ARLINGTON HEIGHTS, Ill. - Coming out of a third-place finish in the Grade 1 Secretariat and into a third-level turf allowance, Extra Check figured to be settling into a winning spot. But Extra Check may only be the second most talented 3-year-old turf horse in Arlington's Friday feature. Trainer Paul McGee entered Honor in War, a powerful five-length winner of a comeback race here Aug. 11, in Friday's one-mile race, which also showcases the grass debut of the unbeaten Illinois-bred Boom City.
