Key Storylines
Pitching matchup
We are in for a very good pitching matchup in Wednesday’s game. Logan Gilbert and Trevor Rogers are both having strong seasons individually. Rogers has been especially impressive thanks to a 1.44 ERA over 62.1 innings of work. We may not see another 1-0 game on Wednesday, but I think we may not be far off given the strength of the starting pitching here.
Key Players
- Cal Raleigh: Raleigh has 98 RBI for the Mariners this season and will try to get back on track after a poor offensive game from everyone on Tuesday.
- Baltimore Bullpen: The Orioles’ bullpen has a much higher ERA than that of the Mariners. Baltimore’s pen can’t afford to waste anything good that Rogers gives them on the hill early in the game.
Recent team streaks
- The Mariners have won eight games in a row and will look for a ninth straight win on Wednesday.
- Baltimore has dropped three games in a row and is in last place in the AL East.

Final Thoughts
The Mariners are red hot and I think their winning streak will continue in this contest. But my favorite play in the betting markets for this game is for the under to hit. Both starting pitchers have been very good for their respective teams. I think we see a second straight pitcher’s duel between these American League opponents.
