Rory McIlroy, Shane Lowry and Seamus Power are among the players in the field for the WM Phoenix Open this week.
The tournament, which takes place in Arizona, is known for its rowdy atmosphere, although there were some incidents with spectators that marred last year’s event.
A hole-in-one from Sam Ryder on the par-three 16th prompted many of the 20,000 spectators in the grandstand to throw their beer cans on to the green, causing a 10-minute delay in play.
