Late afternoon rain at Laurel Park has resulted in races 9 and 10 being moved to the main track.
Race 10, originally carded at 1 1/16 miles, will now be a one-turn mile.
Races 9 and 10 are the last two races on the card. They will be considered All-win races in the late pick four, and pick five. Wagers in the Rainbow 6will be refunded.
The main track is "good" and has been sealed for race 8, the $75,000 Polynesian, a seven-furlong sprint.
