Walker joins the Nevada staff as coach Erik Burton's volunteer in 2012.
He continues to be a part of the Wolf Pack family after concluding a playing career at Nevada in 2011. In his playing days, Walker brought a tenacious attitude to the court, something he hopes to pass on to this year's student-athletes.
"It's great to be a part of this program," he said. "I loved it as a player and I can't wait to infuse that love for Nevada tennis into the 2012-13 squad."
