The Rule
The one Kentucky Derby rule still going strong is that the Derby winner raced as a 2-year-old. It’s been so every year since 1882. I took a quick look at that record last year, when Verrazano was the unraced-as-a-2YO Derby contender, noting that since 2003, only nine of 192 Derby starters hadn’t raced as a juvenile (that’s now 10 of 211). It’s a small group. Nicole Sauer dives deeper into the numbers, looking at all graded stakes starters from 1973-2013:
During this period, 73% of graded stakes starters raced at age 2, while 27% were unraced as 2-year-olds. If “having a 2-year-old foundation” is important for graded stakes performance at 3, then we should expect a higher proportion of 3-year-old graded stakes winners to have raced at 2. This is the case, but only by a 2.2% margin: 75% of 3-year-old graded stakes winners raced at 2 compared to 25% who didn’t.
So, there’s a slight edge to having juvenile experience. A very slight edge.
Hoppertunity is the sole likely Kentucky Derby starter this year who didn’t race last year. If you like him, though, you have to like that he’s made up for that lack of early experience with five starts so far this year.
