Wise Dan’s Return

The Horse of the Year is set to make his first start of 2014 today, and:

“If he is going to be vulnerable, this is it because the others that are in there have been running,” [trainer Charlie] LoPresti said.

True, but he’s also a returning champion. The odds are good that he’ll win. In 2010, I found that returning champions beat the winning favorites average by a significant margin when they made their first starts of a new season.

The stats for returning champions are now updated through 2012: You can view the numbers and complete spreadsheet via Raceday 360. There are a couple of changes in this year’s version: I restricted the data to only starts made in North American races with wagering (horses who returned in non-wagering exhibition races and foreign races were excluded, as were steeplechase champions). I also broke out the numbers by division and decade this year, as well as by class, which revealed a few interesting tidbits.

One thing I left out of the R360 post, but wanted to make note of, is that all champions, not only the favored, won or finished in the money in 186 out of 228 races (or 82% of starts). Be sure to include them in your exotics.

The original data, including all champions named from 1971-2012, and not only those who returned to race, can be downloaded as an Excel file.

4/12/14 Update: And Wise Dan wins the Maker’s 46 Mile by three-quarters of a length over Kaigun. Here’s the returning Horse of the Year chart, updated:

That brings the returning HOTY record to 18 wins from 23 starts (18 wins from 22 favored), for a total payout of $49.10 on $46 bet.

Returning HOTYs

When Wise Dan makes his first start of the year at Keeneland on April 12, don’t bet against him. Returning Horses of the Year are 16 for 21 since 1972:

Favored returning HOTYs are 16 for 20. With a return of $43.50 on $40 bet, that makes favored returning HOTYs just about the surest bet in racing.

(The chart above is an updated version of one that appeared in a lengthier post about betting returning champions in March 2010.)

Returning Champions

March 30, 2019 Update: Hello, and thanks for visiting. If you’ve landed on this page via Horse Racing Datasets, or after reading “The Skeptical Handicapper,” by Barry Meadow, please note that while the post below was published in 2010, the spreadsheets referred to have been updated through 2017. You can view the current Google Doc or download an Excel file.

Noting that Kelso went to post as the favorite in four out of five of his returns as reigning Horse of the Year, commenter o_crunk remarked:

It makes me wonder if returning champions who go off favored in their return beat the average win percentage of favorites?

It turns out that, yes, favored returning champions do beat the average.

Champions from 1971-2008 (excluding steeplechase horses) made 210 first starts back the year after being honored, going to post favored in 177 of those races (84%) and winning 105 times (59%), a rate well above the standard 33.3% (or the 2009 average of 36.6%) As usual, the public is astute: All returning champions averaged odds of .97-1, but favored returning champions averaged odds of .68-1. Betting $2 to win on each favored champion would have returned $321.10 $285 to $354 wagered.

(View the spreadsheet/download the spreadsheet.)

A few observations based on quick analysis:

Thirty-nine champions returned in ALW/AOC company, winning 26 (66%) of those races. No champion not favored — with the exception of 2008 juvenile champion Midshipman, returning in a 2009 Belmont AOC — won at this level.

Fifty-two champions returned in ungraded stakes, winning 30 (57%) at average odds of .84-1. Only two, out of five, not favored won, but betting $2 to win on those five would have returned $13.20 to $10 wagered.

Most champions returned in graded stakes, winning 49 (41%) of 119 starts. Of the 98 that were favored, 44 won (45%) at average odds of .80-1.

Including Rachel Alexandra, returning Horses of the Year since 1971 (see chart below) made 20 starts. Favored in 19 races, they won 15 (79%) at average odds of .40-1. Betting only favored HOTYs would have returned $41.40* for $38.

*Only with a little luck would a player be on the plus side. John Henry, the highest-priced favored returning Horse of the Year, finished second in the 1982 Santa Anita Handicap and was bumped to first by the disqualification of Perrault. If the results had stood, favored come-back HOTYs would have won 14 (74%) out of 19 starts and returned $36.80 for $38.
