Mann in hunt for summer double

Katies Tuitor bids for back-to-back successes in the totescoop6 Summer Hurdle at Market Rasen.Twelve months ago, Charlie Mann's six-year-old won off a mark of a 136 but will have to defy top-weight this weekend as his rating his risen to 150.Mann said: "We don't have that many options for a horse rated 150. We'll see where we go after that, he's got 11st 12lb in the Galway Hurdle so I wouldn't have thought he'd go there."He added: "Most of the field in that will have been prepared for that race for months so I don't think I'd be doing myself any favours carrying top weight in that. We'll know more after Saturday, the easy option is to go novice chasing."He's had an operation on his back since he last ran and he's a completely different horse this year, he's moving very well and I think he probably would jump a fence now."He's a much better horse now and he's much more supple. He could be anything."
