Alex Bregman, Framber Valdez and the Houston Astros are off to a perfect start this postseason.

Taking the formula that won them 106 games in the regular season — strong pitching and hitting home runs — the Astros kept rolling against the New York Yankees.

Bregman connected for an early three-run homer, Valdez threw seven strong innings and the Astros edged the Yankees 3-2 Thursday night to take a 2-0 lead in the AL Championship Series.
