LONDON (AP) - The gymnasts who excelled at last month’s national championships at Chaifetz Arena in St. Louis will be taking the floor at the London Olympics.

National champion John Orozco and Olympic trials winner Danell Leyva will compete in all six events when men’s team qualifications begin Saturday.

The U.S. lineup, announced Friday, means two-time Olympic medal winner and team captain Jon Horton will not be eligible for the all-round competition at the O2 Arena.

Horton finished third in the all-around at the 2010 world championships. He will compete on pommel horse, still rings, parallel bars and high bar.

Sam Mikulak, who injured his left ankle during trials last month, will do five events. He will sit out the rings while Jake Dalton will focus on rings, floor exercise and vault.

The top 24 all-around finishers qualify for the men’s all-around final Wednesday night.
