One of the longest hitters on the European Tour, Colsaerts won the Volvo World Match Play in May with a 1-up win against Graeme McDowell. Before defeating McDowell, Colsaerts beat Justin Rose, Brandt Snedeker, Paul Lawrie, and Charl Schwartzel.
Colsaerts could be a giant-killer this week at Olympic. It's too early to predict where he'll be by Friday afternoon on the leaderboard, but his star is rising.
