ST. LOUIS -- Jon Lester pitched the Boston Red Sox within a whisker of yet another World Series championship.

Now, this bearded band goes back to Fenway Park just one win away.

Lester bested Adam Wainwright once again, journeyman David Ross hit a tiebreaking double in the seventh inning and the Red Sox downed the St. Louis Cardinals 3-1 on Monday night to take a 3-2 Series edge.

David Ortiz delivered his latest big hit, too, putting Boston in position to capture its third crown in a decade. Not since 1918 have the Red Sox clinched the title at their century-old bandbox.

John Lackey gets the first chance to win it Wednesday night against St. Louis rookie sensation Michael Wacha. A Cardinals victory would set up a most spooky proposition for both teams -- Game 7 on Halloween night.

Ortiz enjoyed even more success in Game 5 after moving up from cleanup to the third slot. He is 11-for-15 (.733) in this Series with two homers, six RBIs and four walks.

He left in a double switch, shortly after legging out a hit, in the eighth. He was OK, and he already had done enough damage to the Cardinals.

Lester enhanced his reputation as an October ace with every pitch. He allowed one run and four hits in 7 2/3 innings, striking out seven without a walk. It was nearly the same line he had in beating Wainwright in the opener.

The lefty, who has won all three of his career World Series starts, had just one scary inning, when Matt Holliday homered in the fourth, Carlos Beltran flied out to the wall and Yadier Molina hit a liner. Other than that, Lester was as sharp as a knife while retiring 12 in a row.

He tweaked himself late but said he was all right. In fact, Lester's biggest brush with major trouble came well before his first pitch.

Lester was getting loose near the warning track when a team of eight Clydesdales pulling a beer wagon came trotting by -- it's a Busch Stadium tradition and Lester moved aside to watch the horses.

He also took a brief break in the seventh. A giant paper airplane floated down from the stands, and some fans cheered its flight as it landed near the mound. Lester handed it to a ballboy, and retired Molina to end the inning.

Lester did it without any flap over his glove. During Game 1, a Cardinals minor league pitcher posted a picture on Twitter of discoloration on Lester's mitt and wondered if some foreign substance was there.

Lester said he merely used rosin for a better grip, and Major League Baseball said it didn't see anything wrong.

Koji Uehara got four outs for his second save. No crazy endings this time, either, following one night with an obstruction call and the next with Uehara's game-finishing pickoff.

The Cardinals went quickly in the ninth, and now need two wins in Boston. They overcame a 3-2 deficit at home to beat Texas for the 2011 title.

Ortiz put Boston ahead with an RBI double in the first, hitting the first pitch after Dustin Pedroia doubled on an 0-2 curve. Ortiz singled the next time up and tied the Series record by reaching base in nine straight plate appearances.

Big Papi and the Red Sox took two of three at the NL park despite playing without a designated hitter. Ortiz became the first baseman, putting slugger Mike Napoli on the bench.

The Red Sox lead the Series despite a .205 team batting average. Ortiz has one-third of the team's 33 hits.

Ross, a graybeard on a team led by scraggly veterans, broke a 1-all tie when he hooked a drive just inside the left-field line, and the ball bounced into the seats for a go-ahead double.

Jacoby Ellsbury later hit an RBI single, and Ross was thrown out at the plate trying to score on the play.

A day after Ortiz delivered a stirring, in-game pep talk to rev up the Red Sox, the Cardinals could've used some inspiration themselves -- perhaps a visit from the good-luck Rally Squirrel from their 2011 title run.

The St. Louis hitters went quietly, a couple slinging their bats after routine popups and fly balls and others questioning the solid calls by plate umpire Bill Miller.

Holliday shook St. Louis' slumber and broke Lester's string with his second home run of the Series. Lester had pitched 16 1-3 scoreless innings in his first three World Series starts before Holliday tagged him.

That was all St. Louis got. Not even a revamped lineup that included the hobbled Allen Craig helped the Cards.

Wainwright changed things the next time Ortiz came up, varying his tempo and delivery. Ortiz still hit it hard while lining out to center.

Wainwright struck out 10 in seven innings, becoming the first Cardinals pitcher to reach double digits in the Series since Bob Gibson did it twice in 1968 against Detroit.

It was a big sports night in St. Louis, with an NFL game between the Rams and Seattle eight blocks away at the Edward Jones Dome. This is a baseball town, clearly: Football tickets sold for $10 on StubHub as kickoff approached, and fans inside the dome loudly booed when the World Series game was taken off the video board.

The baseball fans got to see Lester do more than pitch. He helped himself in the field, knocking down a hard comebacker and swiftly handling a bunt. He also made a dent with his bat, sort of.

Coming in with a career 0-for-31 mark at the plate, he nubbed a ball in front of the plate and was thrown out leading off the third. But at least he broke Wainwright's string of five straight strikeouts, one shy of the postseason record tied by Detroit's Justin Verlander against Boston in the AL championship series.
