Boston's Jon Lester pitched another outstanding game and David Ortiz continued his phenomenal streak at the plate as the Red Sox beat the Cardinals 3-1 in St. Louis to take a 3-2 lead in the World Series.

The triumph left the Sox one win away from their third championship in a decade.

The Series returns to Boston for Games Six and Seven, giving the Red Sox a chance to clinch at Fenway Park for the first time since 1918.

Cardinals ace Adam Wainwright struck out 10, but with the score knotted 1-1 in the top of the seventh, he walked Xander Bogaerts and then gave up a two-run double to Red Sox catcher David Ross.

Ortiz, who is hitting .733 in the Series with two home runs, six RBIs and four walks, drove in a run to give Boston the lead in the first inning.

Big Papi hit a single in his next at bat, tying the World Series record by getting on base in nine consecutive appearances at the plate.

The Sox will start John Lackey in Game Six on Wednesday, while the Cards plans to go with rookie sensation Michael Wacha.

The Cardinals are hoping the repeat the feat of 2011, when they came back to win the Series after falling behind 3-2 to the Texas Rangers.

"The guys know what we have to do," St. Louis manager Mike Matheny said after Game Five. "They have to lock arms, trust each other and play the game the right way. Most of it is going to be the mentality of not buying into any kind of stats, any kind of predictions, any kind of odds. And go out and play the game." EFE
