SARATOGA SPRINGS, N.Y. – The only horse that trainer Butch Reid ran at the 2020 Saratoga meet was Vequist, who as a maiden won the Grade 1 Spinaway for 2-year-old fillies by 9 1/2 lengths. The first horse Reid will start at the 2021 Saratoga meet is Mainstay, a half-sister to Vequist who, after winning her debut by 7 3/4 lengths, runs in Thursday’s Grade 3, $150,000 Schuylerville Stakes for 2-year-old fillies at six furlongs, the co-feature on Saratoga’s10-race opening-day card. Reid had Mainstay entered in the $150,000 Astoria Stakes at Belmont on June 3 but scratched to run in a maiden race the following day at Monmouth Park. Mainstay, under Frankie Pennington, took over soon after the start and drew off in hand to dominate seven rivals in a race run over a sloppy track. The horses she beat are 0 for 4 in their next starts. “She had shown a lot of ability in the morning,” Reid said. “She drew an inside post. All she had to do was get away from there and I thought she’d be pretty tough to deal with.” Mainstay, a daughter of the Australian-bred sire Astern, has since fired two bullet works at Parx, including a half-mile in 45.60 seconds on June 23. “We weren’t looking for that,” Reid said. “The riders just sit on her. She just does it on her own.” Mainstay will again break from post 2 under Pennington. Happy Soul, a daughter of Runhappy, won the Astoria by 11 1/2 lengths, running back three weeks after she won a maiden race by 11 3/4 lengths, also at Belmont Park. Trainer Wesley Ward was initially planning to wait to run Happy Soul in the Adirondack Stakes on Aug. 8, but has been too impressed with the way she has trained lately to leave her in the barn. Ward said Happy Soul’s demeanor has impressed him the most thus far. “She’s a little bit of an overachiever,” Ward said. In his career, Ward is 0 for 34 in graded stakes at Saratoga, 0 for 30 in graded dirt stakes. One race prior to the Schuylerville, Ward runs heavily favored Golden Pal in the Grade 3, $120,000 Quick Call Stakes on turf. In the Schuylerville, trainer Tom Amoss sends out maiden winners Pipeline Girl and Cartel Queen. Pipeline Girl, a daughter of Air Force Blue, is running back in three weeks after just getting by Trade Secret to win a six-furlong maiden race by half a head. “She had to wait for room on the turn and angle out and did a lot of things she should benefit from as far as education goes,” Amoss said. Jose Ortiz rides Pipeline Girl from post 3. :: Bet the races with confidence on DRF Bets.

Cartel Queen, a daughter of Cairo Prince, has run twice, winning a five-furlong maiden race at Churchill after finishing second at first asking. Despite the victory, Amoss is adding blinkers to Cartel Queen’s equipment for Thursday’s race. “She was fairly intimidated being in tight quarters,” Amoss said. “After that race we practiced with blinkers quite a bit and it was a benefit.” Also a benefit is having Irad Ortiz Jr. aboard from the outside post. Pretty Birdie, a daughter of Bird Song, won at first asking for Norm Casse and owner John Hendrickson, who is carrying on Marylou Whitney’s racing stable. That June 18 race at Churchill produced two next-out winners in maiden special weight company at Ellis Park. Trainer Steve Asmussen is a three-time Schuylerville winner. He entered Velvet Sister, a New York-bred daughter of Bernardini who beat just two opponents in an open maiden race at Belmont on June 10, and Eagle Express, a Texas-bred who won a Texas Stallion Stakes as a maiden at Lone Star on June 13. Queen Camilla, a second-out winner at Gulfstream for Antonio Sano, and Saucy Lady T, a second-out winner at Belmont for James Chapman, complete the field.
