Tiger Woods endured a difficult return as he shot a four-over 75 in the first of the PGA Tour’s play-off events at Liberty National in New Jersey.
Woods was playing his first round since missing the cut in The Open last month.
He recorded five bogeys and one double bogey to lie 13 strokes behind early leader Troy Merritt, who fired a 62.
Northern Ireland’s Rory McIlroy was three shots off the lead after a six-under 65 with England’s Danny Willett a further shot back.
Scotland’s Russell Knox also finished on five-under alongside 2018 Masters champion Patrick Reed.
