 March 2007:  Major/Minor field becomes Jason Smith Memorial Field

Jason Smith was a promising baseball player who started his career at Diamondback Little League. Jason went on to play for North Canyon High School, where he excelled as a pitcher. After graduating high school, Jason joined the United States Marine Corps instead of continuing to play baseball at the junior college level. Jason felt the Marine Corps would make him stronger and more mature in preparation to later enter college and continue his baseball career. On December 31, 2004, Jason Smith was killed by an IED during a tour Iraq. In 2007, DBLL honored this fallen American Soldier by naming the Major/Minor field Jason Smith Memorial Field.
