After 18 long innings, and nearly 6 1/2 hours later, the Houston Astros swept the Seattle Mariners with a 1-0 victory Saturday evening.

Rookie shortstop Jeremy Pena scored the winning home run that ended Seattle’s path to the ALCS.

“These guys, they know not to panic,” Houston manager Dusty Baker told The Associated Press. “They don’t get too excited. They don’t get too down. It means a lot.”

Peña drove a slider from Mariners’ Penn Murfee deep to left-center for the rookie’s first playoff homer, providing the only run in an afternoon full of dominant pitching and empty trips to the plate.
