After a second-round 61, Tiger Woods built a seven-shot lead at the WGC-Bridgestone Invitational at Firestone Country Club in Akron, Ohio. The 9-under 61 equaled Woods' best round on Tour and tied the course record he set at Firestone in 2000.
Now he'll try to emulate Friday's success and stretch his lead. Keegan Bradley and Chris Wood are tied for second at 6 under. Bill Haas and Henrik Stenson are another shot back. Players will go off in threesomes from split tees on Saturday as inclement weather had been expected later in the day.
