Tiger Woods' historic run to win the U.S. Open golf championship—which culminated in a 19-hole playoff in Torrey Pines, California on Monday—was great theater. And it delivered some record-breaking online traffic, too.

Golf.com [1], part of Sports Illustrated's Golf Group, attracted 1.1 million unique visitors on Monday, more than double the traffic of any single day. The site drew 2.2 million unique visitors during the five-day tournament. (Part of the appeal was something called "The Tiger Tracker" which followed Woods' performance throughout the tournament.)

Publisher Charlie Kammerer says ad revenue was up 67 percent over last year for the site's U.S. Open packages, which include integrated print and online buys.

Sports Illustrated, meanwhile, pushed up [2] the on-sale date of its print magazine [3] by one day to Tuesday—less than 24 hours after the tournament's sudden-death playoff.
