Shane Lowry showed some Masters form as Carlos Ortiz claimed the Vivint Houston Open become just the third Mexican to win on the PGA Tour.

Shane Lowry shot his sixth successive round in the sixties to go into the final round of the Houston Open just five shots off the lead.

Shane Lowry gave his iron play another good workout ahead of the Masters and carded a second successive 69 to keep the leaders in his sights in the Vivint Houston Open.

Shane Lowry and Graeme McDowell got their Masters preparations off to a promising start by chiselling out one-under 69s to lie just four shots behind leader Brandt Snedeker in the Vivint Houston Open.

Graeme McDowell has one eye on next week’s Masters and another on resurrecting the Dubai Duty Free Irish Open.
