Mickelson had huge gambling losses

Federal auditors investigating Phil Mickelson's role in an insider trading scheme found his gambling losses totaled more than $40 million from 2010 to 2014, according to an excerpt from Alan Shipnuck's forthcoming biography.

Shipnuck posted the excerpt on his “Firepit Collective” site Thursday. His unauthorized biography on Mickelson is to be released May 17 during the PGA Championship. Mickelson is the defending champion. He has not said if he will be playing.

Mickelson has been out of public view since the final round of the Saudi International

on Feb. 6. A short time later, Shipnuck posted explosive comments from Mickelson on his involvement in Greg Norman's Saudi-backed golf venture.

Mickelson dismissed Saudi Arabia's human rights record, including the killing of Washington Post reporter Jamal Khashoggi, by saying it was worth getting involved with the Saudis if it meant gaining leverage to get what he wanted from the PGA Tour. DAY LEADS WELLS FARGO >> Jason Day shot a 7-under 63 to take the first-round lead at the Wells Fargo Championship. Joel Dahmen was a shot back on what could be the best day for scoring at TPC Potomac at Avenel Farm, with rain, wind and unseasonably cool temperatures in the forecast through Sunday.

Day made five of his eight birdies from inside 10 feet. The Australian took the lead with a chip-in on the par-4 15th hole.

Matthew Wolff, local favorite Denny McCarthy and PGA Tour rookies Aaron Rai, Callum Tarren and Paul Barjon were two shots back. Rory McIlroy, the top-ranked player in the field at No. 7, had an up-and-down 67.
