TORONTO, November 29 - Jockey Justin Stein guided 17-1 shot Parabola to an upset victory in Saturday's $125,000 Kingarvie Stakes at Woodbine.

The 1 1/16-mile event for two-year-old Ontario-sired colts and geldings was the first stakes score for the cleverly-named son of Trajectory.

Ninth at the five-sixteenths pole, the Barb Minshall trainee started a strong move on the second turn and seized command with one sixteenth of a mile remaining. He outfinished determined multiple stakes-winner Mean Green for a half-length tally. Wildcat Fashion, who was on the lead early, stayed on for third.

Parabola traveled 1 1/16 miles in 1:45.32.

"I hadn't moved on him yet and he was still pulling on me pretty good when we straightened out. I got a clean run through the lane. He kicked on nicely. I knew we were in good shape at that point," said Stein. "He's a pretty decent two-year-old. He's well-developed and professional."

The chestnut gelding is owned by Janet Jeanpierre, who also bred the Ontario-bred.

Parabola broke his maiden in a maiden for Ontario-sired runners on November 6. The gelding could have been acquired on October 18, one start earlier, for a $25,000 claiming tag.

"I took a chance dropping him off the layoff," said Minshall. "He's a little goofy in the paddock and I thought nobody would take him. I told Janet (Jeanpierre, owner) that I thought he would win that day. He ran green."

Minshall, who finished second in the 2003 Kingarvie with Spider Canyon, was optimistic about Parabola's chances in the 2008 renewal.

"He had worked twice after his last race really, really well. I knew he would stay the trip," she said.

According to Minshall, Parabola can be a handful because he likes to be difficult, not because he's showing nerves.

"I wouldn't say he's nervous. He just wants to be hard-headed and wants to test you all the time," she said.

The gelding is now 2-for-6 with $122,300 in earnings.

Parabola returned $36.80, $15.40, $8.20, combining with Mean Green ($8, $4.90) for an exactor worth $327.60. Wildcat Fashion ($5) rounded out a triactor worth $2,144. Fourth-place finisher Flip for the Coin completed a $1 superfecta worth $5,222.85.
