ARCADIA, Calif. – Beholder was allowed to rock and roll Wednesday at Santa Anita, where she posted a dazzling five-furlong work in preparation for the Grade 1 Vanity Mile on June 4. Trainer Richard Mandella gave exercise rider Janeen Painter permission to let Beholder rip through the stretch, and the three-time champion obliged with a 22.60-second final quarter on Mandella’s watch. “We don’t do that often with her, especially when she’s ready,” Mandella said. “But she needed something, and you don’t want her getting complacent.” Complacency is rarely an issue for Beholder, a 16-time winner from 21 starts. But the competition will be tougher when Beholder makes her second start of the season in the Vanity, and Mandella turned it up a notch Wednesday. It was 7:45 a.m. when Beholder broke off at the half-mile pole behind another worker. She cruised the first eighth in 13 seconds, collared her work rival on the turn with a quarter-mile in 24.60 seconds, blazed to the wire in 47, and worked out to the seven-eighths pole. Clockers gave Beholder a time of 59.40, breezing. “I think she’s doing pretty good,” Mandella said after the work. It was a deliberate understatement. Beholder already has reached top form after just one start this season. The 6-year-old mare won the Grade 3 Adoration Stakes on May 8, worked an easy half-mile May 19, and will breeze another easy half early next week. Bring on the challengers in the Vanity. “It’s going to be interesting in that there will be different players,” Mandella said. “Taris and them, they are good fillies. They’re fast and fresh.” Taris, the winner of the Grade 1 Humana Distaff on May 7 at Churchill Downs, is not a confirmed starter in the Vanity, however. Trainer Simon Callaghan said Wednesday she could skip the Vanity and face males June 25 in the Grade 1, seven-furlong Triple Bend here. Stellar Wind, the champion 3-year-old filly of 2015, is scheduled to make her 2016 debut in the Vanity. Lost Bus, the upset winner of the Grade 2, seven-furlong Santa Monica, could stretch out for the Vanity, according to trainer Gary Sherlock. Finest City, the winner of the Grade 2 Great Lady M., also is under consideration. Beholder, who has earned $4,496,600 and won seven straight, will be tough to beat. Mandella said Wednesday, “She’s in a different world.”
