Northfield Park hosted its biggest night of racing this year on Saturday night with eight $250,000 Ohio Sires Stakes final for 2- and 3-year-old pacers and trotters going behind the gate. Driver Josh Sutton was the star of the show, winning four finals, three for trainer Jim Dailey.  Sutton won both championships for 2-year-old trotters, striking first with filly Let's Get It Started (1:57), who overcame a second turn break to win for trainer Bobby Brower, and again with colt Rose Run Spanky (1:57) for Dailey.  He joined forces with Dailey again to bag the 2-year-old colt pace with Scotch Mcewan in 1:54, and Sutton completed his grand slam with Dailey's My Tweed Heart (1:53 1/5) in the 3-year-old filly pace. While Sutton won both 2-year-old trots, Chris Page did the same thing in the 3-year-old trots, guiding filly trotter Consolidator (Chris Page) to a 1:55 1/5 tally for trainer Jim Arledge Jr., and male trotter Wegoferdaprize to a 1:56 2/5 score for trainer Jessica Millner. The 2-year-old filly pace championship would go to Berazzled (Peter Wrenn), who rallied from off-the-pace to prevail in 1:55 for trainer Danny Collins, and the 3-year-old colt pace title went home with Whataboy, a 1:51 3/5 victor for driver Ronnie Wrenn Jr. and trainer Brian Brown. In other action on the card, Scott Rocks set a new world record for an older pacing gelding on a half-mile track by winning a $20,000 open handicap pace in 1:49 for driver Aaron Merriman and trainer Chris Oakes.
