Bumper prospects clash at Naas Only four line up for Saturday's Cavan Developments Home Builder Supporting Kill GAA Flat Race at Naas, but it throws up a fascinating clash between two horses prominent in the betting for the Champion Bumper at next month's Cheltenham Festival. Carter McKay looked a smart sort when winning on his first start for Willie Mullins at Leopardstown over Christmas and that form has been boosted since, with runner-up Bakmaj scoring at the same venue. He faces the impeccably-bred West Coast Time, who made a big impression when scoring on his debut for Joseph O'Brien at Cork last month. Patrick Mullins rode both horses to their debut victories and is unsure who will come out on top on Saturday. He said: "Carter McKay was good in Leopardstown and the form looks good with the second horse winning since. "However, I rode West Coast Time in Cork and he's a very good and very well-bred horse. "It's going to be an informative race and I'd be more hopeful than confident. "I think both of them are Cheltenham-standard horses and wouldn't be surprised if they're both in the thick of it in the Champion Bumper." Yaha Fizz bids for a hat-trick earlier on the card when lining up in the Jordan's Centra Supporting Kill GAA Rated Novice Hurdle. The Eamon Delany-trained gelding scored over course and distance last month before following up in style at Navan. The front-runner faces a stiffer task now after a stone hike for his latest victory. Another bidding for his third win in a row on the card is Heron Heights, who lines up in the Hospitality At Naas Handicap Chase. The progressive novice won a decent contest at Cheltenham when last seen in October but faces the prospect of softer conditions now on his return to handicap company.
