The Astros head to Denver after a rather uplifting series against the Mariners that featured two straight walkoff wins and putting to bed a pretty awful stretch of baseball. Though they lost the first series against the Pirates, the team did at least continue its winning ways at home with a successful 4-2 homestand. It was also quite helpful to have a series against the Mariners, a team that Houston has traditionally used as a launching pad for winning streaks and good stretches of baseball. They were also able to make up some ground in the division, gaining a couple of games on the Rangers.
