Career
Baumann is a product of the Football Club Basel youth system and usually plays as a centre-back but has also been deployed at right-back or in midfield. He first came into the Basel team at the end of the 2006/07 season but played just one game during that campaign and one the following season, so he was loaned out to Football Club Concordia Basel in January 2008 for six months to gain first-team experience. He became an important player for Concordia, playing thirteen games and scoring one goal, during his time there.
He returned to Football Club Basel in the summer but Concordia were keen to acquire his services for another season and Basel allowed him to move there on another six month loan spell.
He returned to Basel in the Summer of 2009 and joined on 2 September 2009 on trial to Football Club Schalke 04. He joined Servette Football Club in 2010 after spells with Football Club Solothurn and South Carolina Kriens.
He was one of Servette"s most used players during the 2010-2011 Swiss Challenge League season. After a promising start in the top flight in the 2011-2012 season, Baumann severely injured his knee in a match against Football Club Lucerne, and missed the rest of the season.
In January 2016 Servette Football Club announced that they were re-signing Patrick Baumann.
He initially signed on a 6-months contact with an option for 2 more seasons as well as integration into the academy.
