With swirling winds once again making scoring difficult at TPC San Antonio, Jimmy Walker played well enough to retain and even extend his lead. Here's how things look heading into the final round of the Valero Texas Open, where Walker leads by four shots:
What it means: Walker began the day with a one-shot lead and was two clear of Spieth, and for much of the day it seemed like the two Texas products would match each other shot for shot. But when Spieth faltered down the stretch, Walker birdied his final two holes to move ahead of the field. Walker looks to win his second title of the season in what amounts to his hometown event.
Round of the day: Matt Jones needed a low round to boost his Masters chances, and a 4-under 68 did just that. The Aussie made five birdies while taking just 26 putts to move into a tie for 11th. Jones likely needs a top-four finish to move inside the top 50 in the world rankings and earn an invite to Augusta National.
Best of the rest: Dustin Johnson made the cut on the number, but after a 4-under 68, he moved all the way up into a tie for 18th through 54 holes. A winner earlier this month at Doral, Johnson began the day with a pair of bogeys before rallying with seven birdies across his next 15 holes.
Biggest disappointment: Charley Hoffman hasn't finished outside the top 20 since this event moved to TPC San Antonio in 2010, but that streak is in jeopardy after Hoffman put up a 7-over 79 in the third round. Beginning the day just one shot off the lead, Hoffman only made one birdie against four bogeys and a pair of double bogeys.
Main storyline heading into Sunday: Walker is sleeping in his own bed this week in nearby Boerne, and he appears poised to turn that hometown advantage into his fifth victory since October 2013. But it's been more than two months since a player converted a 54-hole lead on the PGA Tour. Should he falter, Spieth could be in line for his second win in as many starts.
Shot of the day: Phil Mickelson gave fans a reason to cheer when his approach from 258 yards on the par-5 14th hole nearly found the target for an albatross. Mickelson holed the 3-foot eagle attempt, but that was a rare highlight during a round of 2-over 74 that dropped him into a tie for 11th.
Quote of the day: "I was getting a little too aggressive for this golf course, and it bit me." - Spieth, who played his final seven holes in 2 over.
