Mets pitcher Jonathon Niese left his final start of the season with an elevated heart rate, a condition he has dealt with before, and the Houston Astros rallied Friday night against reliever Carlos Torres for a 3-1 victory over New York.

Jose Altuve, closing in on the American League batting title, hit a tying single in a three-run sixth inning. Chris Carter and Robbie Grossman doubled off Torres, and Matt Dominguez capped the outburst with an RBI single.

Kevin Chapman (2-0) got two outs, Tony Sipp tossed two perfect innings and the Astros snapped a three-game skid by winning for the third time in 10 games. Chad Qualls worked a 1-2-3 ninth for his 19th save.
