Charlotte Jacobs of East Aurora, N.Y., won the $15,000 Junior Jumper Classic on Karona V Schl'hof Ch at the Devon Horse Show and Country Fair on Saturday night, making her mount the junior jumper champion and giving Jacobs the title of leading junior jumper rider.

Jacobs won with a clean jump-off round in the quick time of 42.542 seconds over Samantha Schaefer on Trezebees, also clean in 43.160, in a seven horse jump-off.

"She's such a naturally quick horse," Jacobs said of Karona V Schl'hof Ch. "She has an enormous stride for such a little horse."

Jacobs also won the Equitation Championship on Friday and had placed in an earlier junior jumper class.

"I never imagined I would have a weekend like this at Devon," said Jacobs, who is in her fourth year of competing at the event.

"Last year I won one class, and before that got just one ribbon."

Victoria Colvin of Loxahatchie, Fla., rode both champions in her age section of junior hunters, and the judges named her best child rider on a horse.

Colvin, who rode four horses in hunters and two in jumpers, also won one of the equitation classes on Thursday.

She was champion on Sanzibar in small junior hunters, 15 and under, and on Touchdown in large junior hunters, 15 and under.

"Touchdown is fun, but he's green, he's only 6, so he spooks sometimes," Colvin said. "Sanzibar has an amazing canter; he feels like a couch."

Colvin, who trains with Scott Stewart of Flemington, N.J., the Devon leading hunter rider for the last eight years, said she planned to stay for the next week of Devon and will help Stewart, riding some of his horses in the morning to school them.
