The current betting odds have the Mariners listed as a slight favorite in this game according to Draftkings Sportsbook. The Mariners have looked good in their games this season with their 34-32 record overall which has them right at the top of the AL West. They haven't been a great road team though with their 15-16 road record this year. Meanwhile, the Orioles haven't looked great in their games this season with their 31-35 record overall which has them right near the bottom of the AL East. They have looked a lot better in their own ballpark though with their 19-15 home record this season. The Orioles have had a lot of trouble all season and they are only 5-5 in their last 10 games, giving up a ton of runs too. The Mariners had a terrible start to the season, but they have turned things around and are now 7-3 in their last 10 games, leading their division too. Both offenses have looked pretty good lately, but the Mariners do have the better pitching matchup in this one and they can take advantage of that. The Mariners are going with Gilbert in this one and he has looked good this season. He is 4-4 with a 3.79 ERA and his team has had a ton of success with him this year. He did give up 3 earned runs in his last start, but he has looked a lot better lately and the team has won 3 games in a row now with him starting. The Orioles are going with Rogers in this one and he hasn't looked great this season. He is 3-6 with a 6.29 ERA and his team has had a lot of trouble with him this year. They have lost 7 of their last 8 games with him starting and he has been giving up a ton of runs all season. He is off a great start in which he only gave up 1 earned run, but that hasn't been a common theme for him and the Mariners are going to put up runs with their offense being really hot over the last week. Look for the Mariners to bounce back from that series loss to the Tigers and get themselves back on track in this series. The best way to place a bet here is on the Mariners to win this game.

"I thought [Castillo] had things well under control. He really kept [the Tigers] pretty quiet for the time he was out there and allowed our offense to get going a little bit.” - Dan Wilson on Luis Castillo after his team’s loss against the Tigers in their game on Sunday.

“Definitely frustrating, especially when you put up four runs against a really good pitcher in [Toronto starter] Kevin Gausman. That’s the frustrating part.” - Craig Albernaz after his team’s loss against the Blue Jays in their game on Sunday.
