Astros vs. Mariners Key Players to Watch

Houston Astros

Jose Altuve: The Astros' second baseman isn't getting the credit he deserves for how well he's played this season. He leads the team in batting average at .305 and he's also the best on the Astros in terms of WAR at +2.9.

Seattle Mariners

George Kirby: If the Mariners want to keep winning games, they better hope their pitchers, like George Kirby, will keep playing at an elite level. Their offense has struggled but they have the best team ERA in the American League at 3.46. It starts with Kirby tonight.

Astros vs. Mariners Prediction and Pick

My favorite bet of the night as the Astros as underdogs in Seattle. I broke down why in today's edition of Walk Off Wagers.

"Last night's 3-0 decision in favor of the Houston Astros may be a sign of things to come against the Seattle Mariners. They've managed to continue winning games despite having one of the worst offenses in baseball. They're 27th in OPS at .672 dating back to June 1 while batting just .213, the worst mark in baseball in that time frame.

"Houston, on the other hand, ranks inside the top 10 in both of those stats.

"I'm surprised we're able to get the Astros at plus-money in this spot with Framber Valdez (3.66 ERA) on the mound."
