Astros, Mariners Look to Rebound From Lost Weekend

Astros, Mariners Look to Rebound From Lost Weekend

Both Houston and Seattle have spent time on top of the American League West standings. However, heading into the second to last series of the regular season, they are both behind Texas and fighting it out for the final Wild-Card spot in the American League. According to our MLB odds, the Mariners are favored in the opening game of this pivotal series.

Among American League teams, only the Baltimore Orioles have more road wins this season than the Astros, while Seattle is 41-33 at home. When it comes to the run line totals, Seattle is just 30-44 as the home team, with Houston 44-31 on the road.

Both teams come into this series having lost three games in a row.

Seattle has won eight of 10 games against the Astros this season and won the first three series between the division rivals.

When looking at MLB predictions, the Mariners are priced at -121 in Monday’s series opener, with a total set at 7.

When looking at MLB playoff odds, Houston is priced at -115 and Seattle is at -120 to make the postseason.

Starting Pitchers

  • Monday: Justin Verlander (11-8, 3.44 ERA) vs. Luis Castillo (14-7, 3.06)
  • Tuesday: Cristian Javier (9-4, 4.64) vs. George Kirby (11-10, 3.58)
  • Wednesday: Framber Valdez (12-11, 3.39) vs. Bryce Miller (8-6, 4.17)


Astros: Starting Pitchers Need to Step Up

The starting pitching has had some issues for the Astros in September, with a 5-11 record and a 5.51 ERA. The 25 home runs allowed in 21 games have been just one of the issues.

Valdez has the best ERA (3.42) among Houston starters, with Valdez and Javier limiting opponents to a .213 batting average in September. Keep that in mind when looking at the best MLB parlays for today.

All three starters in this series have pitched in high-profile games before, which could play a role in how this series shakes out.

Mariners: Seattle Hitters Coming Up Empty

Seattle picked the worst time to go cold at the plate.

Philadelphia is the only team in playoff position with a lower batting average in September than the Mariners’ mark of .239.

The .310 on-base percentage is the worst among the American League teams still in playoff contention. However, Seattle did have six extra-base hits in Sunday’s loss to Texas.

Eugenio Suarez, Ty France, Dominic Canzone, Mike Ford, Dylan Moore and Josh Rojas are all hitting under .250.

Seattle is hitting .287 with 11 home runs against the Astros, so perhaps seeing Houston pitching is what Seattle needs to get going.

Astros vs Seattle Head-to-Head

MLB betting on this series total is split, with 10 games this season seeing five go under the total and five finish over.

Seattle went into Houston and took all three games in the most recent series from Aug. 18-20. Can Houston return the favor?

Over the last five meetings, there have been two one-run games and two others decided by two runs.

Teoscar Hernandez is hitting .343 against the Astros, while Eugenio Suarez leads Seattle with three home runs and seven RBIs versus the Astros. For Houston, Yordan Alvarez is batting .318 and Kyle Tucker has a .304 average. When looking at MLB parlays for Sept. 25, take a look at the +115 odds for Alvarez and +145 odds for Suarez to score a run.

Astros vs Mariners Series Betting Lines

MLB Betting Predictions: Astros-Mariners

Neither team is coming into this series bursting with confidence. One of the questions is how Kirby and Miller will handle things in their starts against Houston pitchers with much more experience in playoff races.

There’s not much to separate these two teams, which makes Seattle’s impressive results against Houston so surprising. Can the Astros figure out a way to take their first series against the Mariners?

Michael Brantley is questionable heading into the series for Houston. However, Brantley has only played in 12 games this season, so this is nothing new. Catcher Tom Murphy is on the injured list for the Mariners.

The Mariners are 39-27 and the Astros 35-30 since the All-Star Game. The Mariners have the second-best team ERA among American League teams during that stretch, but it still might make more sense to place an online bet on the Astros in this series.
