This will mark Mickelson's third straight appearance at the San Antonio event, although the last two years the tournament preceded the Masters and had been a part of Mickelson's preparation for the season's first major. He withdrew during the third round in 2014 because of a pulled oblique muscle and finished T-30 last year.
Prior to 2014, Mickelson had not played the event since 1992.
Mickelson is in the midst of a resurgent season that included a runner-up finish at Pebble Beach as well as a T-3 finish in Palm Springs. He had top-20 finishes in five of his last six starts heading into the Masters, but he made an abrupt exit after a second-round 79 that marked his highest-ever competitive score at Augusta National. He remains in search of his first win since the 2013 Open Championship.
Mickelson will be one of the headliners next week at TPC San Antonio, among a field that will also include Dustin Johnson, Patrick Reed, Zach Johnson, Hideki Matsuyama, Brandt Snedeker, Bryson DeChambeau and defending champion Jimmy Walker.
