Trainer Mike Trombetta swept Saturday’s pair of juvenile turf sprints at Colonial Downs, as both the Estate of Larry Johnson’s colt Doubting Thomas and Red White and Blue Racing and London Reid Thoroughbreds’ filly Just Philtored wired their respective Virginia-bred, -sired or -certified fields in the $125,000 Jamestown and $125,000 Dolley Madison.

With Jorge Ruiz aboard, Doubting Thomas covered 5½ furlongs in 1:02.39, defeating Karate Island by 1¾ lengths. Sometime finished third.

“I was loaded at the top of the stretch and waited until they made a run at him before opening him up,” Ruiz said. “Today he broke spiritedly from the gate, so I said, let’s go to the lead. I like this horse — he is maturing nicely.”

The odds-on favorite Doubting Thomas paid $3.00, $2.10 and $2.10.

Along with his off-the-pace debut win, the Virginia-bred Caravaggio colt is 2-for-2 on turf with a career bankroll of $127,500.

Going 5½ furlongs under jockey Mychel Sanchez, Just Philtored stopped the clock in 1:03.21 while winning the Dolley Madison by 4½ lengths over Slewperstitus. Karina Anna ran third.

“You can do anything with her,” Sanchez said. “I didn’t see a lot of speed in the race, so I took advantage of that and went to the lead. Although we put up a good time, I feel like she went a little slow for what she wanted to do. I can rate her more, I can send her more. Bodywise, she is strong. When you get on her, you can feel the power.”

Sent off as the 7-5 favorite, Just Philtored returned $4.80, $2.60 and $2.10.

Perfect in three career starts, including the Keswick, the Maryland-bred daughter of Great Notion has earned $167,430.
