After an opening round filled with low scores, Quail Hollow showed some of its teeth Friday. Here's how things look at the halfway point of the Wells Fargo Championship, where Webb Simpson and Robert Streb are two shots clear of the field:
Leaderboard: Webb Simpson (-10), Robert Streb (-10), Martin Flores (-8), Patrick Rodgers (-8), Rory McIlroy (-7), Phil Mickelson (-7), Will Mackenzie (-7)
What it means: Streb began the day in front and at one point increased his lead to two shots, but he was later caught by Simpson, whose 67 included a pair of chip-ins.
