But don't be celebratin' just yet, mateys! The Mariners be just as troubled in their last 10 games, baggin' a 4-6 record.

If ye be thinkin' ye can predict the outcome of this sad affair, ye can head over to SportsBetting3.com... Bet on this game and ye might just be laughin' all the way to the treasure chest... But don't forget to review the odds below, lest ye be wastin' yer gold on a lost cause!

So gather round, ye landlubbers, for a showdown on the diamond... Will the Astros find their sea legs, or will the Mariners send 'em swimmin' with the fishes?
