Saturday tips: Dave Nevison shares his four best bets

Callum Pritchard has ridden for 11 different trainers in his first 18 rides as a conditional, suggesting either he has a brilliant agent or trainers know how good he is and want a piece of the action while he has a valuable claim. 

Either way, I was impressed when I saw him ride a big outsider into fifth place over fences at Cheltenham last weekend and am very happy to be with him on a much more strongly fancied runner here. 

Hell Hound has only had four runs but has already won a bumper and a hurdle. He looks a very promising type. 

He reappeared after a three-month summer break at Fontwell over a trip that is possibly already too sharp for him. He stayed on nicely to finish third. 

The handicapper has not been harsh with his opening mark of 105 and with Pritchard’s claim against fellow conditionals he could be very well weighted, especially now back up in trip.

Wal Bucks is described as a chasing type by Timeform and is certainly bred for fences, so it is no surprise he was switched to the bigger obstacles as a five-year-old after just one run in a bumper and three efforts over hurdles. 

He was placed in a maiden point to point and his chasing debut at Perth was obviously expected to bring about improvement as he was sent off favourite, but he was not convincing early in the race and was given a gentle introduction after that. 

He  finished full of running, so if he has been well schooled over the summer I expect him to do a lot better in this very modest affair. He has been dropped to a mark of 102 but still gives weight all round here. I expect him to be too strong for this level.

Mister Chewy progressed from winning a novices’ handicap chase off a mark of 121 this time last year to coming second - beaten a head - in the Grade One Maghull Novices chase at Aintree, picking up the Wayward Lad Novices’ Chase at Kempton  along the way. 

I very much doubt he will run in too many handicaps this season but this one might well be a good starting point for the season. He came back with a win after a six-month break last season and attempts to do the same here. With the Twiston- Davies team in such good form, he can defy top weight. 

I watched Toby McCain-Mitchell very closely when he was riding The Newest One (my tip!) around Cheltenham last weekend and was seriously impressed, and Nigel Twiston-Davies booking him to ride against professionals in this Saturday handicap takes the eye. 

Topofthecotswolds returned after a year off in September and looks like he has been running himself into peak fitness judged on his two runs. 

I thought it was significant that he seemed to blow up and then stay on at the end of the race at Ludlow last time, suggesting he will be suited by the punishing straight at Wetherby. 

His mark has dropped 5lb since the start of this season and he is 11lb lower than his latest winning mark. Three miles seems to be perfect for him.
