CHARLOTTE, N.C. — Angel Cabrera never knows when he's going to play his best golf. This could be shaping up as one of those weeks at the Wells Fargo Championship. On a Quail Hollow course that lets the Argentine hit driver on just about every hole, two exquisite short-game shots late in the second round carried Cabrera to a 3-under 69 on Friday and a share of the lead with Martin Flores going into the weekend.
