A full field of 10 older fillies and mares lined up behind the starter for the $250,000 Breeders Crown Open Mare Trot. Buck I St Pat was sent off as the 6-5 choice over 2-1 Maid for Tag and 8-1 Classic Lane. 16-1 Falls for You was wide around the clubhouse turn on the front end through a quarter of 27 4/5. Classic Lane moved up to take over the lead down the backstretch through a half in 55 1/5 and 3/4 in 1:24 1/5, leading the field to the top of the lane. However, Buck I St Pat, who sat in 4th wide early, closed well to take over the lead in midstretch and drew away to win by 3 lengths over late-running 20-1 Lavec Dream in a stakes record time of 1:52. It was another 4 3/4 lengths back to Spice Queen third.
Her driver Tim Tetrick said, "She can just absolutely fly when she's on her game. She can get off someone's helmet like a pacer. She's just amazing." Buck I St Pat, a 6-year-old daughter of Jailhouse Jesse, has a record of 10 wins in 14 starts, with earnings of $1.2 million. Trainer Ron Burke said, "This is our first Breeders Crown and hers, so it's big for us, too."
