A second round of 68 has moved Matt Wallace firmly into the mix at the midway point of the US Open at Pebble Beach.

The 29-year-old Moor Park Golf Club honorary member followed up his one-under-par opening round with a three-under score for his second 18 holes at the California course to leave him in a share of sixth place, five shots behind leader Gary Woodland.

The world number 26 made six birdies in his second round as he seeks to emulate his third place in last month’s US PGA Championship, his best major result to date.

That tournament was won by the player Wallace will partner in the third round later today, Brooks Koepka, who is seeking a hat-trick of US Open titles and a fifth major in his last nine starts.

Chesson Hadley, Matt Kuchar and Chez Reavie are also on four-under, one shot behind Aaron Wise and Rory McIlroy.

Woodland’s closest challengers are Justin Rose, who is on seven-under, with Louis Oosthuizen a shot further back.
