Lifeless, listless and about to be facing an elimination game, the Yankees discovered a path back into the American League Championship Series. It came by opening the gate to the Houston Astros’ bullpen.

After being held to one hit for the first six innings — and a bloop single at that — the Yankees tore through the Astros’ wobbly bullpen and rallied for a 6-4 victory that got the new Yankee Stadium rocking like the old one and evened the series at two games apiece.

If the Yankees headed home Tuesday night carrying a satchel of momentum, the shaken Astros at least had the comfort of knowing that Dallas Keuchel — who has shut out the Yankees in 13 playoff innings — will be on the mound against Masahiro Tanaka in Game 5 on Wednesday.

“The series wasn’t over after two games,” Astros Manager A. J. Hinch said after his team lost its second game in a row. “It’s certainly not over after four.”
