Louis Oosthuizen birdied the ninth hole at Oakmont Country Club on Saturday to card 65 for his second round at the US Open, which set him into a share of 12th place at level-par for the tournament.
The world number 14 went 10 shots better than his opening 75 and climbed 67 places up the leaderboard. He joined a six-way tie for 12th that included Adam Scott and Daniel Berger, all of whom were four strokes behind 36-hole leader Dustin Johnson.
Oosthuizen was firing on all cylinders in the second round, which was halted firstly due to inclement weather and then due to bad light at the end of the day. Most of the 33-year-old’s scoring was done on Friday afternoon.
He started on the 10th and mounted his charge with a string of birdies from the 12th to the 14th. His round included bogeys at the first, 10th, and 17th, but they were speed bumps in a one-way traffic lane. The 2010 Open Champion put together four consecutive birdies from the third to the sixth before coming off the course on Friday evening.
On Saturday he found rhythm with pars at the seventh and eighth, then sank a 25-footer for birdie at the ninth to make the clubhouse on level-par after 36 holes.
Charl Schwartzel also clawed his way back into the tournament when he carded a second-round 68. The 2011 Masters winner shared 46th place on four-over-par, one shot behind Branden Grace, who was tied for 36th.
