Alsatian ($9.60) won for the second time in his 13th start in Saturday's fourth race, the first leg of a pick six that drew a pool of $429,011.
The pick six began with two carryovers - $65,924 in the main pool and $311,541 in the single ticket jackpot pool.
Alsatian is trained by Neil Drysdale. The 4-year-old colt, owned by Calumet Farm, was second in the Snow Chief Stakes for Cal-bred 3-year-olds last May.
