PGA Tour Champions — Paul McGinley is 12 strokes adrift of Germany's Bernhard Langer with a round to play in the Insperity Invitational in Texas.
The Dubliner, 51, double-bogeyed his final hole at The Woodlands, carding a 74 to go into Sunday tied for 59th on three-over 147.
Two-time Masters Tournament winner Langer, 60, added a 72 to his opening 63 to lead by a stroke on nine-under-par from Tom Pernice Jr. (68), Miguel Angel Jiménez (69), Mark Calcavecchia (69) and Scott Dunlap (70).
The winner of 10 senior majors, Langer has won 36 times on the PGA Tour Champions since 2007 but has yet to win this year.
After winning seven events last year, including three majors, he has twice lost in playoffs this season.
