Birdie: Steve Stricker and Jordan Spieth
The father-son pairing of Stricker and Spieth (not really, but there are 26 years between them), was perhaps unexpected, but the two vindicated Fred Couples' decision. Stricker birdied two of the first four holes to open a 1-up lead. From there, the pair birdied nine of the next 11 holes to overcome a charging Brendon de Jonge, who made eight birdies. And when Spieth showed some 20-year-old nerves with a wet tee shot on No. 18, his veteran partner bailed him out with a testing up-and-down from a buried lie in the bunker to seal a win and keep the U.S. in front heading into Friday.
