PGA Tour — Shane Lowry was far from his best as he posted a three over 75 to slip another seven places to tied 54th in the Valero Texas Open.

The Offaly man is seven over par and a massive 16 shots behind the impressive local hero Jimmy Walker, who birdied the 18th for a 69 to open up a four-shot lead over Jordan Spieth (71) at JW Marriott TPC San Antonio.

Lowry started on the 10th and went out in level par, mixing two birdies with two bogeys.

But he got frustrated on the run home and a cold putter didn't help as he bogeyed the first, second, sixth and seventh before clawing a shot back at the par-five eighth. Even that birdie was somewhat frustrating as he had a 14 footer for eagle and missed that too.

Despite it all, the Clara native kept his spirits up with a quick tweet about today's GAA action.

Web.com Tour — West Waterford's Seamus Power shot the lowest round of his rookie year — a superb 66 — to surge into the Top 10 at the  Chitimacha Louisiana Open presented by NACHER.

The former Irish amateur star, who made his first cheque of the year in Chile last week, had six birdies and just one bogey in one of the rounds of the day to move up 15 places to tied 10th.

He's on nine under par at Le Triomphe Golf and Country Club in Broussard, just five shots behind Rick Cochran III, who shot a 65 to lead by one stroke from China's Hao Tong Li and overnight leader Rhein Gibson from Australia on 14 under

Power is 151st in the money list and in need of a decent finish due to the frequent re-ranks on the second tied US tour.

Azalea Invitational — Chris Selfridge birdied his last four holes to move to within four shots of the lead entering the final round of the prestigious Azalea Invitational at the Country Club of Charleston.

The University of Toledo and Moyola Park star fired a four under 67 to leap into a tie for fourth place on eight under par at the South Carolina event.

Todd White (69) and Andre Tourinho (68) lead by one stroke on 12 under from Bryson Nimmer with Selfridge tied for fourth with Atlanta's Will Chandler.

Balbriggan's Robbie Cannon, who is also Selfridge's strength and conditioning coach, had a tougher day at the office, posting just one birdie in a 75 to slip back to tied 38th on two over.
