Miami Marlins Betting Preview

The Miami Marlins (12-14, 4-6 Away) beat the Cincinnati Reds in two of three games at home, opened this series in Seattle with an 8-4 victory, and then were destroyed in Game 2. Not only that the Marlins fail to score a single run for the second time this season, but they also allowed a season-high 14 runs in a loss. Connor Gillispie took the loss after allowing seven runs on six hits with two strikeouts and two walks in 2.0 innings.

The Seattle Mariners (15-12, 9-6 Home) returned home from a three-series road trip during which they beat the Reds, Blue Jays, and Red Sox. After losing Game 1 of the series against the Marlins, the Mariners responded with a massive 14-0 victory. That’s the first time this year the M’s kept the opponents off the scoreboard, while it was also their highest-scoring game of the campaign. Ben Williamson led the team with four RBI, while Luis Castillo got the win after allowing no runs on one hit with five strikeouts and two walks over 6.0 innings of work.

This season, the Mariners average 4.50 runs per game (10th in the MLB) on a .228/.326/.390 slash line. Regarding pitching, the Mariners’ staff has a 3.85 ERA (12th) and 1.33 WHIP (18th). Jorge Polanco leads the Mariners with a .354 batting average, seven home runs, and 18 RBI this season.

The projected starting pitcher for the Mariners is Logan Evans, who is getting his first start in the majors in what will be his MLB debut.

Marlins vs Mariners Prediction

The teams have traded wins in the last few years, as each recorded five in the previous ten H2H duels. The Marlins won four of the last six, and I am backing them to stay close and put up a fight in this one, as they will face the rookie on the mound. Max Meyer, on the other hand, has been more than solid so far this season and connected four quality starts, so I expect him to have another one on Sunday. Now, I am not saying that Miami is going to win in Seattle, but the Marlins should at least cover.
