What is modern postseason baseball without controversy involving replay review? In the bottom of the first inning of ALCS Game 4, with the Astros trailing the Red Sox 2-0, José Altuve slapped a Rick Porcello fastball to deep right field. Deep enough for a game-tying two-run home run, in fact. Right fielder Mookie Betts tracked the ball and leaped at the last minute to try to snag the ball, but came up a little short. The ball at first glance appeared to bounce off of a fan’s hand and back onto the field. Right field umpire Joe West initially ruled fan interference, meaning Altuve was out. The Astros challenged and the ruling was upheld, controversially.
Major League Baseball offered clarification on the ruling. Per Joel Sherman of the New York Post:
That was a huge swing for both teams as the game would have been tied otherwise. The Astros did push across a run later, in the bottom of the second, and the Red Sox added a run in the third, so the game is 3-1 as of this writing.
