Tiger Woods: Golf star sketches out his future -- more rehab and focus on 'big events'

He was walking onto the famous 18th green hours before the Masters leaders, but Tiger Woods still received an emotional standing ovation from the patrons.

A grueling four days had taken its toll on the golfing great, on a body which hadn't played competitive golf in almost 17 months and which still wasn't fully recovered from serious injuries following a car crash.

Appearing to be walking with a slight limp -- one which became more pronounced as the 72 holes progressed over Augusta National's hilly terrain -- Woods's face gave the impression it had been an enormous physical challenge getting round the course.
