This time of year most major leaguers look at the interview room as if it’s a torture chamber. David Ross looked at it like it was Disney World.

There are improbable heroes and then there was Ross last night, the light shining on him in the game’s most brilliant moment. When you’re batting .125 in the World Series, improbable hero would seem to be a heroic understatement, but that’s what the Red Sox’ scrap-iron catcher with the “Duck Dynasty” beard became after he lined a ground-rule double just inside the chalk at Busch Stadium that caromed into the stands, driving home what would become the run that sent the Red Sox back to Fenway Park one game from winning the World Series for the third time in 10 seasons.

Ross’ one-out double in the seventh inning scored Xander Bogaerts to break a 1-1 tie, set the table for what became a 3-1 Red Sox victory over the St. Louis Cardinals in Game 5, and gave the Sox a 3-2 Series lead that seemed to take the breath out of a sellout crowd of 47,436 towel-waving Cardinals loyalists.

If there was a more unlikely guy to have done in St. Louis than Ross, it’s difficult to think who it would have been. Certainly Ross couldn’t think of anyone else, considering the harrowing season he’s had.

“There’s a reason we hit at the bottom of the order,” Ross joked on a night when he went 2-for-4 and was as brilliant in his primary job — orchestrating the pitching approach of Jon Lester — as he was in a generally less comfortable place for him: the batter’s box.

“There’s a reason why I hit in the 8 hole and the 9 hole in the American League. I’m not very good at hitting . . . as opposed to the guys who hit on top.

“We’re facing the best pitching . . . that baseball has to offer. They’re game-planning. They’re switching things up. It’s tough. Hitting is tough, period. I know David (Ortiz) makes it look easy, but it’s work for me.”

Last night, for one magical fall evening, it was much more than work. It was a joy. It was a joy for David Ross to have his moment and a joy for anyone who respects the hardscrabble guys who have to battle all their lives just to keep a job to watch him do it.

David Ross is the guy who carries a black lunch pail. He’s the guy with the dust on his scuffed work boots and 157,000 miles on his pickup. He’s a working stiff who had a moment you only dream about if you’ve gone through all he’s gone through to keep his career alive for 12 years in the big leagues and, this season, to keep his head from exploding after two foul tips in 10 pitches knocked him out of commission for two months with post-concussion syndrome.

“They really dinged me up pretty good,” Ross recalled. “I got home and my wife said, ‘You’re not right.’ They did some tests and concluded I wasn’t right.

“Then I tried to come back too fast, not giving enough credit to really what a concussion is. As athletes we feel like we can get through anything and I couldn’t. I stunk for a good two weeks, three weeks, and my wife finally said, ‘If you don’t tell the doctors, I’m going to.’

“So I did and they did some more tests and they sent me to a specialist in Pittsburgh, Micky Collins. I probably wouldn’t be sitting here if not for him. He showed me I wasn’t right.
