Vijay Singh is a fan of Warwick Hills Golf & Country Club, the site of three of his 34 PGA Tour victories.

So it comes as no surprise that Singh has committed to playing in the inaugural Ally Challenge in Grand Blanc, tournament organizers announced Thursday.

Singh won the now-defunct Buick Open three times, in 1997, 2004 and 2005. He's one of only two players who won the tournament in back-to-back years, along with Tony Lema (1964-65). 

Singh, who still is occasionally competitive on the PGA Tour and is a three-time major champion (Masters, two PGA Championships), will be joined at the Champions Tour stop by Tom Lehman and Colin Montgomerie. Lehman also has a major to his credit, the British Open. Montgomerie won one of his three senior majors, the Senior PGA Championship, at Harbor Shores in west Michigan in 2014.

The trio has combined for 20 victories on the 50-and-older Champions Tour circuit.

The Ally Challenge is Sept. 14-16, and also will feature previous commitments Bernhard Langer, John Daly, Mark O'Meara, Fred Couples, Kenny Perry, Jerry Kelly and Scott McCarron, as well as Lake Orion's Tom Gillis, a Champions Tour rookie who has received a sponsor's exemption.

Tournament officials also announced Thursday that clubhouse passes are nearly sold out. Limited quantities remain, available at

There will be practice rounds Sept. 11 and 12, and a pro-am tournament Sept. 13.
