HOT SPRINGS, Ark. - Curlin showed maturity beyond his experience Saturday at Oaklawn Park, when he took command of the Grade 3, $300,000 Rebel Stakes in his second career start and went on to a 5 1/4-length win over Officer Rocket. It was another 2 1/2 lengths back in third to Teuflesberg, while favorite Flying First Class finished eighth. The Rebel was a prep for the Grade 2, $1 million Arkansas Derby here April 14, which is the next goal for Curlin, said his trainer, Steve Asmussen.
