After a third day at the Deutsche Bank Championship in Norton, Massachusetts the competitive field of golf's best continues to ebb and flow.

After an outstanding 10 under par on Day 1, Canadian Mike Weir has reclaimed first spot with a round of four under Sunday and now sits atop the pack at 17 below.

Day 2 leader Tim Clark fumbled his one stroke lead after Saturday with a painful round of two over on the day dropping him all the way into a tie for eighth.

Both Camilo Villegas and Ben Crane enjoyed rounds of eight under to propel themselves up the standings to second and fifth place respectively.

With such an up and down tournament so far it's hard to predict with any accuracy what should unfold in Round 4, but consider both Vijay Singh and Sergio Garcia threats for the title as their tournament totals of 14 under have them in a tie for third just three strokes behind Weir.
