Whereas the Astros open a series against the Mariners at home this evening, there are some other games of minor importance to the Astros' fleeting playoff hopes:
Indians @ Tigers, 6:10pm Central. Cleveland is 13-2 against Detroit this season. Detroit is 1.5 games up on the Astros.
Yankees @ Blue Jays, 6:07pm Central. Toronto is 1.5 games up in the WC1 spot, 4.5 up on the Astros in the standings, so this one doesn't matter all that much. The Astros would need to go 6-0 and the Blue Jays 1-5.
Baltimore is off today, for some reason.
