Thursday nights Game 4  of the American League Championship Series is a must win for the Yankees, and they have their best postseason pitcher on the mound. Masahiro Tanaka loves the challenge of winning in the playoffs, and his teammates need him to pitch a gem against the Astros in order to even the series at 2 games apiece. We all know if Houston wins game 4, the series is all but over and the Yankees not reaching World Series would be considered a failed season in the eyes of most Yankee fans.
