Jockey Cliff Berry closed out his historic Remington Park meet on Saturday night by guiding Grant Jack to an upset in the season’s richest race for 2-year-olds, the $250,000 Springboard Mile. The victory came on the heels of Berry going 7 for 7 with his mounts Friday night to tie a North American riding record that was last achieved in 2006 by Russell Baze, when he went 7 for 7 on a card at Bay Meadows.
