Another exciting playoff game in the MLB between the divisional rivals awaits us in the ALDS tilt on Saturday, October 15, so make sure you get the best Astros vs. Mariners betting pick and odds.

Houston and Seattle will play the third of a best-of-five ALDS series at T-Mobile Park, and the teams are even on BookMaker Sportsbook, while the total is set at 7 runs. These AL West rivals have met 19 times this season before this playoff series, and the Astros lead 12-7. Houston also won the first two games of this ALDS series at home.

Astros took a 2-0 lead thanks to Yordan Alvarez again

The Houston Astros got to a commanding 2-0 lead in the ALDS against the divisional foes Seattle Mariners after a couple of tight victories. Following a comeback 8-7 win in Game 1, the Astros came back again to win 4-2 in Game 2. They are traveling to Seattle with hopes of sweeping the Mariners, and the momentum is surely on their side.

Once again, Yordan Alvarez was a hero of that win as he blasted a two-run homer in the 6th inning when the Astros were 2-1 down and it seemed that Seattle controls the game. Kyle Tucker opened the scoring with a solo shot in the 2nd, while Alex Bregman drove in Jeremy Pena for a 4-2 win. Framber Valdez pitched for 5.2 innings and allowed two runs on four hits with six strikeouts and three walks. Hector Neris was credited with a win in his postseason debut, while Ryan Pressly earned the save.

Lance McCullers Jr. (4-2) will start Game 3 of the ALDS against Seattle on Saturday. The 29-year-old right-hander started eight games this year and owns a rock-solid 2.27 ERA, 1.24 WHIP, and 50/22 K/BB ratio over 47.2 innings of work.

Mariners dropped the lead again and now are 0-2

The Seattle Mariners didn’t have luck in the first two games of this ALDS against the Houston Astros. In both games, they were up late, but dropped the lead and left the Minute Maid Park empty-handed. Seattle is now playing with its back up against the wall, and another loss on Saturday will mean elimination from the playoffs.

The Mariners came up strong in the 4th inning of Game 2 after trailing 1-0 to score two runs through Carlos Santana and Dylan Moore, but that was all from Seattle’s offense in this one. The Mariners had only five hits and not a single individual with a multi-hit display. Luis Castillo took a loss despite pitching well across 7.0 innings, surrendering three runs on five hits with seven strikeouts and no walks.

George Kirby (8-5) will be on the mound for the Mariners in Game 2 of the ALDS against Houston on Saturday. The 24-year-old right-hander started 25 games this season and has a 3.39 ERA, 1.21 WHIP, and 133/22 K/BB ratio over 130.0 innings of work.



  • 13-3 in the last 16 road games
  • 21-8 in the last 29 Divisional Playoff games
  • 5-2 in the last seven road games vs. a right-handed starter


  • 1-6 in the last seven games following an off day

Houston Astros vs. Seattle Mariners Pick

Lance McCullers Jr. didn’t allow more than two runs in each of his previous six starts and has good career numbers against the Mariners’ batters, even though he didn’t face them this year. McCullers Jr. allows a .229 BA and didn’t surrender a single home run in 96 at-bats. On the other hand, I don’t like the fact that Seattle turned to a rookie pitcher to start a crucial playoff game, and I believe that is going to come back and bite them. While McCullers had postseason experience (nine starts), George Kirby will start for the first time in the playoffs, and that is Houston’s advantage here.

Pick: Take the Astros to win (-105)

The Total

After a high-scoring affair in the opening game of the series, we saw six runs in Game 2, and I expect a similar scenario on Saturday. Although I don’t trust Kirby much, he shouldn’t allow more than two or three runs in five-six innings of work. I expect more from McCullers, who is experienced enough to handle the pressure. Under is 6-0 in McCullers’ last six starts vs. American League West opponents, while Under is 4-0-1 in Kirby’s previous five home starts. Also, Under is 5-1 in the last six H2H meetings in Seattle.

Pick: Go Under 7 runs (-110)
