Harrington vaults into lead at Charles Schwab Cup

Padraig Harrington shot a scorching 9-under-par 62 on Saturday to take the lead by five strokes at the Charles Schwab Cup Championship in Phoenix.

Harrington sits at 21-under 192 after opening with an eagle and carding seven birdies with no bogeys to cruise past New Zealand's Steven Alker, whose third-round 68 seemed rather pedestrian.

Harrington's 54-hole score also marks the lowest by any player this season on the senior circuit. Even so, Harrington said he's taking nothing for granted in Sunday's final round.

You know, five ahead, so hopefully I'll go out there and play well and can wave at the crowds which if it doesn't happen that way, well, we'll have to dig deep and find another way of winning."

Alker is his closest contender at 16 under, five strokes back. He posted a clean card but with just three birdies.

"(Harrington) had a nice round, just kind of pulled away on the back nine, "Alker said. "I was just trying to make a few birdies coming in. I
