Arlington: One race off turf, last four on


Race 6 is off turf. The rest of the day's turf races -- two stakes, and an all-grass late pick 4 -- still is on. The going should be quite testing.

Superstardom the only horse out of the American 1000 Guineas. Call Shot and Prairie Breeze have been scratched from the Arlington Classic.
