'Tiger effect' leads to highest PGA Tour ratings in 5 years
PALM HARBOR, FL - MARCH 11: Tiger Woods plays his second shot on the 18th hole during the final round of the Valspar Championship at Innisbrook Resort Copperhead Course on March 11, 2018 in Palm Harbor, Florida.

ORLANDO, Fla. (AP) Tiger Woods was one shot away from a chance to win, and the PGA Tour had its largest television audience in five years.

NBC Sports Group says the final round of the Valspar Championship earned a 5.11 overnight rating, up 190 percent over the previous year and the highest-rated PGA Tour broadcast since Woods won The Players Championship in 2013. That doesn't include the majors.

Woods, returning from a fourth back surgery, was one shot out of the lead going into the final round. He had a 40-foot birdie attempt on the 18th hole to force a playoff with Paul Casey and came up short.

Golf Channel's two-hour window before the NBC telecast Sunday earned a 1.65 rating, its highest-rated coverage for the lead-in window since it began in 2009.
