"It is truly a sad day for me personally and for the Auburn baseball family with the loss of Brent," said former Auburn baseball coach Hal Baird. "While we were well aware of his recent struggles, never the less, it's a stunner to lose someone like Brent. The courage he demonstrated as player at Auburn was also relative the way he fought this battle.
"It's no coincidence that his three years at Auburn was arguably the best three-year period in the history of the program," Baird added. "Brent will be missed by those that he touched and I'm very honored to have coached a person of his character."
During Schoening's three seasons at Auburn, the Tigers won 142 games and participated in the College World Series in 1997. won the SEC Tournament in 1998 and advanced to the NCAA Super Regionals in 1999.
