Trainer Erv Miller and driver David Miller each netted hat tricks in Reynolds action for 2-year-olds of both sexes and gaits on Sunday afternoon at Tioga Downs. The Millers joined forces for two victories, winning the opening $40,450 division for colt trotters with Keystone Apache (1:57 2/5) and then the second of two $33,250 sections for colt pacers with Karpathian Kid (1:54 2/5).  Keystone Apache, an Explosive Matter colt, is also owned by Erv Miller, along with Tangie Massey, and Karpathian Kid, a colt by Somebeachsomewhere, is owned by his breeders David and John Prushnok along with David J. Miller and Lawrence Means. Erv Miller also won the other colt trot test with Farsetti Hanover (1:57 1/5), who was driven by his son Marcus, and David Miller bagged the other colt pace tilt with Closing Statement (1:53 4/5) for trainer Joe Holloway.  Farsetti Hanover, a Donato Hanover colt, is co-owned by Erv Miller, George Golemes, and David Prushnok, and Closing Statement, a colt by Somebeachsomewhere, is owned by Val D'Or Farms, Rojan Stables, and Ted Gewertz. Corey Callahan drove the pair of Reynolds victors that the Millers didn't grab, guiding John Butenschoen trainee Bill's Lady to a track record-equaling 1:55 1/5 score in the lone $64,700 dash for filly trotters and Ross Croghan-trained I'm Trigger Happy (1:53 2/5) to a score in the sole $45,300 filly pace contest.  Bill's Lady, a daughter of Donato Hanover, is owned by William Wiswell and M And L of Delaware LLC., while I'm Trigger Happy is owned by Let It Ride Stables Inc.
