D'Antin disappointed by Barros' failure

After struggling for speed in qualifying and starting 17th, the Brazilian proved much faster in the race and reached seventh before retiring.

"This morning we set the bike up to have a great race, and as we showed from the start, I was making up positions and was looking good to have a good result with my Ducati," Barros said.

"It's such a pity that an electrical problem forced me to quit and ruined all the work we did this weekend.

"I'm very unhappy with what happened, and I'm sorry for the team. We'll do our best to put everything back the way it should be and get some points in Estoril."

Team boss Luis d'Antin was extremely disappointed for Barros.

"It has been a complicated weekend for us, but it actually could have finished well for Barros if not for the electrical failure," he said.

"It's sad because Barros was looking like he could have nailed sixth place or even better. I'm sorry for him, the technicians, and above all, the whole team."

In his first race back after suffering a severe hand injury at Laguna Seca, Alex Hofmann finished 11th on the second d'Antin bike. He was frustrated that he had lost 10th to Shinya Nakano in the closing stages as his painful hand began to hamper him.

"Though I feel like I had a great race, I'm not happy at all by the results," Hofmann said.

"This was one of the most physically difficult races I've ever had in my life, and even though I was able to pass Nakano in the final laps, my hand was giving out and under hard braking I lost the position back to Shinya.

"We're looking forward to a little rest before Estoril, where we're going to come out swinging and see what we can do."

D'Antin said Hofmann should be pleased with what he achieved given his condition.

"Hofmann clearly demonstrated his physical abilities, coming back from such a serious hand injury and showing that he was going to fight all the way until the chequered flag," he said.
