DUBLIN, Ohio — It was a strange day of rises, falls and departures at the Memorial Tournament.

Phil Mickelson played 18 holes, said he was tired and withdrew. Four-time winner Tiger Woods was in his accustomed spot near the top of the leaderboard despite a double-bogey, while Rory McIlroy weathered an embarrassing quadruple-bogey.

And the best rounds of the day at the star-studded tournament — featuring seven of the top 10 players in the world — were put up by Scott Stallings, Erik Compton and Spencer Levin, who have a grand total of one PGA Tour win.

The biggest news was that Mickelson shot a 79 and then told playing partners Rickie Fowler and Bubba Watson that he was going home because he was mentally drained after a hectic past few weeks that included taking his wife, Amy, to Italy and France for her 40th birthday.
