Cardinals vs Mariners MLB Spread & Game Preview

Written by on July 3, 2019

The teams who are in the hunt for a playoff spot will all routinely tell you that they are simply taking things one series at a time. The reality, though, is that they probably do the same as us fans, which is to look down the schedule and pick out games and series that they think they can win. In that list, there are probably a few teams that they have already been dominant against and who they would expect to beat over the course of a 3- or 4-game series, but there are also going to be some question marks. Very often, those tend to be the interleague games, as it’s tough to really get a bead on teams that you don’t face very often.

While some teams thrive in interleague play, others falter. We have one such series going at the moment, and given the outcome of the opening game, it’s looking as though the Cardinals are going to have their hands full with the floundering Seattle Mariners. Despite losing the opener, the St. Louis Cardinals are favored by 1 ½ on Wednesday, with the run total set at 9.

Indians vs Royals MLB Odds & Pick for Wednesday Night

Why bet on the St. Louis Cardinals?

It has been a bit of a frustrating season for the St. Louis Cardinals, which is also something that can be said for the other 4 teams in the NL Central. Not one of those teams has been able to go on a run of consistent form that would put them in the driving seat, which is why we have just 5 ½ games separating first from last in the division.

The Cardinals are in the middle of the pack, sitting at 41-42 on the season, which has them 3 ½ games out of the top spot, which is currently being held by the Milwaukee Brewers. It has been a rough run of form for St. Louis of late, as they have now lost 3 in a row, including a 5-4 loss to Seattle in the opening game of this series, as well as having just 3 wins in their last 10 games. In interleague play, they are 4-7. The Cardinals will have Adam Wainwright (5-7, 4.35 ERA) on the mound.

Why bet on the Seattle Mariners?

Despite the fact that the Seattle Mariners have crashed hard after a great start to the season, they are still not an easy team to face. On any given night, the Mariners bats can go off in a big way, with shootout style games very often the order of business for this team. It is their ability to score runs that makes them such a threat despite being just 38-51 on the season.Cardinals vs Mariners is going to be a close one.

They have not had a lot of joy playing at home, going 18-25 in their own ballpark, while also sitting at 3-5 overall in interleague play after their win over the Cardinals on Tuesday night. They have been a decent bet as a home dog, going 15-11 ATS in those games. It will be Mike Leake (7-7, 4.63 ERA) who gets the start in this one.

  • Runs: 5.18

The Cardinals are an infuriating team in terms of wagering, as they never seem to be able to do what you expect of them. I am playing it safe here and taking the Mariners to cover.
