Who's winning the Houston Astros vs. Seattle Mariners series?

The Seattle Mariners have already won the series by sweeping the first two games, but today’s game still carries important implications for division leadership and the Wild Card race. The Astros currently lead the AL West with a 56–42 record, but the Seattle Mariners are catching up, sitting at 53–45, and with enough momentum, could sneak into a Wild Card spot. Seattle has a lot of steam right now, and could be tough to slow down, but if there's one thing anyone could bet on, Houston's not going down without a fight.
