Blizzard Of Oz lands Wexford feature The featured Michael Hickey Memorial Chase at Wexford ended up with a field of four after three defections and it developed into an intriguing duel between market principals Blizzard Of Oz (11/8) and Rocky's Diamond (1/1 fav).  The latter, with race fitness on his side after a winning chase debut at Galway last month, set out to make all in the hands of Michael Kenneally and Blizzard Of Oz stalked him throughout under Paul Townend. Between the final two fences, Kenneally was the first to go for his whip and the two horses jumped the last upsides before Townend's mount got the upper hand on the run-in to score by three-parts of a length. Just touched off in a novice handicap at the Punchestown festival when last seen in May, this was a first win over fences for the Arctic Cosmos seven-year-old who is trained for Simon Munir and Isaac Souede by Willie Mullins.  Daryl Jacob, representing the owners, said: "We're delighted with him. Obviously it's a sharp track and a nice, big galloping track would probably suit the horse an awful lot better.   "It was a good performance as the second horse is a very good horse. They went a nice gallop today.   "He is rated 147 and is a second-season novice, so we are looking forward to having a nice year with him. Today was an important day and we wanted to get it done with.   "I think he'll come on an awful lot for the experience. He is always a little bit ring-rusty on his first run of the season. He is entitled to go for better races after today.   "His jumping warmed up and got better, he just made the one mistake. On the whole we are very, very happy with that."  Additional reporting by Donal Murphy
