On a volatile Saturday at Torrey Pines, a handful of heavyweights moved into position to win the U.S. Open championship.

Louis Oosthuizen, the 2010 Open champion and runner-up in the PGA Championship last month, poured in a 51-foot eagle putt on the 18th green to leap into a three-way tie for the lead with 36-hole co-leader Russell Henley and Canada’s Mackenzie Hughes at 5-under-par 208.
