The Boston Red Sox are one win away from knocking off the defending World Series champion Houston Astros and booking their ticket to the Fall Classic.

Boston won a heart-stopping Game 4 on Wednesday to take a 3-1 lead in its American League Championship Series with the Astros.

After the game, Red Sox manager Alex Cora noted how tough-minded the Astros are pointing out his team knows it will be difficult to close them out.
