ETOBICOKE, Ontario – Natalma Stakes winner Conquest Harlanate will switch to Polytrack to gain two-turn experience in Sunday’s Grade 3, $150,000 Mazarine Stakes at Woodbine in preparation for the Breeders’ Cup Juvenile Fillies Turf at Santa Anita on Oct. 31. Conquest Harlanate captured the Grade 2 Natalma Stakes by a neck over Isabella Sings in her last start Sept. 13 over Woodbine’s one-turn mile. Trainer Mark Casse said it is important for Conquest Harlanate to gain experience around two turns before heading to California. “What I’m trying to do is get a two-turn race into her so she gets some two-turn experience,” he said. “We already know she can run on the grass, but the one thing she’s going to have to do differently in the Breeders’ Cup is run around two turns.” :: DRF Live: Get real-time updates and insights from DRF reporters and handicappers starting at 12:30 p.m. ET on Sunday Casse said Conquest Harlanate is coming into the Mazarine in good order on the strength of a five-furlong breeze here in 1:02 last Saturday, but he did note that turf might be her preferred surface. “She’s good,” he said. “She didn’t have to do much. There’s a chance she’s not as good on the synthetic as she is on the turf.” KEY CONTENDERS Conquest Harlanate (Last 3 Beyers: 76-70-55) DRF FORMULATOR FACT: Over the past five years, Casse has a 25 percent strike rate with horses going from turf to synthetic in graded stakes, with a return on investment of $2.25. :: Learn more about Formulator | Follow the @DRFFormulator Twitter feed and get free Formulator facts Dixie Twist (Last 3 Beyers: 55-65-57) ◗ One of three fillies in the field trained by Casse, Dixie Twist was well off the pace in the Natalma but did appear to run well in the late going. ◗ She has strong form on Polytrack, having won the Ontario Debutante Stakes in August, and she should appreciate the stretch-out. Roaming (Last 3 Beyers: 38-65-59) ◗ Roaming will be looking to bounce back off a disappointing showing in the Natalma. She’s already defeated Conquest Harlanate on Polytrack this year and nearly won the Ontario Debutante over Dixie Twist. DRF FORMULATOR FACT: Over the past five years, trainer Gail Cox has won 24 percent of her starts with horses going from turf to synthetic, for an ROI of $2.87.
