Following two days of stops and starts, the second round of the Zurich Classic finally wrapped up at 11:15 am on Saturday morning with the team of Jon Rahm and Ryan Palmer sitting alone on top at 15-under par.
Starting the round tied for 17th, the duo of Rham and Palmer rocketed up the leaderboard at TPC Louisiana with a blemish-free 7-under 65 in foursomes play.
One back were overnight leaders Brian Gay and Rory Sabbatini, who arrived at the final tee box (the par-3 9th hole) holding a one-shot advantage, but a surprise double bogey sent the first-round leaders tumbling back into a tie for second at 14-under par, alongside Peter Malnati and Billy Hurley III (67).
Also ending on a sour note was the team of Kevin Kisner and Scott Brown, who dropped a shot on the par-5 18th to post 69, and a two-day score of 13-under par. They were T4 alongside the teams of Scott Stallings and Trey Mullinax and Russell Knox and Brian Stuard.
Four more twosomes were one further back at 12 under, headlined by a team comprised of a pair of European veterans, and former major winners, in Graeme McDowell and Henrik Stenson.
