Trainer Phil Serpe expected Weekend Hideaway to run well in Wednesday’s David Stakes for 2-year-old New York-breds. What he didn’t expect was to see the son of Speightstown run six furlongs in 1:09 and change and dominate the race by more than a half-dozen lengths. But that’s the way this summer has gone for Serpe, who has sent out seven winners from just 27 starters, equaling his total for 2011 with several days still left in the meet.
