Kentucky Derby: Pass

Kentucky Derby optics are ever changing. Mage's 15-1 victorySaturday underscored that in ways that might have eroded some of the handicappingbulwark for America's biggest race. It also validated some other bettingoptics.

Whether it was the Final Fractions Theory, which workedagain, or certain speed-figure thresholds, which did not, the outcome of therace might have done more to muddle handicapping for Kentucky Derby 2024 than itdid to clarify it.

Zipse: Mage, Forte have budding new rivalry.

With 362 days until the next one, ask the simple question.Did these handicapping prisms work?

Final Fractions Theory – yes

Mage finished the last three furlongs of the Florida Derby(G1) in 37.8 seconds. He ran the last furlong that day in 13.2 seconds.

The Final Fractions Theory pioneered by journalist andpublicist Jennie Rees discovered that most Derby winners met one of twocriteria in their last 1 1/8-mile prep. They either went the last eighth of amile in no more than 13.0 seconds or the last three-eighths in no more than38.0 seconds.

The key word in that sentence was "or."

Mage qualified with his last three-eighths at GulfstreamPark but not his last eighth. No matter. That was good enough to make him the30th cashable Derby winner in the last 35 years to meet one of those requirements.Cashable, by the way, meant Country House and not Maximum Security in 2019. Italso meant Medina Spirit, not Mandaloun, in 2021.

The downside was the FFT was not a fine sieve this year. Bythe time all the scratches were made, all but one starter qualified under the 13-or-38rule. Cyclone Mischief, the one who did not, came home last.

Beyer and TimeformUS minimums – no

Well, barely. According to Daily Racing Form, Mage'sbest Beyer Speed Figure coming to Churchill Downs was the 94 he got forfinishing second to Forte in the Florida Derby.

That meant 27 of the last 32 cashable winners in theKentucky Derby had a Beyer of at least 95 coming into the race. It also meant threeof the last five did not. Country House came into Louisville in 2019 with a bestBeyer of 91. Rich Strike was no better than an 84 before his victory in 2022.Now there is Mage.

Barely.

The TimeformUS threshold says a Derby winner must have had a115 or higher speed figure in one of his last three preps. Fourteen of the last19 Derby winners had met that expectation before Saturday. Mage's Florida Derbyrating was 114. So make that 14 of 20, because Mage did not hit the number.

Barely.

100 Brisnet Speed Rating – yes

Mage became the 19th cashable Derby winner in the last 24years to have come in with a triple-digit Brisnet rating. He got a 101 in theFlorida Derby.

Can we get another barely?

Rich Strike had nothing better than a 95 last year. MedinaSpirit cashed with only a 98 beforehand in 2021. Country House's best was 95 cominginto 2019. In the context of May renewals of the Derby, Mage got the Bris trendback on track for the first time since 2018.

The barely crop looks bountiful here.

Pacesetter or stalker – yes

His designation might have changed as a result of his winning rallyfrom 16th place Saturday, but Mage went into the Derby with a Quirin SpeedPoints designation of E/P 5. That stands for early-presser or, in more commonparlance, stalker.

Between 2014 and 2021, eight consecutive first-place Derbyhorses had E or E/P designations, meaning early or early-presser types. In otherwords, pacesetter and stalker.

The Quirin trend began to erode, though, when Country Housewas promoted over Maximum Security to cash as the 2019 Derby winner. Being astone-cold closer, Country House had a Quirin designation of S 0.

In 2021, Medina Spirit crossed first with his E 7, but he wouldbe supplanted the following winter when stewards declared Mandaloun, a P 7 mid-packrunner, the new winner.

Rich Strike, an S 0 type closer, blew up the Quirin theorylast year. Even with Mage technically having an E/P 5 designation, the tacticshe displayed in winning the Derby was more in line with the closing style that hascashed three times in the last five years.

Florida Derby and Fountain of Youth – yes

No prep race has produced more Kentucky Derby winners thanthe Florida Derby. Mage became the 25th.

What makes this all the more remarkable is that the America'sbiggest race has been around since 1875. The Florida Derby did not begin until1952. That means it has produced 35 percent of the Kentucky Derby winners inits relatively short history.

Granted, it had been six years since the last one, and Magewas the first Florida Derby also-ran to wear the roses since Go for Gin in1994. But Saturday marked the seventh time in the 21st century that GulfstreamPark's signature race in the spring was a bellwether for the first Saturday inMay.

Mage also ended a drought for the Fountain of Youth (G2),which has produced 14 Kentucky Derby winners but had none since Orb in 2013.Mage was only the second Fountain of Youth finisher to win the Derby since1996.

UAE Derby – same ol’ x 19

"This year will be different."

Every year the UAE Derby (G2) sends a horse or two to the Kentucky Derby. Andevery time there are myopic predictions that this will be the one.

Derma Sotogake, who won the Dubai race in March, finishedsixth Saturday.

There have been 19 horses who have come out of the UAE Derbyto start in the Kentucky Derby. None finished better than fifth.

What is the definition of insanity?

Curse of Apollo – no

Apollo and Justify, right? Mage just joined the list ofDerby winners who did not race at age 2.

Instead of pointing out there were 136 years between Apolloand Justify, how about remembering there have been two such winners in the lastsix runnings of the Derby?

Because horses are being raced to breed rather than being bredto race, this might not be such a rarity anymore.

Winter-book jinx – yes

Churchill Downs stopped updating its list of winter-bookfavorites around the time Las Vegas stopped having only one casino take futuresaction for the Derby.

Picking up where it left off, though, since Spectacular Bidin 1979, only one New Year's Day betting favorite in Nevada has cashed on thefirst Saturday in May. That was Street Sense in 2007.

On Jan. 1, Arabian Knight was 10-1 at Caesars Sportsbook,and Forte was 13-1 at Circa Sports. Neither of those two shortest-priced horseseven made it to the Derby.

In 2021, Corniche was the 6-1 favorite at Caesars at WilliamHill. He not only did not get into the Derby, he did not race again until thatsummer. He got hurt finishing last in the Amsterdam (G2) at Saratoga and wasretired to stud.

Post 17 drought – yes

By the time all the scratches were done, Mandarin Hero gotstuck with the one post position that never has produced a Kentucky Derbywinner.

His 12th-place finish meant that of the 44 horses who havestarted from there, only three have been in-the-money finishers, nonebetter than second-place Forty Niner in 1988.

At least some things about the Kentucky Derby are reliable.History says there is a 99.3 percent chance it will be run for the 150th timenext May 4.

Only 362 days to go.
