As far as Breeders Cup prep weekends go, this is it. This is the big one.

There will be at least 11 events at three different tracks that will impact the upcoming World Championships, one way or another.

Everybody thought tomorrow was the big day, with four Grade 1s at Belmont Park alone, including the Jockey Club Gold Cup that features protem Classic favorite Lawyer Ron.

But check this out.

The Kentucky Cup Day program at Turfway Park is for those wishing to prep on Polytrack while staying away from the glaring lights of either coast.

The showpiece of the five-stakes program, of course, is the G2 Kentucky Cup Classic, matching the Kentucky Derby exacta of Street Sense and Hard Spun.

Enough said.

The Ky. Cup Juvenile Fillies is seeking a viable challenger for next months crowning event at Monmouth Park. Sky Mom, via Saratoga and Steve Asmussen; Bassinet winner and runner-up, Kadira and Dreabons Legacy, respectively, and Dale Romans Love Buzz, will all get serious consideration from the crowd.

A gate-load of three-year-old sprinters will be seeking their identity in the Ky. Cup Sprint, as will two-year-old colts in the G3 Ky. Cup Juvenile. Pulaski Runner, from Bob Holthus, seems a bit more advanced than the rest.

The Ky. Cup Distaff is the most interesting, Derby colts notwithstanding. The most intriguing of them is late developing Pleasant Hill, a winner of the Gardenia at Ellis Park last out and working bullets ever since for Greg Foley.

There are three Grade 1s at Oak Tree, where it appears that Cushion Track once again has proven to be superior to Polytrack early on in terms of bias and race shape: It has played more like legit dirt.

The first things that jump out at Santa Anita are bookend events. Belmonts Flower Bowl vs. Santa Anitas Yellow Ribbon; both Grade 1; both 10 furlongs; Belmont Parks Wait a While vs. Oak Trees Citronnade.

Could make for a nice collision course in four weeks.

The G1 Goodwood will be Swaps winner Tiagos first go against elders after having been reserved from the Pacific Classic. Hell meet legendary Lava Man attempting to rebound from a poly-hating Pac Classic.

The G1 Oak Leaf for juvenile fillies has a deep cast: Set Play the most accomplished; The Golden Noodle most interesting for carrying Jack Van Berg back into the national spotlight.

In addition to Wait a Whiles 10 furlongs in the Flower Bowl, the Pilgrim for juvenile turf horses is interesting in that Todd Pletcher is shifting to grass with The Leopard, most recently a huge disappointment in the Futurity.

As usual the Kelso Mile is a beauty, even if still a G2 event. Multiple G1 winner After Market ships in from California turning back in distance; Bobby Frankel will saddle the very interesting Art Master, while a resurgent Angel Penna Jr. brings late developing English Colony to the fray, a winner of four of five lifetime.

Wait until you see tomorrow's lineup.
