If Louis Oosthuizen could just figure out the first round of the U.S. Open, he'd be unstoppable. The South African has clearly figured out what to do after.
For a second consecutive year, Oosthuizen followed up a disastrous opening 75 with a scintillating second round. Oosthuizen returned to Oakmont on Saturday morning and finished off a 65 with his eighth birdie:
Oosthuizen's eight birdies was one off the course record set by Johnny Miller during his legendary 63 in the final round of the 1973 U.S. Open.
The good news for Louis is he's back in the tournament. The bad news is that despite his second-round onslaught of Oakmont he's only even par for the tournament.
Oosthuizen's 10-shot swing between rounds, but it's not as big as the 11-shot swing Oosthuizen made last year at Chambers Bay, where he opened with 77 and then shot 66. And if that's any indication of what's to come this week, the rest of the field better watch out. Oosthuizen added rounds of 66 and 67 over the weekend (including a back-nine 29 on Sunday) to finish one stroke behind winner Jordan Spieth.
Two similar scores at a tougher Oakmont this weekend would almost surely result in a trophy.
