PONTE VEDRA BEACH, Fla. (AP) — Webb Simpson navigated his way through a few mistakes but not too much stress to win The Players Championship. Staked to a seven-shot lead, no one got closer than four shots of Simpson, even after a double bogey on the 18th hole when his only concern was finishing the hole. Tiger Woods made another big run that revved up the crowd but had a watery-mishap on the treacherous 17th, an island par-3.
