In his absence Chris Lambert took the AAAs title ahead of Christian Malcolm in a time of 20.94secs.

"I don't know what was up with the time but I'm just glad I got my focus together and get it right," he said.

Malcolm came home in 21.09secs with Dwayne Grant, who pulled a hamstring at the line, in third.

Denise Lewis was another big name to withdraw from the action after injuring her foot in the long jump.

"I did three jumps but decided it was best to pull out as I'm concerned about the foot," the heptathlete said.

Jade Johnson won the event with a season's best first leap of 7.62m that booked her seat on the plane to Athens.

"I take time to get into the season and usually the second half of the season is when I find form - I'm just happy to qualify," she said.

Kelly Holmes was in dominant form as she picked up her seventh AAAs 800m title and easily surpassed the Olympic qualifying mark.

The 32-year-old moved to the front of the pack at the bell to win in one minute, 59.39 seconds ahead of Jo Fenn and Scotland's Susan Scott.

But despite easily justifying her selection in the two-lap race, Holmes intends to focus on the 1500m in Athens.

"Because the 1500m is second in Greece it makes my decision harder but I still have an option," said Holmes.

"I just needed to use this race for speed work and get a good solid weekend."

Hayley Tullett continued her comeback from injury with another fine performance in the 1500m, winning in a time of 4.07.24.

"I just need to focus after the injury. I'm staying positive and want to go to Athens in good shape," she said.

Pre-race favourites Tony Whiteman and James Thie failed to show their class in the men's event.

The pair were overhauled in the final 200m of a slow race won by Chris Mulvaney, with Andrew Baddeley second.

With Phillips Idowu out of the triple jump, Nathan Douglas stole the headlines with a jump of 16.95m that seals his place in the Olympics.

"It's a dream come true," the 21-year-old said after hitting the qualifying mark on the button.

"I was hoping for a ticket to Athens, it was a possibility but I didn't really think it would happen.

"I can't believe I'm going, but with me and Phillips out there the future looks bright," he added.

Steve Backley won the javelin title with a mark of 80.25m but was left frustrated by his efforts.

"I'm in better shape than that," he said. "It's not a good reflection of my form but I have time to sort it out."

Chris Rawlinson cruised to his expected easy victory in the 400m hurdles having already qualified for the Olympics.

"The trials mean a lot to me but there wasn't a lot I could get out of it. I've done everything I need to do and now I just need to stay fit," he said.
