PONTHIR’S James Ball is a double world champion after winning two golds at the Para-cycling Track World Championships in Los Angeles.

The visually-impaired 25-year-old and pilot Matt Rotherham set the fastest time when they were the penultimate pair to ride in the 1km time trial on Saturday.

They watched on as Commonwealth Games champions Neil Fachie and Craig Maclean, who was Ball’s pilot at the Rio Paralympics last year, failed to better their time of 1:00.727.

Ball and Rotherham then repeated the trick on Sunday in the tandem sprint, posting an impressive time of 10.047 seconds in qualifying to go straight through to the semi-finals.

They beat their Russian rivals 2-0 to set up an all-British final with Fachie and Maclean, who won the first heat.

Ball and Rotherham levelled it up before going early in the decider and holding onto their lead for a second gold.

The pair have only been together since January and the Welsh rider was thrilled with their stunning showing in LA.

"I still can't put it into words. That wasn't in the plans to come out here and win two golds," said Ball, who used to be a sprinter on the athletics track.

"We just wanted to come out here and see how we'd get on as a pairing but we knew we were going quick so I'm really happy it's all come together."
