It was as though David Ortiz held another team meeting last night at Busch Stadium, only this time with the Cardinals joining the Red Sox in the corner of the third-base dugout.

The message: Enough with the clumsy errors. Enough with the bad baserunning. Enough with the controversial umpire decisions that require exhaustive postgame readings from the rulebook.

So the Cardinals and the Red Sox went out and played a beauty of a Game 5 of the World Series. When it was done, Jon Lester bested Cardinals starter Adam Wainwright, and the Red Sox, with their 3-1 victory, moved a step closer, a game closer — if you will, a whisker closer — to a World Series championship that few thought possible back in spring training.

Are you ready, Red Sox fans?

It’s been a long time since the year 1918 has been relevant to anything pertaining to modern-day Boston baseball, but here we go again: The Red Sox have two chances to do something that hasn’t happened since, well, 1918.

And that’s win a World Series at Fenway Park.

All because of what they did last night in St. Louis.

Lester, now 3-0 in three career World Series starts, allowed only one run in 72⁄3 innings, that coming on a Matt Holliday homer in the fourth inning. Boston’s Mr. October of the slab has allowed just one run in 21 World Series innings.

Wainwright matched Lester for six innings, allowing nothing more than a first-inning RBI double by the Speaker of the House, David Ortiz.

Ortiz had three more hits last night and has a .733 average for the Series. Such is his command of this Fall Classic that, after the game, Cardinals manager Mike Matheny was posed this preposterous, unfair question: Win or lose, is David Ortiz the MVP of this World Series?

“That’s not even a conversation we’re even thinking about,” Matheny rightfully said. “We’ve got games to play. We’ve got two games we can still win here. So that kind of stuff isn’t even on our radar.”

The Red Sox finally pulled away in a nail-biter seventh inning, which was highlighted by an RBI double from catcher David Ross. How cool is that? Idled by concussions earlier this season, Ross steps out in the biggest game of his life and gets the biggest hit of his life.

“I know David makes it look easy,” Ross said later. “It’s work for me.”

But speaking to the media after the game was pure joy for this large but gentle soul whose smile screams a love of baseball.

“I’m sitting here talking to you people with a World Series logo behind me,” he said. “I’m stoked.”

With one out and runners on first and second, Ross stepped into the batter’s box with Lester waiting on deck. One couldn’t help but wonder: If Ross didn’t do anything, could the Sox allow Lester — The Worst Hitter Ever — to take his cuts?

It had the potential to be yet another move, or non-move, by Red Sox manager John Farrell to throw into the ever-growing pile. But Ross hit a ground-rule double to left, bringing home Xander Bogaerts and giving the Sox a 2-1 lead. End of the wondering and any would-be controversy.

Lester was allowed to hit and bounced back to Wainwright. Jacoby Ellsbury then singled home Stephen Drew. Ross was tagged out at home trying to score from second on Ellsbury’s bloop single, ending what could have been the most talked-about inning of the season but instead is just another happy clipping for the scrapbook.

Would Farrell have hit for Lester?

“No,” said the manager, and then he said it again: “No. Even if the game was tied. Where his pitch count was, as effective as he was, we were looking to get at least one more inning out of him. We were able to do that. And David Ross comes through big with the go-ahead run.”
