Six-time major winner Phil Mickelson has withdrawn from next week's PGA Championship at Aronimink, citing a personal health matter within his family, the tournament announced on Tuesday.
The 55-year-old left-hander will be replaced in the field by fellow American Max Homa, who had been the first alternate in line for the year's second major tournament.
Mickelson also missed last month's Masters over a personal family health matter. He also had missed the first two events of the LIV Golf season.
Mickelson won the Masters in 2004, 2006 and 2010 as well as capturing the 2013 British Open and taking the PGA Championship in 2005 and 2021, becoming the oldest men's major winner at age 50 when he took the title at Kiawah Island five years ago.
He has been unable to win the US Open to complete a career Grand Slam, finishing as runner-up in the event a record six times, most recently in 2013.
