Changing jerseys to beat the 103-degree heat, the Dodgers ace with a checkered playoff history delivered a signature performance, pitching Los Angeles past the Houston Astros 3-1 Tuesday night in the World Series opener. Boosted by Justin Turner's tiebreaking, two-run homer in the sixth inning off Dallas Keuchel, Kershaw was in complete control against the highest-scoring team in the majors this season. ''Definitely feels good to say it was the World Series, and it feels good to say we're 1-0,'' Kershaw said.
