Saturday's $1.5-million day of racing at Oak Grove, which concluded the $2.75 million Festival of Racing, included four $100,000 Kentucky Sire Stakes (KYSS) finals for 4-year-olds.  Gimpanzee Dancer (Andy McCarthy) capitalized on a pocket trip from odds-on favorite Go Dog Go (Todd McCarty) bobbling off stride into the last turn to win the KYSS final for trotting horses and geldings in 1:51 3/5 over 37-1 shot Royal Comet (Marvin Luna) and 15-1 shot My Degenerate (Tyler Miller). Chris Beaver trains and co-owns the 4-year-old son of Gimpanzee-Weslynn Dancer with partners Carolina Ortiz Acosta and Derek Ivany. He won his 10th race from 35 starts, earning $439,667, and paid $10.02 to win. Harrisburg Heist (Ronnie Wrenn Jr.) motored by weary rivals to deliver as the 1-5 favorite in the KYSS final for 4-year-old pacing horses and geldings, stopping the clock in 1:48 4/5. Following a recall before the race, Wrenn Jr. sat third as stablemate Banderas (Yannick Gingras) battled with Higher Ground (Dexter Dunn) through early splits of 25 3/5 and 53 3/5. As the dust settled, Wrenn fired Harrisburg Heist off the pegs and brushed to the lead with a sharp sprint to three-quarters in 1:20 2/5. He held momentum through the lane to register a 4 1/2 length win over Banderas, with Captain Arturovico (Scott Zeron) closing for third and Fusion (Todd McCarthy) taking fourth.  Ron Burke trains Harrisburg Heist, a Downbytheseaside-Cashaway gelding, for owners Burke Racing Stable, Knox Services Inc., Phil Collura and Weaver Bruscemi. The gelding won his 15th race from 34 starts, has now earned $650,202 and paid $2.76 to win.  Three Times Bettor (Dexter Dunn) persisted through a methodical first-over push in a quick tempo to score a track-record equaling 1:48 3/5 win in-hand in the KYSS final for 4-year-old pacing mares. Dunn tipped his charge out of third after following a clip of 25 4/5 and 53 1/5 and inched comfortably towards pace-setter Odds On Chesapeake (Todd McCarthy) rolling to three-quarters in 1:20. As Odds On Chesapeake began to tire, Three Times Bettor grabbed the lead and scooted away confidently for a length win over pocket-sitter Aintnothingucando (Scott Zeron). Unreasonable (Jason Bartlett) followed the winner's cover to take third while Odds On Chesapeake held fourth.  Brett Pelling trains Three Times Bettor, a Bettor's Delight-Three Times A Lady mare, for owner Thaddeus Wier. She won her 12th race from 20 starts, earning $263,814 in her career, and paid $2.50 to win. Her 1:48 3/5 win equaled the track record for aged pacing mares set in 2022 by Blue Diamond Eyes.  ► Sign up for our FREE DRF Harness Digest Newsletter Last season's leading driver Marvin Luna orchestrated the biggest surprise of the day when he got Aperfect Annie, the longest shot on the board at 58-1, to edge by odds-on favorite Yo Tillie (Todd McCarthy) in the KYSS final for 4-year-old trotting mares. Luna procured the pocket seat to Yo Tillie passing a 27 2/5 first quarter and followed intently through a 56 2/5 half and 1:23 4/5 three-quarters. Winnpanzee (Yannick Gingras) mounted a blitz out of third to the far turn but jumped off-stride, leaving Yo Tillie seemingly to herself turning for home. McCarthy asked his charge to quicken and drifted off the pylons when reaching for the finish, giving Luna ample room to accelerate by late with Aperfect Annie and land a neck in front in a 1:52 2/5 mile. Longshots Best Friends Girl (Ronnie Wrenn Jr.) and Grand Reserve (Scott Zeron) finished third and fourth, respectively.  Carter Pinske, who led all trainers on the day with three wins, including his sweep of the Trotting Oaks consolations, trains Aperfect Annie for owners Pinske Stables, Melvin Hartman and Andray Farm. The daughter of Googoo Gaagaa-Asixpakfromperfect won her seventh race from 28 starts in her career, earning $496,514, and paid $119.62 to win.  Live racing at Oak Grove resumes on Monday (May 18) with a 13-race card headlined by a $30,000 Open Handicap Pace, carded as Race 4. With the major upset by Aperfect Annie on the Saturday card, the $1 Pick 4 with a guaranteed pool went unclaimed, leaving a carryover of $11,542.62 into the Monday sequence which covers the last four races on the program.
