Alan posted a sharp analysis of the Florida Derby over on Left at Gate, noting that the Beyer speed figure of 93 given to Dialed In for the just-there win “is a good 6-8 points lower than one might like to see from him at this point.” It is, but the figure is also one that’s become quite typical of Derby prospects.
If you look at the Beyer speed figure earned by each Derby starter in their final Kentucky Derby prep (column PR-BSF in the spreadsheet below) from 1998-2010, you’ll notice a pretty steady decrease in the number of 100+ BSFs appearing in prep past performances. In 1998, only two starters had not earned a triple digit figure in their final prep or in one of their two prior starts as a 3-year-old (columns 2ND and 3RD below). In 2010, only two came into the Derby with a BSF of 100, and only three — Devil May Care, Sidney’s Candy, and Jackson Bend — had even earned a BSF of 100 in their careers.

As a group, the average Beyer speed figure earned by Derby starters in their final Derby prep has declined from 101 in 1998 to the low 90s in recent years:
Average Kentucky Derby field last-out BSFs, 1998-2010.
This year, only six Derby prospects have rated a BSF better than 100 as 3-year-olds, and only The Factor (103, Rebel) and Soldat (103, allowance) have done so at a distance greater than a mile. With the Wood, Illinois Derby, and Santa Anita Derby all this weekend, it’s likely at least one winner will break through with a solid triple digit figure. Eskendereya did so in 2010, getting a 109 in the Wood, a figure that would have stood out in Derby entries if he hadn’t sustained a career-ending injury before he could get to Churchill. It wouldn’t have done much for the field average, though, which was a mere 93.
