Jason Lumpkins, Anthony Black, and Pat Day had big days over the weekend, with all three jockeys booting home five or more winners on one card at their respective tracks.On Saturday, Lumpkins rode six winners at Bay Meadows, tying a record for the track. Lumpkins became the seventh rider in the history of the Northern California track to ride six winners on the same card."It feels great," said Lumpkins after riding Rare Top to victory in the ninth and final race. "And I just got beat on another one (Wegottohaveharte, who was beaten a head by Tall American in the third race)."Lumpkins, who leads the jockey standings for the current Bay Meadows meet, has ridden six winners on the same card twice before in his career, accomplishing the feat at both Thistledown and Mountaineer Park.Also Saturday, Black guided five winners to victory at Delaware Park."You have to enjoy these successes while they are happening," said the 49-year-old Black. "The older you get the more you appreciate it and enjoy it."Five jockeys have previously won six races on one card at Delaware Park, including Michael McCarthy, who accomplished the feat on two occasions.On Sunday, Day rode five winners at Churchill Downs, winning the feature race on People's Princess after starting his five-win day with a victory on Florida Oaks (gr. III) winner Quick Tip in the third race.The win on People's Princess was Day's fourth on the card. He then went on to win the nightcap aboard Critical Battle. The all-Day late double returned $11."We dropped back after the start and just settled," said Day, following the People's Princess victory. "I found a seam at the top of the stretch and shot through there. She was the favorite in the race and she ran like a favorite should."The five-win day marked the 20th time the Hall of Fame jockey has accomplished the feat at Churchill Downs and the second time on the current meet.
