Jockey bookings suggest that ECLIPSE CHASER is the Willie Mullins first-string and he is taken to make a winning Rules debut. The 4-y-o appeared to be holding all the aces when coming down at the second-last on his sole start between the flags in March. American Jukebox should come on for his spin at Fairyhouse last month and, with this stiffer test likely to be in his favour, he is feared most ahead of Eclipse Chaser's stablemate Leaky Cauldron. God Help Me is also shortlisted.
