Amnesia is a ballplayer’s best friend.

File it and forget it.

Monday was hardly a day of mourning at Comerica Park. Nobody wore black armbands in memory of an American League Championship Series the Tigers had firmly within their control after its first 16 innings.

The Tigers insisted they took an eraser to their memory 5 minutes after Boston’s amazing 6-5 Game 2 comeback victory.

“It’s the nature of the game” said Torii Hunter who offered no playoff eulogies.

The beauty of baseball is that the solemn night quickly surrenders to the optimistic morning. There’s salvation in the knowledge that the sport offers little time for brooding and boasting. Hunter can’t wait for another desperate lunge over the rightfield wall to potentially save a home run. Joaquin Benoit can’t wait to get the call in the bullpen to get ready to protect a ninth-inning lead — perhaps as early as this afternoon’s pivotal Game 3.

It’s crazy panicking. It’s downright dumb fretting that the Tigers gave away something Sunday they might not ever recover. If anything the Humbling in the Hub might help the Tigers as they press forward in this series. If they didn’t know it already Game 2 provided another reminder of the fickle nature of the sport.

Sorry to disappoint the doomsayers but Game 2 wasn’t a disaster. The Tigers still accomplished their primary objective entering the first weekend of the ALCS splitting the first two games at Boston at the very least. They have home-field edge the remaining five games. Take care of their business the next three days and they’re heading back to the World Series for the third time in the past eight years.

“The series is probably where it should be” Jim Leyland said. “It was a tough one obviously. But that’s — we’re used to that. We’re used to being able to turn the page. And I’ve always said this. In baseball when you win you don’t get long to celebrate. And the good thing when you lose you don’t have to wait long to play again.”

It was a week ago today when the Tigers stared at probable series elimination when Oakland took a 3-0 lead into the bottom of the fifth inning in Game 4 of the ALDS. They couldn’t hit. And then Jhonny Peralta blasted a game-tying three-run homer.

And the Tigers won that game as well as their next two.

And don’t forget about another late-inning playoff collapse. Last year the Tigers had the champagne rolled into their clubhouse ready for popping after Game 4 of the ALDS against the A’s. But Jose Valverde couldn’t hold a two-run ninth inning lead.

And what followed?

The Tigers won their next five games finishing off the A’s in Game 5 and sweeping the New York Yankees in the ALCS.

File it and forget it.
