COLUMBUS, Neb. - Donnaguska seized a short lead after a half mile then finished with authority to score by 5 1/4 lengths in the $10,850 Bill Callihan Stakes for older fillies and mares on Saturday night at Columbus. \r\n\r\nDonnaguska made a looping move to contention through the first turn of the 6 1/2-furlong race to challenge outside Lady Countdown. She moved clear through the far turn, then drew off to shake a bid from Plaer's Trump and score her second straight victory at the track. Trained by Joe Woodard, Donnaguska returned $7 as the 5-2 favorite in the field of six. Bettors figured that every horse in the field had a chance, with 6-1 the longest price on the board.\r\n\r\nDonnaguska had previously won a middle-level allowance race here, defeating last weekend's Maturity-Matron Stakes winner Ms. Bumper. Plaer's Trump, second in last weekend's stakes, was again second while Enchanting held third. Damon Leeds was aboard Donnaguska, as she improved her career mark to 5-2-2 from 15 starts and earnings of $64,457. She covered the distance over a fast track in 1:20.60.
