Rory McIlroy holds a share of fourth place at the Wells Fargo Championship.

The World No 1 picked up five shots during his second round at Quail Hollow today, which has seen him move to 7-under at the half-way stage.

First-round leader Robert Streb has opened up a two-shot lead at the top of the leaderboard from 10-under.

But Padraig Harrington is struggling during his second round.

He has dropped three shots so-far to slip back to 1-over par.
