ALAN Munro showed all the talent which has made him one of Europe's hottest young riders when banging home a 72-1 double at Happy Valley last night. The English and Irish Derby-winning jockey scored on Gary Ng Ting-keung's 6-1 chance Successful Way in the third and then completed his double on Derek Cruz's Run Archie Run in the final event. The double took Munro to six winners during his three-month stint as a Club Jockey and, such is the way that he has fitted into the territory on his second visit, there is a big chance he will be invited back again next season for a similar spell. Munro beamed after racing and said: ''It really helps your riding when you are in the right frame of mind. ''I find this place very conducive to knuckling down and concentratingsolely on the job in hand - r Now that Successful Way has run out the mile, it would not be a surprise to see him score again. Munro rode an identical race on Run Archie Run in the last, settling him in behind the pace-setting Mascot Land before producing him with his race-winning burst at the top of the straight. Mettleman ran on for the quinella spot to complete a luckless night of three seconds for David Oughton and Mick Kinane.
