Churchill Downs: Sum of the Parts looks to rebound in Wednesday allowance sprint

Sum of the Parts finished last of seven in his 2013 debut and will look to rebound in Wednesday's allowance at Churchil Downs.

LOUISVILLE, Ky. – Tom Amoss said he was disappointed with himself far more than with Sum of the Parts when the colt was virtually eased in his 4-year-old debut this winter.

“I didn’t have him ready enough, obviously,” Amoss said. “Since then, he’s really trained well. I think he’ll give a much better account of himself this time.”

Sum of the Parts, with Julien Leparoux to ride from post 3, is the likely favorite in the fourth and richest of 10 Wednesday races at Churchill Downs, a $61,000 allowance sprint that drew five other older sprinters. As the winner of the Grade 3 Phoenix last fall at Keeneland, Sum of the Parts is taking full advantage of the race conditions when dropping from the stakes ranks.

“He might be the fastest horse I’ve ever had from a standing start,” Amoss said. “He is exceptionally athletic.” To get back on the winning track Wednesday, “I think a lot depends on how much pressure he takes early. There is some speed to his outside, although I don’t think it’s his kind of speed.”

Sum of the Parts, owned by Klaravich Stables and William Lawrence, was a creditable fourth last fall in the Breeders’ Cup Sprint after winning the Phoenix. In his March  16 return, he faded badly as the 9-5 favorite in the Colonel Power Stakes over the Fair Grounds turf.

Clearly, the chief threat to Sum of the Parts in the six-furlong feature is Rothko, the winner of the Grade  3 Aristides here last summer. A 5-year-old horse trained by Steve Asmussen, Rothko has had nine recorded workouts since early March after finishing far back in his 2012 finale, the Grade 1 Vosburgh at Belmont Park in September. Corey Nakatani will be aboard from post 2.

The rest of the field is Scatman, Jasizzle, Off the Jak, and Why Pretend.

One other allowance is carded for Wednesday. It’s a $52,000, first-level turf route that drew a sizable field of fillies and mares, with Pavla, I’m Your Luv, and Cat’s Holiday the likely favorites.

◗ The Thursday co-features are a couple of excellent allowances, with Turallure the biggest name in either spot. Turallure is one of nine in a $61,000, stakes-caliber turf allowance that also drew the likes of Air Support, Cease, Keep Up, and Rahystrada. The preceding race is a one-turn, main-track, one-mile test pitting Golden Ticket and Bind against eight others.
