A clutch shot by Phil Mickelson. A South African meltdown. That was all it took for the Americans to put themselves on the verge of another rout in the Presidents Cup.

Mickelson hit a 7-iron around a tree and onto the 18th green to secure half a point in a match the U.S. team once trailed by three holes. Louis Oosthuizen and Charl Schwartzel, a lone bright spot in foursomes, couldn't buy a par and blew a 3-up lead with five holes to play.

The Americans won the rain-delayed session 3-1-1, pushing their lead to 14-8 over the International team going into 12 singles matches.

They only needed three wins and a halve to win the cup outright for the eighth time in 10 tries.
