Mariners at Astros

The Houston Astros once were 11 games below .500 and now are intermingled with Toronto and Boston near the top of the American League wild-card standings. Houston is a torrid 28-11 since bottoming out and looks to complete a three-game sweep of the visiting Seattle Mariners on Wednesday.

The Astros (45-39), who were postseason participants last season, struggled mightily until the tear that also has seen All-Star second baseman Jose Altuve (.352) take over the major league-lead in batting. A .420 hitter in June, Altuve is 3-for-8 in the series for the Astros, who used two-run homers by Colby Rasmus and A.J. Reed as well as a solo blast by Luis Valbuena to post a 5-2 victory on Tuesday. Robinson Cano was Seattle's lone All-Star selection as slugger Nelson Cruz - who hit his 22nd homer on Tuesday - was passed over. The Mariners have scored just three runs while dropping the first two games of the series after registering 31 in a four-game sweep of Baltimore.

LeBlanc has posted a 1.69 ERA in three career appearances (one start) against Houston and has served up a home run to Evan Gattis.

Fiers has found his stride as he is 3-0 with a 1.57 ERA in his last four starts. He blanked the Chicago White Sox on four hits over six innings to win his last outing.
