(Reuters) - Zach Johnson acknowledges that long, difficult Whistling Straits is not his favorite PGA Championship venue, but do not rule him out this week.
He tied for third at the Wisconsin course in 2010 and returns on an emotional high as the current holder of the oldest trophy in golf, the Claret Jug.
St. Andrews is not his preferred British Open venue either, but that did not stop Johnson from winning there last month and becoming a dual major champion eight years after claiming a Masters green jacket.
