Pacific Classic Stakes
The primary conduit for the continuation of Seattle Slew's male line has been through A.P. Indy, who was the leading sire in North America of 2003 and 2006. A.P. Indy sired the 2003 Horse of the Year, Mineshaft, Preakness Stakes winner Bernardini and Belmont Stakes winner Rags to Riches. A.P. Indy's grandsons include Tapit. the leading North American sire in 2014, 2015 and 2016. Slew City Slew was also a good sire, whose sons include California champion Lava Man. In 2006, Lava Man became the first horse to win the Santa Anita Handicap, Hollywood Gold Cup and Pacific Classic Stakes in the same year.
