For the third time this season, Love will take the lead into the final round of a PGA Tour event. He failed to produce victory in his previous two attempts.
Love, who led by as many as five strokes coming down the stretch, held on Saturday for a one-shot lead over Scott Hoch in the Advil Western Open.
Love shot a 3-under 69 to finish 54 holes at 14-under-par 202. Hoch birdied his final four holes for a round of 66.
Mark Wiebe (67) and Brandel Chamblee (70) are tied for third place at 10-under. Phil Mickelson is in solo fifth place at 9-under after a solid 67.
Tiger Woods is in a 15-way tie for ninth place at 7-under following an erratic 68.
Rain delayed play for just over two hours on Saturday. It marked the seventh straight week that Mother Nature has intervened in a PGA Tour event.
Once play resumed at 3:15 p.m. local time, Love went on a full-out assault at the Cog Hill Golf & Country Club.
Upon making the turn, he birdied holes 10-12 to take a four-shot lead at 14-under-par. That lead was extended to five when Love chipped in for birdie at the par-5 15th.
Love wasnt as fortunate at the par-4 16th. Short of the green in two, he pitched up to three feet, but missed the par save. He parred his final two holes to finish at minus-14.
Love led by a shot entering the final round of the Buick Invitational, where he and Frank Lickliter lost to Mickelson. Two weeks later, he took a three-shot advantage into the final round of the Nissan Open, where he shot 75 on Sunday to tie for eighth.
Loves lone triumph in 2001 came courtesy of a come-from-behind victory in the AT&T Pebble Beach National Pro-Am.
Mickelson made a late run up the leaderboard by birdieing three of his final four holes, including a 45-foot bomb on the par-4 17th.
Woods played a Mickelson-esque round on Saturday. The 1997 and 99 Western Open champion recorded two eagles, five birdies, one bogey and two double bogeys.
Tiger made a 3 at the par-5 5th, only to make a 5 at the par-3 6th. He stuck his approach shot on the par-4 7th to three feet for birdie, but gave that shot and another back when he three-putted for his second double bogey in three holes at the par-4 8th.
Woods recorded a routine two-putt birdie at the par-5 9th, and made his way to the 11th before play was halted.
When he and the rest of the field returned to the course, Tiger badly sliced his second shot at the par-5 11th near the corporate tents. It took him two more shots to reach the putting surface, where he two-putted for bogey.
However, after verbally chastising himself when he hit his tee shot on the par-3 14th 50 feet from the hole, Woods dropped in the lengthy birdie putt to move to 3-under for the tournament.
Thats when a dour Tiger became a bit light-hearted.
After reaching the par-5 15th in two shots, he and his caddie Steve Williams took turns throwing a divot at each other. A relaxed Woods then made the 15-foot eagle putt to move the 5-under.
He concluded his round by stiffing a pair of approach shots on the final two holes to within two feet.
An interesting day, Tiger said with a smirk. I figured something out with my golf swing on the range. I hit it beautifully on the range and started hitting my normal distances. That kind of threw me off when I hit some shots long and made double, but I finally got it dialed in and starting trusting my clubs.
