MILWAUKEE -- A steady Ben Crane fired a 1-under 69 in sweltering heat Sunday to win the U.S. Bank Championship in Milwaukee by four strokes over Scott Verplank.

The victory was Crane's second on the PGA TOUR. He finished with a 72-hole total of 20-under 260 and earned a $684,000 check.

Crane's fourth straight round in the 60s included an eagle, two birdies and three bogeys. After he birdied No. 17, the 29-year-old from Oregon had the luxury of a four-stroke advantage as he came to the final hole..

Chad Campbell (65) finished five shots back in third, and two-time winner Jeff Sluman (68) was fourth at 14 under.

Crane, whose lead never dipped below three strokes Sunday, is only the second wire-to-wire winner in Milwaukee, joining Ed Snead, who did it in 1974 at Tuckaway Country Club.

Crane, whose only other PGA TOUR win came at the 2003 BellSouth Classic, is the fourth golfer this year to put his name atop the leaderboard all four rounds of a tournament, joining Phil Mickelson ( AT&T Pebble Beach National Pro-Am ), Justin Leonard ( FedEx St. Jude Classic) and Tiger Woods (British Open).

After enduring a stormy three days that included three rain delays, two course evacuations and a suspension on account of darkness, the golfers slogged through a hot, humid final day at Brown Deer Park, where the heat index hovered around 105 degrees.

The greens were soft and sticky but the winds kept golfers from getting too close to Crane, who didn't seem to mind the soggy course.

His three-day total of 19-under 191 was the best 54-hole start on TOUR this year and just one stroke shy of the tournament record set by Sluman in 2002.

It was Crane's first 54-hole lead on TOUR, and his two-stroke advantage over Verplank quickly doubled when Verplank bogeyed No. 1 and Crane birdied No. 2.

Crane holed out from 19 yards from the first cut of rough on No. 6 for an eagle to go to 21 under, and even though he bogeyed the next hole, he made the turn with a four-shot lead over Verplank, who, like the rest of the field, never mounted a serious charge.

Verplank was hoping to snap his streak of 96 tournaments without a win.

"I just didn't play good enough," said Verplank, whose last win came in the 2001 Bell Canadian Open. "I just never found the rhythm. The wind and the playing conditions made it that way and certain challenges of playing in the last group made it tough, too."
