In 2011, Woods' performance continued to suffer; this took its toll on his ranking. After falling to No. 7 in March, he rebounded to No. 5 with a strong showing at the 2011 Masters, where he tied for fourth place. Due to leg injuries incurred at the Masters, he missed several summer stops on the PGA Tour. In July, he fired his longtime caddy Steve Williams (who was shocked by the dismissal), and replaced him on an interim basis with friend Bryon Bell until he hired Joe LaCava. After returning to tournament play in August, Woods continued to falter, and his ranking gradually fell to a low of #58. He rose to No. 50 in mid-November after a third-place finish at the Emirates Australian Open, and broke his winless streak with a victory at December's Chevron World Challenge.
