Fast, firm, and still over 90 degrees as the 10-race, six-stakes card featuring the Grade 3, $500,000 Indiana Derby card approaches. Working backward re stakes scratches 

Race 9 Indiana Derby - no changes
Race 8 Indiana Oaks - scratch Haynesfest (#2)
Race 7 Warrior Veterans - no changes
Race 6 IN Gen'l Assembly - scratch Dutch Parrot (#2) 
Race 5 Michael G Schaefer - scratch Siem Riep (#4), Nun the Less (#7)
Race 4 Marie Hulman George - scratch Sweet and Wicke (#1)

The most meaningful of these changes is Siem Riep coming out of the Schaefer. That could leave Pioneer Spirit (#3) loose on the lead in a race where Seeking the Soul (#2) figures to be heavily favored. 

Race 3, a two-turn dirt allowance that's the second leg of the early pick four, lost three horses to scratches including 3/1 morning-line favorite Heavy Roller (#4).
