A glance at Friday's second round at the Masters:
Leading: Rory McIlroy followed his 65 with a 69 and held onto the top spot with a 10-under total of 134.
Pursuing: Jason Day, who shot the low round - 64 - is two back at 136, followed by Tiger Woods and K.J. Choi at 137.
And Phil? Defending champ Phil Mickelson is among 10 players tied for 20th at 2-under 144.
Shot of the day: Woods hit an 8-iron from the right rough 150 yards to set up a 12-foot putt for the last of his nine birdies on the day.
Key stat: McIlroy's bogey-free streak of 29 holes ended when he failed to get up and down out of a bunker at No. 12.
Noteworthy: U.S. PGA champion Martin Kaymer, the world's top-ranked player, and two other major winners from last year - Graeme McDowell (U.S.Open) and Louis Oosthuizen (British) - failed to make the cut at 145.
Quoteworthy: ''I don't really care what anyone else does. I don't need to know.'' - McIlroy, on whether he was worried seeing Woods climb the leaderboard.
