The current betting odds have the Mariners listed as a slight favorite in this game according to Draftkings Sportsbook. The Marlins have looked good in their games this season with their 49-42 record overall which has them right in the middle of the NL East. They have looked great in their own ballpark too with their 28-17 home record this season. Meanwhile, the Mariners have looked good in their games this season with their 47-44 record overall which has them right at the top of the AL West. They haven't been a great road team though with their 20-24 road record this year. The Marlins have been rolling lately and they are 7-3 in their last 10 games now, but the Mariners are 6-4 in their last 10 games and have been getting hot too. The Mariners are going with Kirby in this one and he has looked good this season. He is 7-7 with a 3.81 ERA and he has been a solid starter for them this year. He only gave up 2 earned runs in his last start and his team has been having success with him lately, winning 2 games in a row now with him starting. The Marlins have been putting up runs lately, but their pitching hasn't been great as they are dealing with injuries and have some holes in their starting rotation. Their bullpen has also been giving up a lot of runs lately and they aren't going to have a solid starter here to go deep into this game for them. The Mariners can take advantage of this pitching matchup and they are going to be motivated to stay on the right track now that they are leading the AL West again. The best way to place a bet here is on the Mariners to win this game.

“He just kept doing what he does. He and [catcher Mitch Garver] had a great gameplan again today, using his fastballs. He went to the curveball early, got some swing-and-miss on that and threw some sweepers, but really it was the fastballs. They were being aggressive and playing into what he needed to do, which is make outs.” - Dan Wilson after his team’s win against the Blue Jays in their game on Sunday. 

“Us looking to play beyond the regular season, Eury's going to be an important part of that. He had it really going today, and I totally get it; and there was a part of my heartstrings pulling at his opportunity to keep on going, but I think I have to think about Eury, one, and our organization, our team, and what's best moving forward to give us a chance to continue to win games. So [I] made more of a calculated decision with where he was with the pitch count to take him out.” - Clayton McCullough after his team’s win against the A’s in their game on Sunday.
