O'Brien worried about Rip fitness Aidan O'Brien today revealed that Rip Van Winkle should improve for the run when he lines up in the Queen Anne Stakes at Royal Ascot on Tuesday. Speaking today at Cork the Ballydoyle handler said the dual Group One winner was working well but may just need the run. "He's working really well but I'm a little bit worried about his fitness as he has not had a run," said O'Brien. "The way our other horses came forward after a run would suggest he should improve."
