Twilight Eclipse, a three-year-old Purim gelding making only his sixth career start, registered an 11-1 upset of Saturday's Grade 2, $150,000 W.L. McKnight Handicap at Calder. His stalk-and-pounce rally under Manoel Cruz resulted in a 1 3/4-length triumph in a time of 2:26 3/5 for 1 1/2 miles on the firm turf.

Ioya Bigtime, the 3-2 favorite, led comfortably through splits of :25 1/5, :48 4/5, 1:13, 1:37 3/5 and 2:02 3/5. Twilight Eclipse, who rated in second passing the stands the first time and third in the second run down the backside, was poised to make a bid when only 1 1/2 lengths behind that rival approaching the quarter pole. Although Ioya Bigtime initially appeared to have run left, Twilight Eclipse easily swooped past in the stretch and drew off to a convincing win for owner West Point Thoroughbreds. Twilight Eclipse paid $24.80, $12.40 and $4.60.

Outsiders filled out the trifecta as Mucho Mas Macho, the 39-1 longest shot on the board, made a bold rally late to finish second, three parts of a length ahead of 11-1 chance Vertiformer. Ioya Bigtime retreated to fourth and was followed by 2010 McKnight winner Prince Will I Am, Manchurian High and Center Divider. Forte Dei Marmi, the 8-5 second choice, trailed the field after making an early move around the third and final turn.
