Schwartzel improves lead in Thailand

Charl Schwartzel increased his lead to four strokes at the Thailand Golf Championship with another 7-under 65 in the second round Friday.

Schwartzel, the 2001 Masters champion, finished at 14-under 130.

Play at the Amata Spring Country Club was delayed due to bad light, but not before Daniel Chopra moved into second place with his second straight 67, one stroke ahead of Masanori Kobayashi (67).

Japanese star Ryo Ishikawa (66) moved up the leaderboard into fourth, two strokes ahead of 2012 Masters champion Bubba Watson (70), Sergio Garcia (69) and Scott Hend (68).
