North America's fastest 2-year-old, from a Beyer Speed Figure perspective, at least, saw the sun rise Sunday morning from her stall on the backstretch at Canterbury Park.

Amy's Challenge won the $80,000 Shakopee Juvenile Stakes on Saturday at Canterbury by three-quarters of a length over Mr. Jagermeister. The win margin wasn't much, but there were six other horses in the race, including Soul of Discretion, who'd won in a romp first out with an 85 Beyer, and Mr. Jagermeister finished 18 lengths in front of the third-place horse. Eighteen lengths! Amy's Challenge clocked 1:09.58 for six furlongs, which was .44 seconds faster than the winning time one race earlier in a $50,000 stakes for older horses, and was good for a Beyer of 92. That's one point higher than the 91 Amy's Challenge earned romping in her career debut, and gives her the two highest Beyers assigned to a 2-year-old so far this year in North America.

"There’s no question about the validity of the number, even though it’s a little surprising to see a horse of this quality emerge at Canterbury," Andy Beyer wrote in an email Sunday morning.

Beyer said that, if anything, the figure from the Shakopee Juvenile could've been higher. Mr. Jagermeister, who poked his head in front of Amy's Challenge in upper stretch, got a 90 Beyer, one of only five 2-year-old figures so far this year of 90 or greater. Mr. Jagermeister is not just a fast 2-year-old in his own right, but an extremely fast Minnesota-bred 2-year-old.

Here's another thing to ponder. Mac Robertson, who trains Amy's Challenge for the Novogratz Racing Stable, said the filly got tired late in the race in part because she had not been trained hard for Saturday's run. The plan all along had been to use the Shakopee Juvenile as a springboard to the Grade 1 Alcibiades Stakes on Oct. 6 at Keeneland, and Robertson wanted his horse to improve coming out of the race rather than going into it. And the plan might have worked! While Amy's Challenge got another big number, it was nearly identical in speed-figure terms to her first race. It remains to be seen how far Amy's Challenge carries her speed (she has the body type, stride length, and pedigree to go a route of ground), but it's not impossible these two races could take the filly to an even higher level.
