Saturday will be the first opportunity for U.S. captain Fred Couples to hide two struggling players. One candidate at this point is Hunter Mahan, who is the only American to drop two matches at Muirfield Village. After losing in Thursday's best ball alongside Brandt Snedeker, Mahan and Friday partner Bill Haas were rolled by Ernie Els and Brendan de Jonge 4 and 3 in foursomes. After a season that featured a strong major championship showing and a runner-up in the Accenture Match Play, Mahan was expected to bring more than he has to this year's Presidents Cup. The question is whether he'll have a chance before Sunday to redeem himself.
