Trainer Mac Robertson won the 1,000th race of his career when Thunder and Honey won the seventh race at Canterbury Park on Saturday. Robertson, the son of trainer Hugh Robertson, apprenticed under his father for years, and though he was trainer of record for a minimal number of starters in the mid-1990s, he actually went out on his own in 2005, though even now there remains active convergence between stables of father and son. Robertson, who has based his operation at Canterbury, Oaklawn Park, and Delaware Park, had his best years in 2012 and 2013, when he won 115 and 111 races, respectively.
