Cameron Beaubier feels his crash on his World Superbike debut put him in an even greater disadvantage and despite grabbing a top ten on his maiden finish looks at the weekend as a missed opportunity.

The reigning MotoAmerica Superbike champion became a late stand-in rider at Pata Yamaha for the injured Sylvain Guintoli at Donington Park, but soon found himself as the sole factory Yamaha contender after Alex Lowes was cruelly forced to withdraw due to the pain in his broken collarbone.

After impressing in his first qualifying in World Superbikes by grabbing an automatic berth into Superpole two, Beaubier suffered heartbreak in race one when he crashed out at the final turn on the opening lap.

Looking to make amends and repay the faith given to him by team boss Paul Denning, Beaubier ensured he saw the chequered flag in race two in 10th place but feels he could have scaled greater heights had it not been for his off in the opener.

"I struggled for the opening third of the race just because, honestly, crashing on the opening lap yesterday hurt me more than I originally realised just with the lack of track time and losing all that experience," Beaubier said. "The second half of the race I felt a lot better on the bike, two guys came past me and I thought they were going to leave me but slowly I started to chip away and claw my way back to them, which felt good.

"I feel that if Sunday was Saturday and we could start on a new day after the race we've had we would have been able to put myself in a much better position.

"I'm not really happy with tenth, obviously I want to be a bit higher up than that, but I'm happy with how I felt towards the end of the race. I wanted to try to pass one of them on the last lap but I ran out time."

Despite his frustrations, Beaubier left his debut World Superbike round in an upbeat frame of mind and is aiming for a return in the future after he concludes his 2016 campaign in MotoAmerica.

"Most importantly I just want to thank Pata Yamaha for giving me this opportunity and for Yamaha US for letting me come to do this," he said. "It was a really fun weekend, I learnt a lot and I hope to do it again someday."
