Jorge Fernandez won't attend his daughter Leylah's all-teen US Open final showdown Saturday with Britain's Emma Raducanu over fears about messing with routines that are working.

Fernandez, a former footballer from Ecuador who became a tennis coach for his daughter, will watch from home in Florida as he has for two weeks when 19-year-old Fernandez meets 18-year-old qualifier Raducanu for the title.
