Its Game On for Kentucky Derby winner Street Sense.

Thats the only message one can glean from his five furlong workout yesterday at Churchill Downs. Five-eighths in 1:00 was perfect, said trainer Carl Nafzger. Who can argue?

Street Sense seems to lend new meaning to the term push-button. If you need five furlongs in :58 2/5, his first speed work following the slowly run Blue Grass, he gave it to you.

If you wanted something slower Derby week, because the colt already was there, you got that, too. Five furlongs in 1:01, following a half-mile in :49 4/5, with a gallop out past the wire in :12-flat. Pluperfect.

And now another brilliant move; fast enough but not too fast. Following an opening quarter mile of :25, it was :35 seconds home for the final three furlongs. Sharp! It appears that Nafzger still has not reached bottom. Good thing for his fans, too bad for fans of his rivals.

The dynamics of the Preakness are such that this race, despite having half the number of Derby entrants, is the greater challenge. If the fates allow that he would be the first Triple Crown hero since Affirmed, this is the race that would stop him.

The Preakness should come right down to the wire. The post position draw is 4:30 p.m. today. Can't wait.
