Glowing caused a 20-1 upset in the Group Three Irish Stallion Farms EBF Brownstown Stakes at Fairyhouse.Always close to the generous pace set by Monivea, the Dansili filly gained a slight lead at the furlong pole under Fran Berry. Dermot Weld's Luminous Eyes (8-1) emerged from the pack as a worthy foe, but Charles O'Brien's four-year-old showed buckets of stamina to collect by a short head.Heart Shaped, fourth in the Newmarket 1000 Guineas and a close-up second in last season's Breeders' Cup Juvenile Fillies Turf, was sent off the 2-1 favourite. Aidan O'Brien's filly endured a troublesome passage along the final straight, however, and finished out of the money.Ed Dunlop's Chantilly Tiffany could never get competitive, while fellow British raider Festoso fared better but was also unplaced.
