Weghorst double and Baumann mistakes see Wolfsburg beat Hoffenheim
Hoffenheim goalkeeper Oliver Baumann fluffed two routine saves as his side lost 4-1 to Wolfsburg and missed the chance to move within a point of the top four.
The usually reliable Baumann made his mistakes in the second half to hand Wolfsburg victory and end a six-game unbeaten run for Hoffenheim.
"It is really annoying because I saved pretty much everything else," Baumann told Sky.
The defeat is a blow to Hoffenheim's hopes of European qualification. Julian Nagelsmann's side remain on course for a Europa League berth in seventh, but are four points adrift of the top four.
"If we are no longer favourites for the Champions League, then that is probably deserved after today," said Baumann.
Adam Szalai found the net at the end of slick counter-attack to put Hoffenheim in front on nine minutes.
Andrej Kramaric then missed a penalty for the hosts, before Wolfsburg's William curled in a superb equaliser just before half-time.
Despite having made several fine saves in the first half, Baumann gifted Wolfsburg the lead with 20 minutes to go when he let Wout Weghorst's soft header slip through his fingers at the near post.
The Hoffenheim keeper was beaten at his near post again by a fierce shot from Maximilian Arnold.
Weghorst struck again in the 89th minute.
The puts Wolfsburg move a point behind Hoffenheim in eighth.
Bayern Munich have the chance to go four points clear at the top of the table when they face Nuremberg in Sunday's late match.
