Matt Kuchar began the day one shot behind Sergio Garcia at the Shell Houston Open, but that deficit was quickly reversed. Here's how things look heading into the final round in Texas, where Kuchar now holds a four-shot advantage:
What it means: Kuchar let an opportunity slip away last week in San Antonio, but he appears eager to make up for his miscues this time around. He quickly overtook Garcia at the top of the leaderboard and put some distance between himself and the Spaniard across the back nine. He now appears on the verge of a seventh PGA Tour title, and third in the last 14 months.
Round of the day: Kuchar played in the final group and tied for the day's lowest score - often a useful combination. He birdied three of his first five holes then, after a bogey at No. 9, took control of things across his inward half. Consecutive birdies on Nos. 12, 13 and 14 grew Kuchar's lead, which ballooned to five shots before a closing bogey left him with a 4-under 68.
Best of the rest: Fowler carded a pair of 70s during the first two rounds when scoring was low, then made his move on a day when conditions were somewhat more difficult. Fowler shot a bogey-free 68 Saturday to move into the top five, still in search of a second PGA Tour victory. He reached 14 of 18 greens in regulation, and after failing to make many putts across the first two rounds, finally found a groove with the flat stick.
Biggest disappointment: Jimmy Walker's week in Houston has been rather tumultuous. Walker made a big move up the standings with a second-round 65, but gave most of those strokes back with a 5-over 77 in Round 3. Walker bogeyed three straight from Nos. 4-6 and added a pair of double bogeys on the back nine. After beginning the day in a tie for third, he'll have to wait at least another week to grab his fourth win of the season.
Main storyline heading into Sunday: While no lead is safe on the PGA Tour - just ask Adam Scott - this tournament appears to be Kuchar's to lose. Garcia remains his biggest threat despite a 1-over 73 in the third round, and the two will be joined by Tringale in the final group. With storms in the forecast, tee times will again be moved up but the possibility of a Monday finish remains very real.
