Your first round leader after the first round of the United States Open is American Michael Thompson of Tucson, Arizona.
Thursday at the Olympic Club in San Francisco, Thompson shot a four under par and currently has a three stroke lead on an impressive quintet of golfers–2001 PGA Champion David Toms of the United States, American Nick Watney, who became the second consecutive golfer in a major championship to record a double eagle, 2010 U.S. Open Champion Graeme McDowell of Northern Ireland, Justin Rose of England, who won the 2012 WGC Cadillac Championship, and a guy by the name of Tiger Woods, who has won every significant golf tournament in his career.
