Russell was 8-4 with a 3.86 ERA for the University of Texas in 2007 after transferring from junior college. He was then selected by the Cubs in the 14th round of the 2007 amateur draft. Russell was signed by scout Trey Forkerway and made his pro debut that summer with the AZL Cubs, throwing two perfect innings in one outing with the club. He was then promoted to the Peoria Chiefs, where he allowed no earned runs and struck out 9 in 7 innings over two starts.
When Russell saved a game in 2012, he became part of the 4th father-son duo to record saves since MLB first kept them as an official stat. He and his father joined Julio Navarro and Jaime Navarro, Pedro Borbon Sr. and Pedro Borbon Jr. and Steve Grilli and Jason Grilli.
Russell married Nikki Witt, the daughter of Bobby Witt, who had played with Russell's father.
