Since Tiger's last major win, 16 majors have been played, but Tiger has only started in 12 of them. So technically, he's only gone 12 major starts without winning. He's missed a full year's worth of majors since his last win due to injury. 12 starts isn't that much longer than the 10 he went between April '97-August '99 or the 10 between June '02-April '05.
