How vast and varied is Steve Asmussen’s training operation?  At Churchill Downs on Sunday morning, the early favorite for the Breeders’ Cup Classic, Gun Runner, had a well-publicized workout. On Sunday afternoon, Asmussen won the $100,000 Remington Green, a 1 1/8-mile turf race, with Turbo Street, a horse he and owner Clark Brewster claimed last out for $25,000 at Saratoga. Asmussen also sent out the Remington Green runner-up, Paternal Pride, who was gaining on Turbo Street but fell a neck short at the finish. Richard Eramia rode Paternal Pride, while Ricardo Santana Jr. was aboard Turbo Street, who got an ideal trip in the pocket as No Holds Barred set a slow pace. No Holds Barred and Alex Birzer tried to open up on the far turn, but Turbo Street matched his every move, found room outside No Holds Barred in upper stretch when Lawless West drifted out, and quickened to the front. Eramia and Paternal Pride swept along in Turbo Street’s wake and had momentum, but even the race’s nine furlongs weren’t quite enough for him Sunday. Turbo Street paid $8.40 and was timed in 1:47.91 over firm turf. Net Gain finished third, while 2-1 favorite Flashy Chelsey never got involved and checked in sixth. Turbo Street is a 6-year-old on Northern Hemisphere Thoroughbred time, but was bred in Australia and campaigned there the first 21 starts of his career. Turbo Street was winless in five North American races before providing a quick return on Brewster’s $25,000 investment by taking home the $59,898 winner’s share of Sunday’s purse. Turbo Street is by Encosta de Lago and out of Extra Terrestrial, by Quest for Fame. Golden Mischief’s flashy run        Golden Mischief’s superior midstretch move propelled her to a neck victory over favored Wheatfield in the $50,300 Flashy Lady, the first of the Sunday stakes at Remington. Donita’s Ruler and Euro K Shotgun dueled on an impossible pace down the backstretch and around the turn in the Flashy Lady, and while Wheatfield had first run on the tiring pair, Golden Mischief and Ricardo Santana Jr. burst past Wheatfield at the eighth pole. Wheatfield fought to get back on terms and was narrowing the gap, but Golden Mischief got home a neck in front.   Trained by Asmussen for Bill and Corinne Heligbrodt, Golden Mischief ran six furlongs in 1:08.53 and paid $5.40 to win. The 3-year-old filly, a six-time winner now from 15 starts, is by Into Mischief and out of the Carson City mare Lanai City. *** Final Arrow lost two Texas-bred $25,000 maiden-claimers this past summer, but he won the $75,000 Kip Deville by a half-length Sunday. Final Arrow was coming off a $25,000 maiden-claiming romp Sept. 2 at Remington in his first start for trainer Andy Gladd, but not many bettors thought much of his chances, and Final Arrow paid $85.60 to win. Land Battle finished second, while favored Flat Lucky, who fell far behind the early leaders, rallied much too late and finished third. Final Arrow, by Crossbow, was ridden by David Cabrera for owner T and M Precision Services LLC.
