ETOBICOKE, Ontario – Dynamic Sky closed five wide under Joel Rosario and caught 12-1 shot His Race to Win late to win Sunday’s $150,800 Plate Trial Stakes, an important prep for the July 7 Queen’s Plate at Woodbine. Dynamic Sky ($8.60) bided his time near the back of the 10-horse field in the 1 1/8-mile route, as Midnight Aria and Holy Whirl Wind vied through honest fractions. Dynamic Sky commenced his rally on the far turn in unison with a four-wide His Race to Win, who hit the front in midstretch before Dynamic Sky nailed him on the wire to prevail by a nose in 1:50.59. Midnight Aria weakened late but held on for third over the wide-closing favorite, Pyrite Mountain, who galloped out in front. Trainer Mark Casse took the blinkers off Dynamic Sky for the Plate Trial. “I thought he’d have a good chance,” Rosario said.  “He’d been running with top horses. [Casse] took the blinkers off, and I think it made a difference because I could get him more relaxed and do exactly what I wanted to do with him.” Dynamic Sky earned $90,000 for last year’s Sovereign Award-winning owner, John Oxley.
