In 1969, Allin turned pro and qualified for the
PGA Tour on his first attempt citing the fact that golf was no "big deal" compared to war. Allin's first win on the
PGA Tour came in 1971 at the
Greater Greensboro Open when he defeated
Dave Eichelberger and
Rod Funseth on the first extra-hole in a playoff. He would win five times in five years between 1971 and 1976. His best season was in 1974 when he won the Doral Ryder Open and the Byron Nelson Classic, which propelled him to a ninth-place finish on the money list. His best finish in a
major was a T-10 at the 1974
U.S. Open and the
1975 PGA Championship. He had 3 dozen top-10 finishes in PGA Tour events in his career; his last win came at the 1976
Pleasant Valley Classic. After reaching the age of 50 in October 1994, Allin began competing on the
Senior PGA Tour. He was nominated for
Rookie of the Year in 1995, after an outstanding first full season. He also shot a Senior Tour record low round of 61 at the FHP Healthcare Classic that year. His lone Senior tour win came in 1997 at the
American Express Invitational where he 2-putted from 60 feet on the 54th hole to win by one stroke over Jim Colbert. He competed five full seasons before electing to leave the tour despite being exempt for the 2000 season. Allin devoted the last years of his life to teaching at the
San Diego Golf Academy and authoring his instructional manual,
Center-Line, as well as an instructional DVD,
Preferences. He lived in
Boulder City, Nevada as well as California. He died in
Hemet, California at the age of 62 from multiple forms of cancer. ==Professional wins (9)==
