The Washington Nationals celebrate after winning Game 7 of the World Series, 6-2, over the Houston Astros Wednesday night.

HOUSTON — Howie Kendrick sure has a knack for the dramatic.

At 36 — nine years removed from is only All-Star appearance — he hit a go-ahead, two-run homer off Will Harris in the seventh inning that lifted the Washington Nationals over the Houston Astros 6-2 Wednesday night in Game 7 for his team’s first World Series title.

Steady-handed and battle-tested, Kendrick came through at the biggest moments of the Nationals’ October run.

His grand slam against Joe Kelly broke a 10th-inning tie in the decisive Game 5 of the Division Series, giving the Nationals a 7-3 win — just the second extra-inning slam in postseason history.

He hit .333 with four doubles in the NLCS as well.
