For bettors, Friday proved to be a massive day for potential profit, as scintillating underdogs overtook their favored counterparts through much of the first slate of races at the 2012 Breeders' Cup.
Of the six races that took place on Friday, Royal Delta wound up being the only morning-line favorite to take victory, doing so in the Ladies' Classic.
Outside of Delta, Beholder was the only other horse to hit below the $10 mark in payouts, as the upsets started early with massive underdogs taking the first few races.
That means big money was to be had in the first day of the 2012 Breeders' Cup, but only if you had the right ticket.
Which horses came up the biggest for their bettors? Here's a look at the biggest payouts from all of Friday's action at Santa Anita:

Flotilla ($24.80, Juvenile Fillies Turf)
The entire Juvenile Fillies Turf field came into Friday's race as massive underdogs, as Sky Lantern looked to be an unstoppable juggernaut.
That proved not to be the case, however, as the morning-line favorite did not contend, finishing eighth for the first non-money finish of her career.
Without Sky Lantern holding everyone back, the race became wide-open and Flotilla took advantage, lurking in the back before making a fantastic charge to the front.
The win was the 2-year-old filly's first, and came in just the third race of her flourishing career. French-bred and trained by Mikel Delzangles, Flotilla took advantage of Santa Anita's fast track and proved far more formidable than anyone could have imagined.
Hightail ($32.80, Juvenile Sprint)
Starting off the weekend's festivities with a bang, Hightail shocked the Juvenile Sprint field and captured the first race of his young career.
The victory gave legendary trainer D. Wayne Lukas his 17th Breeders' Cup victory, which gives him far and away the most in the event's history. Racing against fellow 2-year-olds, Hightail came in relatively un-touted, but had just four other horses standing in his way after pre-race dropouts lowered the field to five.
Nonetheless, Hightail didn't make it easy on anyone. He sat fourth for most of the race before seemingly being shot out of a rocket down the stretch to beat Merit Man by the slightest margin.
Calidoscopio ($36.40, Marathon)
The second race of the afternoon continued a string of non-favorites winning, as Calidoscopio came back with a brilliant stretch run to overtake Grassy and Atigun for the victory.
The 9-year-old horse became the oldest ever to win a Breeders' Cup race and overcame a slow start to win by 4.5 lengths. Trained by Guillermo J. Frenkel-Santillan, Calidoscopio came in as a 17/1 underdog, which ranked ninth among the 13 horses entered in the second race of the day.
This win serves as the Argentinian-bred horse's second consecutive win and third of 2012, after having a combined two wins in 2010 and 2011.
