ARCADIA, Calif. — Royal Delta led all the way in winning the $2 million Ladies’ Classic by 1½ lengths Friday at Santa Anita, making the defending champion the only favorite to win on an upset-filled opening day of the Breeders’ Cup.
Jockey Mike Smith earned his 16th victory in the event’s 29-year history, breaking a tie for most wins with fellow Hall of Famer Jerry Bailey.
‘‘I hope to be around a few more years to add to it,’’ the 47-year-old rider said.
Royal Delta gave Hall of Fame trainer Bill Mott his second consecutive win and fifth overall in the Ladies’ Classic, putting him in position to sweep the weekend’s biggest races, a feat he accomplished last year. He has three runners in the $5 million Classic on Saturday, a race he won last year with Drosselmeyer.
‘‘We’re certainly not counting our chickens before they hatch,’’ Mott said. ‘‘I think any one of the three has a chance.’’
Royal Delta was the 8-5 favorite in the field of eight fillies and mares, considered one of the deepest fields among the 15 races during the world championships. She ran 1⅛ miles in 1 minute 48.80 seconds and paid $5.40, $3.60, and $2.60. She won by 2½ lengths last year with Jose Lezcano aboard.
This time, Royal Delta took charge early, making her way to the lead on a brisk pace. Turning for home, it appeared My Miss Aurelia and Include Me Out were going to overtake Royal Delta, but Smith applied a left-handed whip and she dug in gamely to hold off the challenge.
‘‘She’s just brilliant, she really is,’’ Smith said. ‘‘I was always taught when you’re on a talented horse stay out of their way. I felt confident all the way around there.’’
My Miss Aurelia returned $5.80 and $4, losing for the first time in seven career races.
‘‘I hate that she didn’t win, but I just love this filly,’’ trainer Steve Asmussen said. ‘‘She never blinks.’’
Include Me Out was another 1¼ lengths back in third and paid $5.20 to show.
Awesome Feather, the 2-1 second choice, came in undefeated in 10 races but finished sixth.
Questing was eased down the backstretch, but the on-call veterinarian said there was no apparent injury to the 3-year-old filly.
Royal Delta caused Mott some worry Monday when she arrived from New York with a gash on her right hip that required stitches. She was injured loading on a flight that left in the early morning hours to beat Superstorm Sandy.
‘‘Whew, I can tell you I feel a whole lot better right now,’’ Mott said. ‘‘It’s a real sigh of relief and a big joy to watch her run.’’
Six different jockeys, trainers, and owners won each of the Breeders’ Cup races in front of 34,619 fans on a sunny day.
The biggest upset was Calidoscopio’s 4¼-length victory in the $500,000 Marathon, jockey Aaron Gryder’s first Breeders’ Cup win. The 17-1 shot from Argentina paid $36.40 to win and at 9 became the oldest Breeders’ Cup champion.
Age also played a part in the second-biggest upset. Sent off at 15-1 odds, Hightail kicked off the two-day championships with a nose victory in the $500,000 Juvenile Sprint, giving Hall of Fame trainer D. Wayne Lukas his leading 19th Breeders’ Cup victory at 77.
In the $1 million Juvenile Fillies Turf, 11-1 shot Flotilla rallied to win by 1¼ lengths and paid $24.80. Trainer Mikel Delzangles and jockey Christophe Lemaire, both from France, won their first Breeders’ Cup race.
Zagora won the $2 million Filly & Mare Turf by three-quarters of a length at 9-1 odds. She paid $20.40 to win under Javier Castellano for owner Martin Schwartz, who made his fortune trading on Wall Street.
Beholder led all the way to win the $2 million Juvenile Fillies, holding off 3-2 favorite Executiveprivilege by a length.
