AVONDALE, La. – Lucas Glover increased his lead to two strokes in the Zurich Classic to remain in position for his first victory in two years.

The 2009 U.S. Open winner shot a 2-under 70 on Saturday to reach 14 under at TPC Louisiana.

Kyle Stanley, Jimmy Walker, Billy Horschel and D.A. Points were tied for second. Stanley had a 65, Walker and Horschel shot 66, and Points had a 70.

Guan Tianlang, the 14-year-old Chinese amateur, shot a 77 to drop to 2 over — last among the 71 players who made the cut. He tied for 58th two weeks ago in the Masters after becoming the youngest player to make the cut at Augusta National, and will play in a U.S. Open qualifier in two weeks in Dallas.
