Jon Rahm builds Mexico Open lead as Graeme McDowell makes cut

World number two Jon Rahm is two shots clear of the chasing pack following the second round of the Mexico Open at the Vidanta Vallara, while Graeme McDowell just made the cut for the weekend.

The Northern Irishman is in a tie for 58th, 10 shots off the summit after a second consecutive round of 70 which put him just inside the cut mark.

Rahm birdied all four of the day's par fives to lead at 12 under.

"I feel like I might be a little bit more satisfied with today's score than yesterday," Rahm told PGA.

"Yesterday I felt like I was really under control and relatively speaking stress free. Today was a bit more of a grind, but still a really good round of golf."

He was trailed by American Alex Smalley at 10 under. Four of Smalley's compatriots - Adam Long, Andrew Novak, Cameron Champ and Patrick Reed - followed on nine under.

England's Aaron Rai shared the ninth spot with five others on eight-under.
