Back playing in the Masters after a career-threatening car crash, Tiger Woods said he thought he could win a sixth green jacket and on Thursday made a few more believers after carding a solid opening 71.

In his first competitive round of golf in 508 days, Woods mixed three birdies with two bogeys at Augusta National to sit in a tie for 10th four back of South Korea's Im Sung-jae, who is alone atop the leaderboard after posting a five-under 67 highlighted by an eagle at the par-five 13th.

Australian Cameron Smith, who in March won golf's unofficial fifth major, the Players Championship, lurks one back at four-under 68.
