Tiger Woods carded a second-round nine-under-par 63 in Ohio to take the lead in the Memorial Tournament. On a warm, lazy day at Muirfield Village, Woods came to life with four straight birdies on the front nine, then brought the gallery to its feet with a superb finish which boosts his hopes of retaining his title.

After a delicate blast from the sand barely climbed out of the bunker on the 16th, he holed the chip for par, then finished with two birdies.

Until then, the best round of a wind-free day was Ernie Els' 64.
