Preston Zimmerman

Hamburger SV

As an 18-year-old, Zimmerman joined the German team Hamburger SV, where he spent most of his time with Hamburg's reserve team. As a striker, Zimmerman played 14 games and scored three goals for the reserves during the 2006–2007 season. Zimmerman was originally signed while he was only 17 but the contract did not become official until he turned 18, skirting FIFA's rules on foreign transfers by minors.

Kapfenberger SV

After a trial stint at Belgian club Cercle Brugge, it was announced on August 29, 2008, that Zimmerman was sold to the newly promoted Austrian Bundesliga club Kapfenberger SV, where he signed a two-year deal. Zimmerman made his Austrian Bundesliga debut as a second-half substitute in a losing effort to SK Austria Kärnten, and scored his first goal for KSV on November 22 against Austrian giants Red Bull Salzburg.

Mainz 05

On January 21, 2010, he returned to Germany, signing an amateur contract for FSV Mainz 05, where he played for the reserve team.

SV Darmstadt 98

On June 2, 2011, it was announced that Zimmerman would be joining recently promoted 3. Liga side SV Darmstadt. After two seasons with the club, Zimmerman left the club on June 17, 2013, with the plan to retire and return to school.

TSV Schott Mainz

In July 2013, he joined six-tier club TSV Schott Mainz. In his first season there, he achieved promotion to the fifth-tier Oberliga Rheinland-Pfalz/Saar with the club.

Zimmerman was a last-minute addition to the U.S. team at the 2007 FIFA U-20 World Cup in Canada following an injury to Johann Smith, but he did not see any playing time. He has since been called up to U-23 camps.

Zimmerman was born in Auburn, Washington. He attended McLoughlin Middle School in Pasco, Washington.
