The Mariners escape Kansas City having secured a series win, barely, and will now face a much tougher team in the Houston Astros, who are healthy now and a much different team than Seattle won a series against in Houston prior to the All-Star Break. Houston will also be bringing the best of their rotation in Cy Young candidate Framber Valdez and a pair of Rookie of the Year candidates in J.P. France and Hunter Brown, while the Mariners will have be throwing their own pair of rookies in Emerson Hancock and Bryce Miller, who takes the ball tonight to face the Astros for a second time in his home state.
