Ghostzapper was not exactly a workhorse.

He never raced more than four times in any of his four seasons.

Yet in the relatively brief time he spent on the racetrack, Ghostzapper had few – if any – peers.

In 2004, when he was named Horse of the Year, he was an undefeated graded stakes winner, versatile enough to win at seven furlongs, 1 1/8 miles, and 1 ¼ miles while registering blazing fast times in each of them.

Never underestimate a champion. This age-old lesson was reiterated to handicappers and racing fans alike when the sensational, speedy mare Groupie Doll defied age and expectations in the 2013 Breeders’ Cup Filly and Mare Sprint.
