The 2010 TIME 100

Now that I am five years removed from competitive golf, I, like many of you, have simply become a fan of the game. I have long enjoyed the engaging personality of Phil Mickelson, 39, and the smile that has endeared him to many fans. We have all celebrated Phil's victories and cried with him over the struggles faced by his wife Amy and his mother. Family has always been my priority, and their presence outside the ropes has underlined every win. After he won this year's Masters, I imagine that slipping into a third green jacket would not have meant nearly as much to Phil had he not first slipped into the embrace of his family. That's the way it should be. My wife Barbara and I are proud to call Amy and Phil friends.
