City Cool gave trainer Steve Asmussen a fourth win in the $100,000 Riley Allison Futurity since 2001 on Tuesday, when he pulled away by 7 1/4 lengths in the 2-year-old stakes at Sunland Park. City Cool ($5.60) broke on top in the 6 1/2-furlong race and proceeded to lead the field through an opening quarter in 22.45 seconds. Lion Hall moved up to press him from the inside, with City Cool continuing to maintain his advantage through a half-mile in 45.22. Into the stretch, City Cool gave Lion Hall the slip and went on to cover the distance on a fast track in 1:15.53. Ken Tohill was aboard for owner Mike McCarty. City Cool earned $64,320 for his win Tuesday, which was his second from five career starts. He was an 8 1/2-length maiden special weight winner at Churchill Downs on Oct. 31. City Cool, a son of City Zip, has now earned $111,948. It’s My Party closed from well back for second, with R Skydiver finishing third. Asmussen also won the Riley Allison in 2009 with Grand Slam Andre, in 2008 with Retap, and in 2001 with Interminable Gold.
