A look at the key hole Saturday in the third round of the Masters:
STROKE AVERAGE: 4.474
KEY FACT: Leader and defending champion Jordan Spieth pushed his drive into the trees and wound up making double bogey — after a bogey at No. 17 — to give the pack chasing him a realistic chance. Two-time champion Bernhard Langer, at age 58, made a twisting 15-foot putt to save bogey and booked a place in the next-to-last group.
