Seattle Mariners vs. Oakland Athletics Pick – MLB June 21, 2022

The Seattle Mariners and Oakland Athletics are at the Coliseum for three games in Oakland. They will open things up with Marco Gonzales and James Kaprielian on the mound on Tuesday night.

The Mariners are coming off three tough games against the Angels. They lost three straight with no runs scored in their last two attempts. It was a five-game series with a doubleheader on Saturday.

The Mariners won a 8-1 game on Friday night, though this was their only win of the series. It was a forgettable series at home in Seattle.

Seattle had an 11-game homestand and was only able to win three games. That’s how a team can put their season in a dumpster fire. The Mariners are going into tonight at 29-39 and 13 games behind the Astros for the lead in the AL West.

This is completely predictable for the Mariners.

They overpaid for another player and aren’t getting the desired results. I think we’ve seen this before in Seattle. Throwing money at one expensive player isn’t how success is made.

Robbie Ray hasn’t been living up to his contract, though he did show recent signs of turning things around. Regardless, the Mariners aren’t threatening in the AL West even if he does revert to his Cy Young shape.

James Kaprielean was expected to be a focal point of the A’s rotation this season, but he’s fallen well short. Gonzales will get the go on the road for the Mariners.

Mariners vs. Athletics Prediction:

James Kaprielian has been a mess for the Athletics this season. That’s putting it lightly, as Kaprielian has failed horribly in a season that was expected to be a big year for him.

He recorded an ERA of 7.36 and in two games in his first season in 2020. Kaprielian returned the following season and held his own with an ERA of 4.07 and a 1.22 WHIP. There were big expectations for Kaprielian to elevate his game and develop into a dangerous starter this season.

He’s regressed hard, though, and is trying to fix things in the middle of the season.

Kaprielian has talent, and I’m not writing him off for the future, but more is being asked of him. A lot more. He’s going into tonight with an ERA of 6.31 and a 1.50 WHIP through 42 innings of work.

Kaprielian hasn’t shown signs of improving. He has notched a 7.07 ERA and 1.79 WHIP in his previous three starts.

The Coliseum has been a major trouble spot for him. This is like the rest of the pitching staff and team. Kaprielian isn’t exclusive to pitching poorly at home in Oakland.

He’s entering tonight with a 7.41 ERA and 1.47 WHIP at the Coliseum.

He needs to settle down, but it’s probably going to require an offseason for him to tweak his delivery. The Mariners have been cold lately, though they have had success versus Kaprielian.

  • OVER is 13-3 in their previous 16 games versus a team with a winning percentage below 40%
  • OVER is 10-3 in their previous 13 games on the road
  • OVER is 8-3 in their previous 11 games versus a right-handed starter


  • Record (Last 10): 3-7
  • 1-5 overall in their previous six games versus a team with a losing record
  • 6-21 overall in their previous 27 games as an underdog at home
  • 4-11 overall in their previous 15 games on a Tuesday
  • 1-4 overall in their previous five gmaes after their opponent scores 2 or fewer runs
  • OVER is 8-2-1 in their previous 11 games versus a starter with a WHIP worse than 1.30

  • The Mariners are hitting .320 with a .379 OBP in 44 at-bats against Kaprielian in his career. They’ve recorded 8 RBIs during that time with success scoring runs.

    The Mariners make sense tonight, but Marco Gonzales is always a mixed bag.

    Gonzales has posted an ERA of 3.41 and a 1.31 WHIP. He goes into this start with an ERA of 3.50 and a 1.50 WHIP on the road.

    The A’s haven’t been bad against Gonzales, with 3 home runs and 12 RBIs in 141 at-bats.

    Seattle doesn’t have the best bullpen in the majors, with an ERA of 4.18 and a 1.17 WHIP. Even if they don’t hold up, the Mariners should have success versus Kaprielian, and a bullpen even worse than the Mariners with a 4.35 ERA and 1.42 WHIP.

    The A’s pitching staff has not been reliable at home, as they own a team ERA of 4.49 and 1.35 WHIP. The Mariners look like the play, but I’m not interested in laying -150 on the road in this spot. The OVER has a better price and probably gets there in a 6-4 final at the Coliseum. The total keeps rising for a reason.
