As a player, he was CGA Match Play champion in 1975, 1976, 1992 and 1994 (the only player to have won the tournament title more was Larry Bromfield, who claimed the trophy eight times from 1912-28); 10 times a top-five finisher in the CGA Stroke Play; into the round of 16 in the 1990 U.S. Amateur; captured six CGA amateur titles; 1990 CGA Public Links champion; and winner of countless state-wide invitationals. He was selected to the Colorado Golf Hall of Fame in 2006.
As a coach, he first started coaching golf at Fort Collins High School in the 1980s. In 1990, he was named Colorado State's golf coach, a position he held for nine seasons. There, he saw the Ram program go from a non-scholarship program into a top 25 team and NCAA Championship contender. CSU qualified for four consecutive NCAA West Regionals under his guidance and qualified for its first NCAA Championship appearance in 1999. The Rams finished tied for 24th at the '99 championships held in Chaska, Minn. Colorado State entered the MasterCard Collegiate Golf Top 25 for the first time in 1998, finishing at No. 23. The Rams also sent their first individual, Nigel Spence, to the NCAA Finals. As a result, Crabtree earned NCAA District VII Coach of the Year honors in '98.Along the way, Crabtree put together one of the nation's most competitive schedules, taking his program to elite tournaments in Honolulu, San Diego, Phoenix and San Francisco. Ram golfers responded to the challenge, posting 11 top 10 team finishes in 15 competitions in 1998-99, including a second consecutive team title at the prestigious Stanford Invitational. The Rams knocked off then-No. 1 Georgia Tech on their way to the `97 title, marking the first time in school history a team had defeated the nation's top-ranked team in any sport.CSU's road to the top 25 and the NCAA Championships was not an easy one. His first class of Rams were homegrown and talented, leading CSU to four team championships, 27 top-five showings and two-runnerup finishes at the WAC Championship.
In 1999, former CSU athletic director Tom Jurich lured Crabtree to Louisville. As he did at CSU, Crabtree steadily built the program, to the point that now Louisville has reached its highest national ranking in men's golf, 21st. The Cardinals have won six tournaments over the last season and a half, and had the nation's top-ranked freshman class last season. Beginning his 13th season as the head coach of the University of Louisville men's golf program, Crabtree has guided the Cardinals to two BIG EAST titles, five regional appearances and two trips to the NCAA Championships. In 2007-08, the Cardinals posted their best finish in school history -- a tenth-place finish at the NCAA Championships at Purdue University. Crabtree has orchestrated a remarkable string of successful seasons for the Cardinals. He has guided his program to four straight regional appearances, two straight visits to the NCAA Championships and a BIG EAST title. In just over 13 seasons at U of L, Crabtree's Cards have posted a top five team, a top seven individual, the top 10 career stroke averages in school history and placed numerous players in the U.S. Amateur tournament.The Cardinals won a school record seven tournaments, which included their first BIG EAST Championship and advanced to the NCAA Championships, where they finished 27th overall in 2006-07.Under Crabtree's direction, the Cardinals have raised the bar each campaign, rewriting the U of L record book at a frenzied pace. In 2003, his young but talented squad notched a 291.5 collective stroke average, nearly six strokes better than the school record of 297.49 posted by the 1999-00 squad in Crabtree's first season in Louisville. With one of the nation's top freshmen classes and senior Grant Sturgeon in the lineup, the Cards swung their way to one of the top seasons ever at U of L.
