THE WOODLANDS, Texas (AP) Bernhard Langer shot a 4-under 68 on Saturday to open a three-stroke lead in the Champions Tour's Insperity Invitational.
Langer had a 10-under 134 total at The Woodlands Country Club.
The 56-year-old German player won the 2007 event at Augusta Pines and successfully defended his title in 2008 at The Woodlands. He won the season-opening event in Hawaii for his 19th Champions Tour title.
Colin Montgomerie was second after a 66, the best round of the day.
Defending champion Esteban Toledo, Gary Hallberg and Bart Bryant were four strokes back. Hallberg had a 67, Toledo shot 71, and Bryant - tied for the first-round lead with Langer - had a 72.
