KUALA LUMPUR - Lee Westwood stayed on track to defend his Malaysian Open title on Friday, topping the leaderboard for a second straight day with a five-under-par 67. The Englishman was in a tie for the halfway lead with Spain's Alejandro Canizares, who shot Friday's lowest round in the field, a bogey-free 65. Westwood's first-round co-leader, Graeme McDowell, tumbled down the board, however, shooting a one-over 73 including three bogeys and a double. That left Graeme six strokes off the pace. But Westwood, who won last year by seven strokes and carded a 66 on day one, posted yet another steady round on a course that seems a perfect match for his game. "I played nicely again and probably only hit one poor shot all day, from the middle of the fairway on the fifth hole," said Westwood.
