In a match against Hamburg SV, Baumann made three crucial errors that led to a 3–0 loss to Hamburger SV.

International career
Baumann is yet to make his senior team debut for Germany, but has made at least one appearance for all of the nation's youth sides from Under-18 level to Under-21 level. He made his one and only Germany U-18 appearance in a 2–3 home friendly defeat to the Republic of Ireland Under-18 side. All four of Baumann's Under-19 appearances came in friendlies, most notable was a 5–0 home win against the Estonia U-19 side. After then making two appearances for Germany's U-20 side against the Switzerland Under-20s and Italy Under-20s, he made the step up to Under-21 level. For the 2010–11 season, Baumann made four Germany U-21 friendly appearances, conceding six goals during those matches. Since that season, he has made just five Under-21 appearances in three seasons, mainly due to Bayer Leverkusen goalkeeper Bernd Leno being coach Rainer Adrion's first choice.
