The Seattle Mariners will try to ride the momentum of a dramatic series sweep when they visit the American League West-leading Houston Astros for the first of three games Monday night. After winning their final game before the All-Star break, the Mariners took three in a row at the Chicago White Sox to open their road trip, capped by a 7-6 win in 10 innings Sunday.

Nelson Cruz's solo homer was the difference for Seattle (46-47), which has a chance to get back to .500 for the first time since June 25. Houston's lead over the Mariners in the American League West stands at a very comfortable 16 1/2 games, and it has won seven of 10 meetings between the two. The Astros rode a strong start from Mike Fiers (season-high 11 strikeouts in seven innings) en route to a 5-3 win over Minnesota on Sunday to take two of three. Lance McCullers Jr. will try to duplicate Fiers' performance when he gets the nod in the opener opposite lefty Ariel Miranda.
