Phil Mickelson hasn't played a domestic PGA Tour event in the fall since the FedEx Cup began in 2007.
He was on the Ryder Cup Task Force that came up with a new points formula, and the fall events were left out because Mickelson said it would be giving "the bottom half of the tour'' a head start.
He will be joining them in October.
The Safeway Open, the first event of the 2016-17 season, announced Tuesday that Mickelson will play at Silverado Resort in Napa, California, on Oct. 13-16. It will be the first time Mickelson plays a PGA Tour event in America since 2005 in Las Vegas.
The Safeway Open is in its first year as title sponsor, replacing Frys.com.
"When we made the decision to be the title sponsor of the Safeway Open, Phil is one of the players we hoped would play and support our new event,'' said Bob Miller, chairman and CEO of Albertsons Companies, the parent company of Safeway.
Mickelson referred to Miller and the grocery company as "one of our best PGA Tour sponsors for over 25 years.''
"Amy and I love going to Napa and now we have an even better reason to spend a week with the players and their wives,'' he said.
The Safeway Open is run by the golf event management division of Lagardere Sports and Entertainment, which also manages Mickelson.
