GER Lyons believes Colin Keane still has his "work cut out" to be crowned this year's champion jockey despite stretching his advantage with a double at at Roscommon on Tuesday.

The young rider leads nine-times champion Pat Smullen by eight winners - 53 to 45 - following victories on the Lyons-trained pair of Ball Girl in the fillies' maiden and Cannonball in the 10-furlong conditions race.
