The 30-year-old began the day in a tie at the top with Zach Johnson, but quickly assumed the outright lead with birdies on each of his three opening holes.
He closed with three straight birdies, holing an eight-foot putt at the par-five 18th to finish at 12-under 276, five strokes behind American victor Andrew Landry.
In January 2018, Landry had his career-best PGA Tour finish and only top-10 showing on Tour before Sunday when he lost in a four-hole, sudden-death playoff to Spain's Jon Rahm at the CareerBuilder Challenge in La Quinta, Calif. Landry was unquestionably the best ball striker in San Antonio this week, ranking first in SG: Approach, SG: Tee-to-green, and greens in regulation.
"What I've seen lately is that I'm getting questioned a lot by the young guys, about not just golf stuff but life stuff", Johnson said at the RBC Heritage.
"We had the goal beginning this year to play in the Tour Championship, and this it's still my goal", Landry said. "I think that that was really, really key to getting to where I am right now". "He was telling me good shot after good shot, just keep pushing". After a T2 that saw him sign for the lowest final round (66), the 35-year-old four-time TOUR victor was a mixture of disappointed and encouraged. ". I've had some close calls. And you've still got to hit good shots and putt".
Golden State Warriors vs San Antonio Spurs: Lineups, preview & prediction 4/19/18

"I feel like my game's kind of coming into form a little bit", added O'Hair, who with partner Steve Stricker won the unofficial QBE Shootout late past year. "It felt good and I felt like I could get it done today and that's been a while".
"I mean, I was playing good".
"O'Hair chipped in for birdie from 55' 1" on the final hole for his seventh runner-up finish in 345 starts, including one in each of the last four seasons. He's also the third first-time victor in the last five editions of the Valero, joining Steven Bowditch (2014) and Kevin Chappell (2017). Mullinax holed out from 95 feet for eagle at the par-5 14th, sank a 40-foot birdie putt at the par-3 16th and a six-foot birdie putt at 17, then reached the 18th green in two and holed a 16-footer for another eagle and the course record.
Walker ended the week in outright fourth on 14 under and one shot ahead of two-time victor Zach Johnson, who ran up a scrappy six at the last to complete a disappointing 72. The 19-year-old from Chile was the top-ranked amateur in the world. "Starting this week, my putter was working really well", Niemann said.
Joaquin Niemann shot 67-67 on the weekend to finish sixth at 12 under in his pro debut.
