Brave Anna and Roly Poly gave Irish trainer Aidan O’Brien a sweep of the exacta in Saturday’s $234,000 Cheveley Park Stakes for 2-year-old fillies at Newmarket, England, at the expense of the previously unbeaten Lady Aurelia, who finished third.

Tepin, Tepin, Tepin. And still more Tepin. You cannot talk about North American turf racing at the moment without the remarkable mare’s name coming up.

Tepin won the 2015 Breeders’ Cup Mile, and with nothing but wins on her form again this year, including an historic excursion to England, where she won the Group 1 Queen Anne Stakes in June, Tepin remains the leader of the BC Mile division as summer turns to autumn.

Plenty of Bill Mott-trained 2-year-olds begin their career racing a mile or longer on turf. Mott has sent out 86 such starters in the last five years. Only four of them won.

Mott entered the Hall of Fame 18 years ago at age 45. There’s a decent chance he knows his way around a young horse. If Mott is winning at 5 percent in a category, it’s because winning isn’t the primary goal for those horses. A first start is a means to an end, a time to learn and practice.

Of the previous eight Breeders’ Cup events held at Santa Anita, six winners of the $2 million Juvenile were based in Southern California. Only head losses by He’s Had Enough (2012) and Lookin At Lucky (2009) have kept it from being a clean sweep for West Coast-based runners in the Juvenile.

Surprisingly, there have been some very nice prices among those winners, including Texas Red (13-1 in 2014), New Year’s Day (10-1 in 2013), and Action This Day (26-1 in 2003).

Three of the last four runnings of the Breeders’ Cup Filly and Mare Turf have been won by horses trained by Chad Brown, with Zagora scoring in 2012, Dayatthespa in 2014, and Stephanie’s Kitten in 2015.

Roughly six weeks away from the 2016 renewal, to be run Nov. 5 at Santa Anita, Brown has an opportunity to keep his winning ways going with three talented prospects being pointed to the race in Lady Eli, Dacita, and Sea Calisi. All three rank among the best turf mares in North America.

With the Breeders’ Cup returning yet again to California this fall, the state’s favorite son is the parasol-shaped straw that stirs the frothy drink.

California Chrome, currently ranked as the best horse in the world, is the acknowledged favorite for the $6 million Breeders’ Cup Classic at Santa Anita on Nov. 5, and his dominating victories this year – from Santa Anita to Meydan to Del Mar – have caused the connections of several of his potential rivals to adjust their prep plans, or their Breeders’ Cup plans themselves.

One of the central questions leading into this year’s Breeders’ Cup at Santa Anita is whether Frosted will go in the $1 million Dirt Mile on Nov. 4 or the $6 million Classic on Nov. 5. He has earned berths in both races, but a decision is pending, according to trainer Kiaran McLaughlin.

“We’re going to the Breeders’ Cup – the Classic or the Dirt Mile,” McLaughlin said Monday.

Unlike a year ago, when Songbird was beginning to exert her dominance in the 2-year-old filly division, this season’s Breeders’ Cup Juvenile Fillies is wide open with six weeks remaining before the race.

The $2 million Juvenile Fillies will be run at Santa Anita on Nov. 5. Currently, Union Strike, who used a strong late run to upset the Del Mar Debutante at 7-1, is the leading West Coast contender for the 1 1/16-mile race. Sweet Loretta and Pretty City Dancer, who dead-heated for first in the Spinaway, and Adirondack winner Nonna Mela look best in the East.

The leading candidate for the $1 million Breeders’ Cup Juvenile Fillies Turf at Santa Anita on Nov. 4 is a Kentucky-based filly who has yet to run in a stakes in the United States.

After winning a maiden race at Keeneland, Lady Aurelia won group stakes at Royal Ascot in England in June and at Deauville in France in August. Trained by Wesley Ward, Lady Aurelia will be favored to win Saturday’s Group 1 Cheveley Park Stakes at six furlongs on turf at Newmarket in England.

With 2015 Breeders’ Cup Sprint winner Runhappy being pointed toward the Dirt Mile and 2015 Sprint runner-up Private Zone on the shelf for the remainder of the season, this year’s BC Sprint figures to be a wide-open affair, with the field not likely to be set until the last of the six BC Challenge races in the division is decided Oct. 8.
