CHAMPIONSHIP-chasing Tony Cruz notched a welcome double at Sha Tin yesterday to leave himself just one adrift of triple defending champion Basil Marcus in the standings. The local riding idol took the Sandown Park Challenge Cup on the John Moore-trained Master Eagle before landing the seventh on Make Merry to help second-season handler, Stephen Leung, to a career-first treble. Sandwiched between was a highly promising run from Moore's Makarpura Star in the Classic Trial and this New Zealand import led to Cruz leaving the course with a fourth Derby uppermost on his mind. 'Yeah, it's been a real good day,' agreed Cruz. 'I've won a couple, I'm closing on Basil and I think I've got as good a chance as any of winning the Derby. 'I was pleased with Master Eagle as he can become a bit temperamental. You have to keep him relaxed so it was good to be able to switch him off today. 'I then found the split when I wanted to and he kept on well enough to the line though I just thought he was stopping that last little bit.' Moore intends to run Master Eagle in the Derby. There has to be a big question mark over whether this English import will handle the move from yesterday's 1,400-metre trip over the short straight to the 1,800 metres of the Derby where they run down the full length of the Sha Tin straight. 'I would have to say that I've got doubts about his ability to stay the trip,' was Cruz's frank assessment. But no one could possibly blame Master Eagle's connections from having a crack at the Derby. After all, it is the most important race on the domestic calendar and you only get one crack at it. If you're not in it, you can't win it, that's for sure. Moore will offer the ride to Gerald Mosse and failing that to Gary Stevens as the jockeying for Derby mounts starts to swing into top gear. Mosse has also been offered the ride on Amza Glory, for whom Darryll Holland is standing by should the Frenchman reject David Hill's gelding. Holland himself won the Classic Trial on Bogie's Pride, who will probably have a crack at the Derby, while Stevens would surely be potty to get off Electric Flash who ran such a tremendous race to be third in the Trial, having covered heaps of extra ground. Cruz's ride on Make Merry in the seventh simply oozed class as he had him balanced and travelling well all the way and only had to press the 'go' button in the straight to run down Nickels King.
