Tiger Woods had his first big test in nearly four months on the golf course, and it had nothing to do with his swing.

It was his legs. He walked 18 holes for the first time since the PGA Championship.

Woods looked to be at ease with his game Wednesday during the pro-am of the Hero World Challenge. The real test starts Thursday against an elite 18-man field at Isleworth Country Club, where Woods spent the first 16 years of his career.

He already got the attention of Steve Stricker, who watched him hit a few balls on the practice range. Stricker said it reminded him of Woods from the early 2000s, an era when Woods was at the top of his game.
