Zimmerman, 27, was acquired by the expansion club in February via a blockbuster trade with LAFC, giving them a defensive cornerstone en route to becoming the sixth expansion club in MLS history to clinch a spot in the Audi MLS Cup Playoffs during its inaugural season.
Zimmerman also finished as runner-up in Defender of the Year voting last season while with LAFC, though he did earn All-Star and Best XI recognition in 2019.
Nashville had a goals against average of 0.96 goals per game, the best of any expansion club in league history, and they tied for the league-lead with nine clean sheets. The club allowed 22 goals, third-fewest in the league, and only two goals more than the league leaders.
Zimmerman not only led Nashville’s backline, but he also chipped in three goals and one assist, placing him among the club's top scorers. One of those goals was Nashville's first-ever goal in their Feb. 29 debut game against Atlanta United at Nissan Stadium before nearly 60,000 fans.
The No. 7 overall pick in the 2013 MLS SuperDraft, Zimmerman began his MLS career with FC Dallas before moving to LAFC in 2018 and then to Nashville SC this year. On the US men's national team stage, Zimmerman has two goals in 12 appearances.
Other players to register double-digit vote percentages were the Philadelphia Union's Mark McKenzie and Columbus Crew SC captain Jonathan Mensah. Zimmerman, however, won out with 28.37% of the final vote.
