Spain's Gonzalo Fernandez-Castano won the BMW Masters by a single stroke over Italy's Francesco Molinari and Thailand's Thongchai Jaidee after finishing 11-under par on Sunday.

Meanwhile, Rory McIlroy had another roller-coaster day.

Fernandez-Castano, lying second overnight at 7-under and playing in the final group, looked to have sealed his victory in spectacular style by chipping in for birdie at the 17th hole to open up a three-shot lead at 13-under par.
