United States boxer Rau'shee Warren hopes it will be a case of third time lucky for him at London 2012, with his sights firmly set on rounding off his amateur career with an Olympic medal before entering the professional ranks.
The 25-year-old flyweight from Ohio is set to make history this summer by becoming the first American fighter to compete at three Games.
He has contemplated going pro in the past, but says the sense of unfinished business he has been left with after the early exits he suffered at both Beijing 2008 and Athens 2004 have convinced him to carry on for another cycle.
Now, with London only a few days away, Warren is fully geared up for what he is determined will be a successful campaign that will send him into the pro scene as an Olympic medallist.
"I'm happy that I have achieved this, being the first American boxer to go to a third Olympics - that is making history, but now I have to put a medal on top of it," he said.
"After London, I'm looking forward to going professional.
"I feel I have made my mark by being the first American to go to the Olympics three times, but I am giving up the amateurs.
"After the 2008 Olympics I wanted to go professional, but I decided to stick around and go back for the third.
"I had lost and I didn't want to go professional having lost out twice at an Olympics - I want to do it as a medallist."
Warren - who won an amateur world title in 2007 - feels the Olympic experience he has gained over the years will count for a lot in London.
"I feel like if I complete everything in training, then there should be no doubts in the ring once I compete," Warren said.
"I'm taking advantage of the first two times for this third time.
"I will take my experience and the mental side and put everything into one, and when it is time for competition, that has got to show."
Warren was speaking in Bolton, where the US Olympic boxing team have been spending time as part of their preparations for London working with Amir Khan, Great Britain's Athens 2004 silver medallist.
Khan has just returned from the States following his bruising defeat to Danny Garcia in their light-welterweight world title unification bout in Las Vegas last weekend.
It was his second successive loss - the previous one being last year's controversial points defeat in Washington to Lamont Peterson, who later failed a drugs test - and his third as a pro, and there have been questions raised as to where, if at all, Khan's career should go from here.
The man himself insists he has plenty more to offer, though, while Warren says Khan is still seen as a big name in America.
"I can't speak for everyone in America, but in our team, we look at it (Khan's defeat to Garcia, in which he was floored three times en route to a fourth-round stoppage) as anything can happen in a fight," Warren said.
"You can have everything on point and then one shot can just change the whole fight.
"He is still a big name out there - this is boxing, and you just get stuff like that happen in boxing.
"Every champion fails sometimes and they have to crawl back up."Tags: Amateur Boxing
