Seattle @ Houston preview

Last Meeting ( Jul 1, 2014 ) Seattle 13, Houston 2

The Seattle Mariners have rolled up 23 runs over the first two games of the series and look to complete a three-game road sweep of the Houston Astros on Wednesday afternoon. Seattle racked up season bests in runs scored and hits (18) while rolling to a 13-2 win Tuesday and has won 12 of 16 games to move a season-high eight games above .500. Houston second baseman Jose Altuve had two hits but his franchise mark of stealing at least one base in seven straight games reached an end.

After promoting prized outfielder George Springer and first baseman Jon Singleton earlier this season, outfielder Domingo Santana made his Houston debut in Tuesday’s loss. The 21-year-old Santana, acquired from Philadelphia as part of the package for Hunter Pence in 2011, struggled by striking out three times in four at-bats but figures to get a long look over the second half of the season. Seattle has scored 10 or more runs in back-to-back games for the first time since June 19-20, 2012 – when it split the two games with Arizona – and strives for another hot performance with the bats in the finale.
