World Cup debutants Curacao have parted company with head coach Fred Rutten just one month before the tournament kicks off, the federation confirmed.

Top-ranked defending champion Scottie Scheffler and a host of world-class rivals took their first practice rounds on Monday at Aronimink ahead of the 108th PGA Championship, which tees off Thursday.

The 31-year-old made her decision public in an emotional video posted on the club's official website.
