John Stertzer joined Real Salt Lake in 2013 as an MLS rookie. In his first year he saw very limited time with the first team, appearing in just 2 games for RSL.
Since, he has seen more game minutes as a squad player in the midfield, normally coming off the bench as a sub. In 2016 Stertzer made 18 appearances starting in 9 of them, marking 1 assist in all competitions. A box to box midfielder, Stertzer competed for minutes against Luke Mulholland and Sunny Stephens.
Stertzer has had an injury riddled career with RSL.
