Jordan Spieth, the 21-year-old who's running away from the field at the Masters, has a chance to set the 36-hole record at Augusta.

He entered the back nine of his second round at 11-under.

He's now 12-under after 10 holes. If he gets to 14-under he'll break Raymond Floyd's 39-year-old record for lowest score after 36 holes.
