Led by the sprinter C Z Rocket, California trainer Peter Miller plans to have four runners in three Breeders’ Cup races at Keeneland on Nov. 6-7.

C Z Rocket will be pre-entered in the BC Sprint and BC Dirt Mile, both on Nov. 7, with the BC Sprint as the 6-year-old gelding’s first preference, Miller said Sunday.

C Z Rocket won the Grade 2 Pat O’Brien Stakes at seven furlongs at Del Mar on Aug. 29 to earn a fees-paid berth in the Dirt Mile, and won the Grade 2 Santa Anita Sprint Championship at six furlongs on Sept. 27 to earn a fees-paid berth in the BC Sprint.

ARCADIA, Calif. – As the Breeders’ Cup draws near and prospects are put through drills designed to have them ready for the championship event, some thrive and go forward, while others show they’re not quite ready for prime time. On Sunday, the day before pre-entries were due for this year’s event, both Improbable and Maximum Security showed they are progressing ideally toward a rematch in the BC Classic at Keeneland on Nov. 7, while others based at Santa Anita bowed out.

ARCADIA, Calif. - Flagstaff, the winner of two stakes for sprinters in the last year, will miss the Breeders’ Cup Sprint at Keeneland on Nov. 7 after a recent training setback, trainer John Sadler said Sunday.

“He’s not going to go,” Sadler said. “It’s nothing serious.”

Sadler said Flagstaff will be pointed to stakes at the Santa Anita winter-spring meeting, which begins Dec. 26.

ELMONT, N.Y. - Civil Union, the Grade 1 Flower Bowl winner, worked a solid five furlongs in 1:00.86 over the Belmont turf course Sunday morning in advance of a start in the Breeders’ Cup Filly and Mare Turf at Keeneland on Nov. 7.

Civil Union was inside of Hungry Kitten and, despite going a sharp opening quarter in 23.75 seconds, she maintained a quick, steady pace while appearing to go easily through the stretch.

“She’s been training unbelievable since the race and today I thought she went great,” trainer Shug McGaughey said.

ELMONT, N.Y. - After missing a workout last weekend, Complexity put himself back in the mix for the $1 million Breeders’ Cup Dirt Mile by working a half-mile in 48.85 seconds Sunday morning over the Belmont Park main track.

In his first work since winning the Grade 3 Kelso Handicap on Oct. 3, Complexity went his first quarter in 25.39 seconds, came home in 23.46 and galloped out five furlongs in 1:01.70.

Two winners of Triple Crown races worked Saturday morning for upcoming Breeders’ Cup races, perhaps even a rematch of their epic match in the Preakness Stakes earlier this month.

Authentic, the Kentucky Derby winner, and Swiss Skydiver, the filly who beat males – including Authentic – in the Preakness, both turned in their penultimate drills in preparation for starts on Nov. 7 at Keeneland.

Leading Breeders’ Cup Mile hope Mo Forza is out of the race with what trainer Peter Miller termed a “minor issue.”

Mo Forza was out of action between January and August but roared back into racing with decisive victories in the Del Mar Mile and on Oct. 2 in the City of Hope Mile. But Mo Forza had not posted a timed workout since his last race and Miller had to pull the plug on hopes for making the BC Mile.

ELMONT, N.Y. -  After getting beat as the 3-5 favorite in the Woodward and Jockey Club Gold Cup - both Grade 1 stakes at 1 1/4 miles - Tacitus will head to the $6 million Breeders’ Cup Classic on Nov. 7 as most likely a double-digit priced longshot. Still, Bill Mott doesn’t see the point in leaving a healthy, sound horse who has finished in the top three in 10 career stakes in the barn.

ELMONT, N.Y. – Oleksandra, on a bit of a condensed schedule to make the Breeders’ Cup Turf Sprint on Nov. 7, worked five furlongs in 1:00.98 on Friday morning over the Belmont Park main track. It was her fifth work in 21 days.

Under jockey Joel Rosario, Oleksandra started about two lengths behind a stablemate, joined him in upper stretch and finished on even terms through a final quarter of 23.76.

“She went very well,” trainer Neil Drysdale said. “It’s a bit of a tall order, but right now she’s progressing well.”

ELMONT, N.Y. – Happy Saver, the undefeated winner of the Grade 1 Jockey Club Gold Cup, will not be pointed to the $6 million Breeders’ Cup Classic on Nov. 7 and his connections instead will focus on a 2021 campaign, trainer Todd Pletcher said Friday.

Pletcher said a decision would be made next week whether to give Happy Saver a break or point to the $3 million Pegasus at Gulfstream Park on Jan. 23, with a potential prep in the $100,000 Harlan’s Holiday at Gulfstream on Dec. 12.
