PITTSBURGH (AP) — Framber Valdez pitched seven strong innings, Isaac Paredes homered twice, and the Houston Astros beat the Pittsburgh Pirates 8-2 after a lengthy rain delay. Valdez (6-4) won his fifth straight decision by limiting the Pirates to two runs on five hits with three walks and a season-high 11 strikeouts after waiting out the delay that pushed the start of the game back 3 hours and 22 minutes. Paredes hit his 13th homer of the season leading off the fourth against Mitch Keller (1-8). His 14th, a two-run shot in the ninth, put the game away. Jared Triolo had two hits and scored twice for the Pirates.
