The leaderboard remains fluid at the Valero Texas Open, where Billy Horschel still has a share of the lead at the moment, but he has a lot of company.
Horschel and Martin Laird are tied at 10 under -- Horschel is through eight and Laird through nine -- but four others are within two of them.
That includes Rory McIlroy and Jim Furyk, both of whom are just a stroke back.
McIlroy has birdied three of his last five holes and each of his last two, making the turn in 33 to get as close to the lead as he's been all day.
K.J. Choi and Marcel Siem are another stroke back at 8 under.
What was once a three-shot lead for Billy Horschel is now gone.
Horschel is 1 over through his first four holes and hasn't come close to giving himself a look at birdie. His lone bogey came on the par-4 fourth, where he missed the green right then took three more to get home, missing a 12-footer to save par.
Meanwhile, Martin Laird has sped up the leaderboard with four birdies in his last five holes to get to 9 under and a share of the lead -- for now.
Four others are two back, including Rory McIlroy ad Jim Furyk.
A win would get Horschel into the Masters next week, and it would be his first on the PGA TOUR.
But there's a very long way to go, and Horschel has not been great in final rounds this season. Five of his nine final rounds have been in the 70s or higher, including an 85 at Bay Hill and a 75 in San Diego.
Billy Horschel is in unfamiliar territory as he gets set to tee off (12:35 p.m. ETC) in the final round at the Valero Texas Open.
This is the first time Horschel has held a lead through 54 holes on the PGA TOUR, but he's been hot lately, finishing second last week in Houston and having racked up nearly $1 million in earnings before the calendar turned to April.
A couple of reasons why Horschel is where he is, with an invitation to the Masters awaiting should he hang on.
-- Through three rounds at TPC San Antonio, which has some of the largest greens on TOUR, Horschel leads the field in putting average and strokes gained-putting.
-- Of the seven bogeys Horschel has made this week, five times he has followed with a birdie on the next hole. That also leads the field.
Now the question is, can he win?
Jim Furyk and Charley Hoffman are two strokes back, while three others, including Rory McIlroy, are another two back. The wind is also blowing at TPC San Antonio.
The good news is history is on Horschel's side. Each of the last two winners there -- Ben Curtis and Brendan Steele -- held the lead going into the final round.

SAN ANTONIO -- Golf is a game of momentum. So much so, the PGA TOUR has a special “bounceback” statistic. It tracks a player’s ability to make a birdie or better following a bogey or worse. Billy Horschel has made seven bogeys this week and has followed up five of them with birdies. That’s remarkable. It’s enabled Horschel to keep building momentum and confidence during rounds.
This week has been special for the Florida graduate. On the season, Horschel successfully bounces back only 20 percent of the time. To give you an idea of how hard it is to make a birdie following a bogey, Steve Stricker leads the TOUR at 47 percent. Horschel is at 71 percent this week. It helps that Horschel also leads the tournament in strokes gained-putting.
In touch: Jim Furyk’s six-foot birdie putt on the 18th hole was important enough for him to deliver a fist pump. It’s not that Furyk never makes six-footers and it’s not the fact he shot 69. Furyk’s birdie on the final hole ensured he would play in the final group, going head-to-head with Billy Horschel. Furyk begins the final round with lots of experience and just two shots separating him from the leader.
Close: You can tell Rory McIlory is close to playing very well but he continues to lose shots during the round. He laid up into a bunker at the par-5 second hole and drove into the rough at the eighth. Both shots led to pars. McIlroy three-putted for bogey at both 10 and 11, then hit a bad wedge into the 17th and had a bad bunker shot on the final hole. Those are six shots that could have led to six birdies with better execution. Every player hits bad shots and gets bad break during a round of golf, but McIlroy is still losing too many shots during a round.
Hard hole: The 13th hole was mean par 3 on Saturday. It was set up at 228 yards and did not yield a single birdie. There were 82 players who came through, resulting in 43 pars, 37 bogeys and two doubles. When the best players in the world cannot make a single birdie, it’s a hard hole. It played a half shot over par and was the second hardest hole on the golf course.
Texans: Bob Estes and Ryan Palmer are Texans and accustomed to playing in the wind. Estes is from Austin, while Palmer is from the plains of Amarillo. Both felt comfortable on the course during Saturday’s gales. Palmer shot a bogey-free 68, while Estes carded a 69. Estes says modern equipment creates a higher ball flight and it takes practice to control the lower trajectory needed in the wind.
