Nick Woodbridge and Sam Weale have joined Jamie Cooke in the frame for Olympic selection by clinching top-10 finishes at the Modern Pentathlon World Cup final in Chengdu, China.
With only two places up for grabs, British selectors face the onerous task of having to omit one of the three men.
Woodbridge had a fine ride in the show-jumping leg of the event, taking down just one fence, to rise to fifth place in the standings, and he finished in the same position after the closing run/shoot. Weale climbed from 12th in the run/shoot to finish in seventh position.
Their lofty positions meant both men had achieved the London 2012 qualifying standard, which Cooke hit thanks to a fourth-place finish at the European Championships last year.
Cooke was off the pace in Chengdu, finishing 19th.
Russian gold medallist Ilia Frolov posted a total of 5,788 points, while Woodbridge had a score of 5,668, Weale 5,648 and Cooke 5,508.
The British squad for the home Olympics will be announced on June 8, after a selection panel meet.
Pentathlon GB performance director Jan Bartu is welcoming the competition for places.
Bartu said: "This is definitely evidence of a performance improvement we have achieved with the men's team over the last three or four years, which is great news for the programme.
"If we compare our performances today with other nations that are strong in the sport, it gives us a good feeling that we have a competitive edge two and a half months from the Games."
