Millionaires Musketier and Rahystrada, with a combined 11 graded/group victories between them, head a field of seven turf marathoners entered for Thursday's 18th running of the Grade 3, $100,000 Sycamore going 1 1/2 miles on the Keeneland grass.

Trained by Roger Attfield, the 10-year-old Musketier has won six graded stakes at the Sycamore distance, two of them coming in the Grade 2 Elkhorn over the course and three in the Grade 3 Singspiel at Woodbine. The gray son of Acatenango followed up his latest Singspiel win with a second in the Grade 3 Stars and Stripes at Arlington Park, but was unable to factor last out when a well-beaten sixth in the Grade 1 Northern Dancer Turf back at Woodbine.

John Velazquez was aboard for that effort and retains the mount on Musketier for the Sycamore.

Corey Lanerie was in Rahystrada's saddle for only the third time in the Kentucky Turf Cup, and keeps the call on the Byron Hughes pupil for Thursday's contest.

The main threat to the two veterans is Ioya Bigtime, who is two-for-two at the 1 1/2-mile distance. Trained by Chris Block, Ioya Bigtime held off Rahystrada in the Kentucky Turf Cup in his most recent start, and in his initial 1 1/2-mile try defeated Musketier in the Stars and Stripes in July.

Sandwiched in between those two starts, the Dynaformer five-year-old posted a nice runner-up effort in the inaugural running of the American St. Leger. Regular rider Jeffrey Sanchez will be in the pilot's seat for the Sycamore.

Another with a chance in the Sycamore is stakes scorer Kindergarden Kid, who was just a half-length back of Ioya Bigtime and a head behind Rahystrada in the Kentucky Turf Cup. The five-year-old gelding was making his first start for new trainer Mike Maker in that spot after being claimed off Barclay Tagg.
