The 5th running of the Grade III $300,000 American St. Leger drew a field of 11 for the marathon race to kick off a $200,000 guaranteed all graded-stakes Festival Pick-4 on Aug. 13 at Arlington International Racecourse. Headlining the 1 11/16-miles turf contest will be Grade II winner Da Big Hoss. Claimed by trainer Mike Maker for owners Skychai Racing last June for $50,000, the 5-year-old son of Lemon Drop Kid has since won five stakes races when stretching out beyond 1¼ miles, including three graded stakes wins. The winner of the Grade II Elkhorn Stakes at Keeneland earlier this year, he is coming off a 1½-length win in the two-mile Belmont Gold Cup in June. Florent Geroux retains the mount and will break from gate five.
