NEW YORK (Reuters) - Leylah Fernandez may not feel the weight of expectation as she heads into the U.S. Open final but the Canadian teenager will have a chip on her shoulder put there by those who doubted her.

Dropped from Tennis Quebec's development program when she was seven-years-old and told by teachers to forget becoming a professional and focus on school, Fernandez will have the last laugh on Saturday when faces fellow teen Emma Raducanu for a first Grand Slam title and a winner's purse of $2.5 million.
