Jay Haas atop leaderboard in Iowa

[truebluefan]

Only Jay Haas knows what it's like to take the biggest lead in Principal Charity Classic history into the final round.

Haas handled the pressure of an equally large cushion just fine five years ago, so the odds for an unprecedented third Champions Tour title in Iowa are certainly in his favor.

Haas will carry a three-shot lead into the final round at Glen Oaks Country Club after shooting a bogey-free 6-under 65 on Saturday.
