Whisper Not ($4.80) wore down Grade 1-winning mare Keeper Ofthe Stars through a head-bobbing stretch duel to win the $251,350 Grade 3 San Francisco Mile in the featured race of the six-stakes Gold Rush Weekend on Saturday at Golden Gate Fields. The 4-year-old British-bred son of Poet's Voice was favored, but his running style was a revelation. Coming off a Santa Anita allowance victory, he opened a 10-length lead down the backstretch, but was content to let longshot Diamond Blitz employ similar runoff tactics while sitting in third just outside Keeper Otthe Stars. He has hit the board in all five starts since coming to the United States and ran third with a stalking trip in the Grade 2 Mathis Brothers Mile in his second start. :: Bet horse racing on DRF Bets.

I was cheering down the backstretch because he was rating and was still relaxed,” trainer Richard Baltas said. Whisper Not ranged three wide into the lane as he and Keeper Ofthe Stars turned the stretch into a match race. They finished two lengths in front of Restrainedvengence, who rallied late to edge Brown Storm in a photo for third. Whisper Not's first stakes victory earned $150,000 for Christopher Dunn, Jeremy Peskoff and recent new owners Electric City Racing and Madaket Stables. Golden Poppy ($75,450) Altea ($12.80) scored her first victory since a November 2019 allowance win at Aqueduct and scored her first stakes win as she held off favored Red Lark by a neck in the 1 1/16-mile turf race. A comfortable third behind the dueling Colonial Creed and Northwest Factor, she made a strong, three-wide move into the lane to go past the tiring leaders and had enough left to hold off the late-running Red Lark by a head under Kyle Frey. She earned $45,000 for owners My Racehorse and trainer Mike McCarthy and lifted her career earnings to $350,164 with her third victory in 27 career starts, although she had run second in three stakes and had multiple graded stakes placings. California Derby ($101,350) Getting a trip similar to Altea's, Striking Shadow ($16.20) outdueled stablemate Jimmy Irish through the lane to score a half-length victory in the 1 1/16-mile race for 3-year-olds. Jimmy Irish, making his second start after winning a 5 1/2-furlong race in his debut, set the pace over the odds-on favorite as they were well clear until the eighth pole. Evin Roman got Stalking Shadow rolling and finally wore down his stablemate, earning $60,000 for Tommy Town Thoroughbreds and trainer Jonathan Wong. :: Get DRF Clocker Reports for the Kentucky Derby and Oaks cards to access exclusive insights from morning training California Oaks ($77,700) Favored Pizzazz ($7.20), stakes-placed while still a maiden but last in her most recent stakes start, gave Frey his second stakes victory of the day, opening up in the lane and then just holding off Freedom Flyer by a head in the 1 1/16-mile race for 3-year-old fillies. She sat off early pacesetter Empire House and took over in the lane as that one faded. Freedom Flyer rallied gamely before falling just short as Pizzazz earned $45,000 for owners Perry and Ramona Bass and trainer Richard Mandella. Camilla Urso ($77,250) Gypsy Spirit ($62.80) scored the day's biggest upset with a late rally to win the five-furlong turf sprint, rolling to a 1 1/2-length victory over favored Acting Out once she got clear in the stretch. Eighth early, she moved up nicely under Edwin Maldonado and got an opening while four wide and easily took command of the race. The British-bred daughter of Gregorian earned $45,000 for owners Red Baron's Barn and Rancho Temescal and trainer Leonard Powell with her first stakes victory and second win in the United States. Lost in the Fog ($76,350) Anyportinastorm ($12.60) became a repeat winner in the six-furlong sprint, subduing pacesetting Bettor Trip Nick and scoring an uncontested 2 1/2-length victory over former stablemate Baja Sur. Winning for the fifth time to go along with a pair of thirds in seven starts here, he got a perfect stalking trip under Roman in scoring a repeat of his 2019 victory. The race was not run last year, when he did win the six-furlong Oak Tree Sprint at Pleasanton for his last victory. The win was worth $45,000 for owner Peter Redekop and trainer Peter Miller. :: DRF's Kenucky Derby Headquarters: Contenders, latest news, past performances, analysis, and more
