It was a tale of two rounds — or two nines — for Rory McIlroy. Following his spectacular nine-under 63 in the first round, McIlroy, who started on no. 10 Friday, quickly dropped out of the lead after struggling on his first nine, which included three consecutive double-bogeys. He posted seven-over 43 on the back nine.
Despite his rally on the front, he still shot 15 strokes worse than the previous day, with a six-over 78 in the second round of The Memorial.
