Lou Sagastume is retiring after 28 years as the Air Force men's head coach.

Sagastume built Air Force into one of the most respected programs in the nation, compiling a 282-188-43 record in his 28 seasons at Air Force and an overall record of 303-195-43 in 30 seasons. During the 2006 season, he became the 25th coach in Division I history to reach the 300-win plateau.

The Falcons made four NCAA Tournament appearances during Sagastume's tenure. In 1993, Sagastume was named the MPSF Coach of the Year as he guided the Falcons to their best season ever. Air Force posted a 15-5-1 record, won the MPSF's Mountain Division and advanced to the final eight of the NCAA Tournament. Included in that tournament run was a 2-1, four-overtime win at No. 1 Creighton in a game played in sub-zero weather and a driving snow storm.

"It has been an honor for me to coach at the Air Force Academy," said Sagastume. "As much as I have enjoyed the 28 years at this wonderful institution, it is time for me to move on and let someone else continue the progress of the men's soccer program."

The Guatemalan-born Sagastume played on San Francisco's 1966 NCAA championship as a midfielder and later was drafted by the NASL's Oakland Clippers. He also spent the 1975 NASL season with the San Antonio Thunder, making nine appearances. He was an assistant coach at Chico State and a head coach at San Francisco State before moving to Air Force in 1979.

Two of Sagastume's sons, Ryan and Marcus, played soccer for him at Air Force.
