Freiburg was heading for an upset win at 2-0 up in the 81st minute before Bayern's young midfielders changed the game, 20-year-old Tom Bischof scoring twice with low shots from distance and 18-year-old Karl slotting in a low cross from Alphonso Davies to turn the game on its head.
Harry Kane was out with an ankle issue ahead of next week's Champions League quarterfinal against Real Madrid and Nicolas Jackson was suspended so Serge Gnabry was tasked with leading the Bayern attack but made little headway.Bayern's defense was at fault for Freiburg's opening goal, giving Johan Manzambi plenty of space to cut in from the left flank and line up a powerful shot past Manuel Neuer.
Back in the team after injury, Neuer made strong saves in the first half but blundered for Freiburg's second, leaping out of his goal to palm a corner straight to Freiburg striker Lucas Holer for an easy second.
Michael Olise missed a huge chance for Bayern but it was Bischof who made the breakthrough, scoring once from outside the area in the 81st, then again in added time as Freiburg was caught out by Bayern's quick corner routine. Davies' assist for Karl's winner marked an encouraging return from a hamstring injury for the Canada left back ahead of the World Cup.

Dortmund's late double

Second-placed Borussia Dortmund left it late, too, scoring both goals in added time in a 2-0 win over third-placed Stuttgart to keep the gap to Bayern at nine points.
Dortmund created little until Karim Adeyemi picked up a deflected ball in the penalty area, beat Stuttgart midfielder Atakan Karazor and slammed it past goalkeeper Alexander Nubel. Dortmund made sure of the points with Julian Brandt's goal on the counter.Some Stuttgart fans rushed toward the field during the celebrations for Dortmund's second goal and gathered behind the advertising boards. A folding chair was thrown onto the field soon after and Stuttgart players were speaking with supporters after the final whistle, seemingly trying to calm the situation. (AP)
