ARCADIA, Calif. – There was a definite chill in the air Wednesday morning at Santa Anita, where the temperature struggled to get out of the 40s for much of the morning. But the unseasonably cold weather was tempered some by all the action heating up on the racetrack, with the majority of this year’s Breeders’ Cup contingent out to train over all three surfaces, including the turf course, which saw its first major flurry of activity Wednesday morning.
