ARLINGTON HEIGHTS, Ill. – Streamline’s storybook ascent has been put on hold until autumn. A 4-year-old Illinois-bred filly, Streamline bounded out of obscurity this winter at Oaklawn Park, where she had an excellent four-stakes campaign that began with a win in the $100,000 Pippin and culminated with a second-place finish in the Grade 1 Apple Blossom. But Streamline exited the Apple Blossom with an injury, nothing major, according to trainer Brian Williamson, and will spend “a few months” on a Kentucky farm. Williamson hopes Streamline can rejoin his stable in August to point for a fall-winter campaign. “There’s no surgery or anything like that,” Williamson said. “I was going to give her a break anyway after I got a couple more races in her, but that’s all right, she’s been running pretty hard.” Streamline was bred by Nancy Vanier, Williamson’s mother-in-law, is co-owned by Vanier and Cartwright Thoroughbreds, and is by Vanier’s stallion, Straight Line. Streamline looked decent on turf and Polytrack last year but won a dirt allowance race at Hawthorne last fall by more than 15 lengths. “They didn’t have an allowance race for her when I got to Oaklawn, so I wound up having to run her in a stakes,” said Williamson. And that worked out pretty well in the end.
