Geoff Ogilvy, winner of the 2006 US Open, turns 38. The Australian has 13 professional wins under his belt, including eight on the PGA Tour and four on the European Tour. He was two strokes off the lead through 36 holes at the Open, then a shot back after 54. On the final day, five different men had the lead, and he won with a par on 18 while Phil Mickelson, Jim Furyk, and Colin Montgomerie all fell apart.
Mark Calcavecchia, winner of the 1989 Open Championship, turns 55. He won 31 titles overall, 13 of those on the PGA Tour, and also finished second at the 1988 Masters. The field was deep at Troon that year, with Calcavecchia not even in the Top 10 after a day, and three strokes off the lead through 54 holes despite shooting 9-under. His final-round 68 forged a three-way tie with Greg Norman and Wayne Grady at 13-under and instituted the first four-hole playoff in Open history. Calcavecchia stormed through the playoff with a par followed by three straight birdies to finish it at 2-under, while Grady parred all four holes. Norman was also 2-under through three holes, but when he missed his birdie putt on the final hole, Calcavecchia took the Claret Jug.
Mick Soli, who played on the PGA Tour from 1979 to 1985, turns 61. He is annually hailed as one of the top golf pros in the country.
