Rimando made his first save in the 7th minute on a point-blank shot by Robert Lewandowski. But less than a minute later, Lewandowski found the net, beating a leaping Rimando with a crafty chip from the top of the 18-yard box to give Bayern an early lead.
"I think he mis-hit it a little bit," Rimando said. "It bounced up and it went across and dipped down to my left. I want that one back, but at the end of the day, you win some, you lose some, and we responded well."
MLS went ahead in the 70th minute when Donovan chested down a long cross from Portland's Diego Valeri at the top of the box, shed a Bayern defender and knocked a right-foot blast into the back of the net.
Before the ball was put back into play, Donovan who was named MVP of the match exited the pitch to a large ovation.
"Landon can always impact the game, wherever he's at, whatever team he's on," Rimando said. "Credit to him, to come up here and compete and get us that goal that's class from a class player."
Rimando turned away a Pierre-Emile Hojberg strike in the 32nd minute and made another leaping save in the 38th, batting away a six-yard shot from Xherdan Shaqiri. He'd make two more stops just before the half: A sliding kick save in the 43rd minute on a shot from US National teamer Julian Green and a block on a 44th-minute shot by Shaqiri.
Rimando, clad in neon green for the match, was subbed out at halftime in favor of D.C. United's Bill Hamid. Bayern brought on the bulk of its World Cup standouts in the 79th minute, but the MLS side held firm.
O Landon Donovan plays just 23 minutes, but scores the game-winning goal to earn MVP honors in his 14th All-Star match.
