The current betting odds have the Mariners listed as a slight underdog in this game according to Draftkings Sportsbook. The Mariners have looked really good in their games this season with their 67-54 record overall which has them right near the top of the AL West. They haven't been a bad road team either with their 30-29 road record this season. Meanwhile, the Mets have looked good in their games this season with their 64-56 record overall which has them right near the top of the NL East. They have also looked great in their own ballpark this year with their 39-22 home record. They have looked terrible lately though, going 2-8 in their last 10 games as they have been in a big slump while the Mariners are 8-2 in their last 10 and have been red hot. The Mariners also have the better pitching matchup in this one and they can take advantage of that. The Mariners are going with Castillo in this one and he has looked great this season. He is 8-6 with a 3.19 ERA and he hasn't been giving up many runs lately. He is coming off another good start in which he gave up 2 earned runs and the team has won 2 of their last 3 games with him starting too. The Mets are going with Manaea in this one and he hasn't looked great this season. He is 1-1 with a 4.33 ERA and the team hasn't had a ton of success with him. He is coming off a bad start in which he gave up 4 earned runs and the team has lost 3 games in a row now with him starting. All signs point to the Mariners to take advantage of a slumping Mets team. The best way to place a bet here is on the Mariners to win this game.

“It’s a tie game at that point, and I thought they barrelled up a couple balls. And Gabe has been so good for us in those situations. They were just able to get one up off the wall and get the two runs there. Those are the tough decisions, and we thought at the moment that was the right one.” - Dan Wilson after his team’s loss against the Orioles in their game on Wednesday.

"The pitching coaches are digging deep to make sure we’re not missing anything of what’s going on here.” - Carlos Mendoza after his team’s loss against the Braves in their game on Wednesday.
