Spendthrift Farm homebred Brave Deb (Authentic) completed a big weekend for the historic farm–while adding a second graded win in two days for her sire–with an authoritative victory in the GIII Surfer Girl Stakes at Santa Anita Sunday. Spendthrift's colors were carried to victory at Keeneland by Tommy Jo (Into Mischief) in the GI Darley Alicibiades Stakes Friday and by Ted Noffey (Into Mischief) in the GI Claiborne Futurity Saturday. The farm's homebred Tamara (Bolt d'Oro), a daughter of champion Beholder, returned with a victory of her own in the GIII Chillingworth Stakes at Santa Anita Saturday.Brave Deb, who set the pace and just held on to take her one-mile debut over the Del Mar lawn last time out Sept. 5, was sent off at 10-1 Sunday. She rushed up and over from her outside post to stalk pacesetting favorite Will Happen through an opening quarter in :22.26. Will Happen had scampered away to a three-length advantage as the half went up in :45.76, but Brave Deb reeled her in approaching the stretch and the favorite had no response when the dark bay filly surged to the lead at the top of the lane. Brave Deb strode clear under a hand ride with Scratch It chasing in vain to the wire. Will Happen, a debut winner going five furlongs at Del Mar in August, faded to eighth.“She's a nervous filly,” said winning jockey Mirco Demuro. “First time I took her to the front and she got a little excited. Even in the morning-time she gets a little excited. I didn't want her to get too nervous and take her out of the race. So this time I let somebody take the lead and I kept close to him. She is a little bit funny, you can see when she was coming back she was looking around at everything. She doesn't really like to be in front. But she has a lot of speed and a lot of ability. It was perfect. The other one came close to me in the stretch and helped me keep going. She doesn't want to lose.”Winning trainer Richard Mandella added, “We were worried that the one that went to the lead would and it would turn into a sprint. We hoped our filly would settle, which she did. Mirco did a fabulous job with her.”Pedigree Notes:Brave Deb became Authentic's third graded winner and his second of the weekend, following Iron Orchard's victory in the GI Frizette Stakes at Aqueduct Saturday.Nora's Joy was purchased by Spendthrift for $175,000 at the 2018 Fasig-Tipton Saratoga sale.
