Hunter Mahan polished off a 1-under-par 69 in the second round of the U.S. Open on Saturday morning that included a birdie on the 10th hole to end the round.
Mahan began his round on the par-4 11th and it was pars all the way until the difficult par-4 18th. He would bogey the 18th, then sandwich birdies at one and two between a bogey at the third. His third, and final, birdie of the round came at the par-4 12th and puts him two off the lead at 1-over 141. He'll try and chase down his first major title at Merion over the weekend, trailing by two to Phil Mickelson and Billy Horschel.
