HOUSTON — Carlos Correa paused a few seconds at the plate and tapped the spot on his wrist where a watch would be. “It’s my time!” the Houston Astros shortstop screamed. That it is. And if his time with the Astros runs out at the end of this season, the star shortstop sure is making this an October to remember. Correa hit a tiebreaking home run in the seventh inning, hollering toward his dugout before beginning his trot around the bases and propelling the Astros over the Boston Red Sox 5-4 Friday night in the AL Championship Series opener. Correa teamed with Jose Altuve to do just enough to overcome the heroics of Kiké Hernández, who starred with his bat and glove for the wild-card Red Sox. “I’ve been watching them for years, and it’s a pleasure to be watching them up close and personal,” manager Dusty Baker said.
