Jerry Hollendorfer became only the fourth Thoroughbred trainer to win 6,000 races when Just Tappin It won the sixth race on Saturday at Golden Gate Fields, a $4,000 claiming race.
Russell Baze, who has ridden more than 2,500 winners for Hollendorfer, was aboard.
Hollendorfer and Baze are both in the Hall of Fame.
Just Tappin It ended a streak for Hollendorfer in which he had won with just one of his previous 35 runners.
