Rory McIlroy starts with a birdie as he looks for Valhalla repeat

Rory McIlroy made the ideal start as he looked to put personal turmoil to one side and secure an overdue fifth major title in the 106th US PGA Championship.

Following a 10-minute delay to the start of play due to lingering patches of mist at Valhalla, McIlroy got his campaign under way on the par-five 10th and hit a well-controlled pitch to six feet to set up an opening birdie.

The world number two had understandably refused to talk about his private life in his pre-tournament press conference, which came the day after it emerged he had filed for divorce from his wife of seven years, Erica, on Monday.
