Treanor has played 12 years in the minors, ten before his first taste of the big leagues. In 2008 he spent most of the year on the disabled list. His last time before that in the minors was 2004 in Albuquerque. Matt began his career in 1994 in the Kansas City Royals system. He would spend three years there before being traded to the Marlins. He was originally a 4th round pitch of the Royals in the 94 draft out of Mater Dei High School in Santa Ana, California. He was traded straight up to the Marlins for Matt Whisenant just before the trade deadline in 1997.
Cougar fans would remember him for the 1999 season in which he hit .286 in 86 games with 10 homers and 53 runs batted in. He also made a stop to Geneva in 2001 on a rehab outing in which he gota hit and two walks in his three plate appearances. His big moment for the Cougars came in game three of the Midwest League semi finals in which he hit a homer in the 8th inning off of Burling pitcher Brandon Whatley. The Cougars would eventually lose that game.
