Sergio keeps on

Sergio just birdied 3 to go to 4 up - Stricker hit his a little too hard and it lipped out for par.

Els, Romero, Broadhurst, DiMarco, and Harrington are 5 under. Green's having one helluva day - 64 on the day, one over low round for any day at any major - but he's done so he can't improve his 5 under. Els is the biggest name chasing Sergio who has a real chance; he's having a good day. (Tiger? He's 9 shots back and playing the eleventh hole. It would talk a meteor shower...)
