It was a routine morning on a mild but cloudy Wednesday morning at Churchill Downs with the majority of Kentucky Derby and Oaks entrants putting in routine gallops.

Japanese hopefuls Luxor Café and Admire Daytona (JPN) had walk days a morning after working five furlongs in 1:02.40 and Coal Battle also walked.

As was the case last weekend when trainers were watching the weather before putting final works into their charges, rain may be a factor this weekend in Louisville.

Thunderstorms were in the forecast for Wednesday as well as showers and thunderstorms the next three days.

One horse whose connections seem unbothered by the possibility of rain is Burnham Square.

Whitham Thoroughbreds’ Burnham Square galloped a mile and a half during the 7:15-7:30 window under Mark Cutler for trainer Ian Wilkes.

Winner of the Blue Grass Stakes (GI), Burnham Square has not raced on an “off” track, something he could possibly encounter Saturday.

“He worked really good over it Saturday,” jockey Brian Hernandez Jr. said of Burnham Square, who drilled five furlongs in :59.40 over a track labeled as good. “Good horses can overcome a lot.”

Cutler, who was the exercise rider for 2007 Kentucky Derby winner Street Sense, does not feel an off track would be a problem for Burnham Square.

“But Street Sense. No, no, no,” Cutler said with a laugh. “If it was raining, he didn’t even want to come out of the barn. I knew we were in trouble when it was sloppy for the (Breeders’ Cup) Classic at Monmouth when he was fourth.”
