Battle lines drawn again as big two fight it out

Having spent more time with one another in the last week than most married couples, the good news is Tiger Woods and Pádraig Harrington were still talking with one another after a four-and-a-half hour walk.

Even more, they were laughing.

Then again, why not? Grouped together in Game 23, they had combined for 10 birdies against just one bogey, which is not a bad way to start any tournament, let alone a major. Their brilliant work had not only left them at five-under 67 (Woods) and four-under (Harrington), but propped 1-2 atop the leaderboard of the 91st PGA Championship with half the field having completed play at Hazeltine National GC.
