Seattle Mariners vs. Miami Marlins: betting odds and predictions for Jun 21

Publish Date: 06/21/2024
Fact checked by: Allan Howe

The Seattle Mariners are coming off a series defeat to the Cleveland Guardians when they head down to South Florida to kick off their three-game series with the Miami Marlins.

The Mariners who are still at the top of the AL West will be looking to take this series from the Marlins before they head back home with some momentum going into the new week.

Meanwhile, the Miami Marlins, have defied the odds in their two-game winning streak with back-to-back walk-off wins against the St. Louis Cardinals which has now given the Marlins 7 walk-off wins this season which is the most in a single season in MLB history.

They will be looking to possibly make it three walk-off victories in a row when they play host to the visiting Seattle Mariners on Friday night.

Seattle Mariners

Seattle Mariners (44-33) came into this series with wins in seven out of their last 10 games but have lost back-to-back matchups against the Cleveland Guardians. They lost two of three from the Guardians losing their first series in the last two weeks.

However, the Mariners now get a chance to right their wrongs when they take on the worst team in the National League the Miami Marlins.

The Mariners certainly haven't been struggling at the plate as they've been averaging 4.8 runs and 1.4 home runs per game over their last 5 games. It's been their dreadful pitching that can't keep them off the scoreboard.

  • The Mariners' pitching staff has given up 14 runs in their two losses to the Guardians and are hoping for some solid pitching at the start of this series with the Marlins to get them back on track.

  • The Mariners will be sending George Kirby to the mound who despite his 6-5 record and 3.54 ERA has been dominant over his last 5 starts.
  • Over his last 5 starts, Kirby has a 4-1 record, a 1.80 ERA with 30 strikeouts in 30 innings.
  • He has now only given up four runs over his last four games while he most recently blanked the Texas Rangers giving up 0 runs on 3 hits while striking out 6 in 6 innings.

The Mariners will be set to take on lefty Trevor Rogers in the first game of this series this Friday night. Rogers has been a former shell of himself this season and will be facing the daunting task of going up against a tough right-handed lineup.

It's up to the Mariners to get after Rogers early in this game giving Kirby enough run support as he shuts down this Miami Marlins team as they get back on track and kick off this series on the road with a win.

Miami Marlins

Miami Marlins (25-49) are dead last in the Majors with just 25 wins in their 74 games on the season. However, the Marlins were able to string together back-to-back walk-off victories against St. Louis taking two of three and winning a series for the first time in quite a while.

The Marlins now have 7 come-from-behind walk-off wins this season which would make it the most in MLB history in a single season.

  • The Marlins bats have come alive in their series with the Cardinals where they scored 19 runs but it was their pitching staff that allowed 18 runs over that span.

They will look to continue their hot bats in tonight's matchup when the Mariners come to town.

  • Heading out to the mound for the Marlins is Trevor Rogers who despite having a rough season with just a 1-8 record and a 5.09 ERA is coming off of one of his better outings against the Washington Nationals.
  • In that game, he gave up two runs on six hits and no walks with three strikeouts in 7 innings.

If Rogers can continue this pace against the Mariners who strike out the most out of any team in the majors they have a great chance at extending their winning streak to three in a row as long the hot bats of the Marlins keep their momentum going into this home series.

FINAL MARINERS-MARLINS PICK & PREDICTION

The Seattle Mariners are looking to get back on track after hitting a rough patch over their last 2 games meanwhile, the Marlins will be looking to continue their winning ways at home as they attempt to take game 1 in this series against the Mariners.

Both teams send surging pitchers George Kirby and Trevor Rogers to the mound who have been pitching well as of late.

All signs point to this matchup being a pitcher's duel with runs being very limited.

  • While it is tough to take a side here, especially on a team that is struggling like the Marlins, the Mariners should be able to get back on track against the bottom-feeding Miami Marlins and take game 1 heading into this weekend's matchup.

FINAL MARINERS-MARLINS PICK & PREDICTION: SEATTLE MARINERS (-166)
