Rory McIlroy and second rounds haven't always gone together like fresh-cut greens and made putts. Friday at the British Open, he'll try to improve his record in that area as he starts the day at Royal Liverpool with a one-shot lead.
He'll likely need another good round to remain atop the leaderboard, with World No. 1 Adam Scott and Tiger Woods among his closest pursuers, as well as Sergio Garcia and Rickie Fowler – all four among 17 players 3 shots back or less. We'll also keep an eye on the cut line, with is the top 70 and ties.
