MEMPHIS (AFP) — Two-time major champion Collin Morikawa has pledged to donate $1,000 for every birdie he makes in the US PGA Tour's FedEx Cup playoffs to fire relief efforts in Hawaii.

The American, who has strong family ties to the island of Maui, made the announcement on Instagram on Thursday as the first playoff event, the St. Jude Championship, teed off in Memphis.

"Maui has always held a special place in my heart — my grandfather owned a restaurant called The Morikawa Restaurant, on Front Street in Lahaina," Morikawa, who won the 2020 PGA Championship and the 2021 British Open, wrote.
