Dede McGehee's homebred ST. JOHN'S RIVER (Include) was bucking and playing in her stall Saturday morning, looking nothing like one would expect from a filly who passed every horse but one while weaving through the field in a million-dollar race. The bay lass recorded her third straight runner-up finish when just missing in Friday's Kentucky Oaks (G1) at Churchill Downs.

"Look at her," trainer Andy Leggio Jr. said at Barn 43 as St. John's River watched another horse walking around the barn. "She's peeved that's not her out there doing that. She's in great shape."

St. John's River came within a neck of catching winner Plum Pretty (Medaglia d'Oro), thanks in large part to a heady rail trip under 23-year-old jockey Rosie Napravnik that drew comparisons to vintage Calvin Borel.

"She gave her a great ride," Leggio said. "When she cut that corner turning for home I thought, we're going to win this race. But we just couldn't get there."

With a better start St. John's River very well could have won the race, but she spotted the field a few lengths by breaking to the right from her outside post.

"I think it was because she went in last and they rang the bell before she got settled," Leggio said. "She went out a little bit and that probably cost her a length just getting her straight. I think if she breaks straight she wins by two or three lengths, but that's racing and that goes with the territory."

"I wanted to get through this one first but now that this race is over and I know the kind of horse she is, I'm thinking Breeders' Cup and I'm going to try to keep her happy and healthy until that race.

The 2011 Breeders' Cup World Championships will return to Churchill Downs for the second consecutive year and a record eighth time overall on November 4-5.

"That's the time of the year when they run against older horses. Once you get to September, October, November, it's no problem," Leggio said. "We'll run her in a little race here and there but we want to make it easy on her until the big race comes along."

St. John's River will leave Louisville by van late Sunday afternoon for Leggio's summer base at Louisiana Downs in Bossier City, Louisiana.
