Baker, Robert C. and Mack, William L.

Bill Mack and Bob Baker, for whom Hall of Fame trainer D. Wayne Lukas has trained for more than two decades, own 2013 Hopeful Stakes winner Strong Mandate.

Mack and Baker raced 2002 Kentucky Derby runner-up Proud Citizen in partnership with David Cornstein.

Mack and Baker also raced 2010 Derby seventh-place finisher Dublin and 2009 Derby runner Flying Private.

“These guys, Bill Mack and Bob Baker, have been with me 25 years. We've gone through a lot,” Lukas said. “We only buy two or three a year. Most years two, this year we got three. They've stayed with us. We've had Grand Slam and Dublin down through the years, and Scorpion. We got some nice horses, but I don't know if we've had one this good. [Strong Mandate] is a pretty good horse.”
