Baker hired D. Wayne Lukas to pick some colts out at the 1996 Keeneland September yearling sale; one of those turned out to be Grand Slam. Campaigned in partnership with David Cornstein and William Mack, Grand Slam won a pair of grade 1 races (Futurity and Champagne) before running unsuccessfully in the Breeders' Cup Juvenile (G1) in 1997. The colt returned to the Breeders' Cup in 1998, finishing second in the Sprint (G1). Grand Slam is now a successful sire at Ashford Stud. Mack, who is married to Phyllis, lives in New York City and is co-chair founder and managing partner of Apollo Real Estate Advisors. He attended University of Pennsylvania's Wharton School where he serves on the Board of Overseers and as vice chairman of the Board of Trustees.

Baker and Mack currently maintain a partnership with horses in Lukas' care. They purchased Flying Private for $700,000 at the 2007 Keeneland September Yearling Sale.
