Lee Westwood was back on top of the leaderboard at the second day of Masters tournament play before he double-bogeyed the 18th and final hole of the day. That puts him behind Rory McIlory, Fred Couples, Sergio Garcia and Jason Dufner, who all share the lead with a 5-under par score.
Dufner is done for the day, and shot 2-under in the second round to set himself up for the contention and four-way tie for the lead. Couples is shooting an impressive 5-under par on the day through 17 holes. Through 16 holes, McIlroy and Garcia are shooting 5-under on the day as well as 5-under on the tournament.
Tiger Woods is minus-one through five holes, while defending champion Charl Schwartzel is one-under through six holes.
