It was advertised as a great race and the Grade 3, $150,000 British Columbia Derby at Hastings didn’t disappoint, with the three favorites hitting the wire together. With Rico Walcott aboard, Chief Know It All emerged the winner by a nose over Trooper John in the 1 1/8-mile race. Riser set an honest pace under pressure and held on well to finish a neck behind Trooper John. Chief Know It All paid $9.50. Chief Know It All was claimed by trainer Robertino Diodoro for $100,000 at Churchill Downs on June 30. In his first start for Diodoro and owners Rollingson Racing Stable, Randy Howg, Rick Wiest, and Clayton Wiest, he won the Grade 3, $150,000 Canadian Derby at Northlands Park. “What a great group of owners,” said Diodoro. “They really stepped up to the plate. And what can I say about Rico. I told Bob if I couldn’t get Rico for the Canadian Derby, he wasn’t coming.” He was referring to Walcott’s agent Bob Fowlis. Walcott had Chief Know It All saving ground while stalking the leaders most of the way. He commenced his bid at the top of the stretch and wore down Riser in the last few yards while holding off a strong late move from Trooper John.  Riser was under pressure from More Power to Him while setting quick interior fractions of 22.80 and 46.76 seconds over the sloppy going. He was game in defeat while giving way grudgingly. Trooper John was mid-pack early, starting to move into serious contention approaching the third turn, was full of run while going wide around the turn, and just missed. “I wanted to be outside of horses because ‘Tino’ told me horses were struggling on the inside,” said Walcott. “Going down the backside, Riser started to get away, so I had to go after him and I had to stay on the rail. When we turned for home, I thought I could get Riser and when I did I saw Trooper John coming. I didn’t know who won. I was thrilled when the outrider came and told me I had won.” He was referring to Hastings exercise rider Bailey Heggie, who conducted a post-race interview while the horses were pulling up. The final time was 1:51.95. The winner’s share of the purse brought the Kentucky-bred son of Flashy Bull’s career earnings to $317,006. Diodoro, fourth in wins among trainers in North America, wasn’t sure where Chief Know It All would show up next.
