Guardians-Mariners Same Game Parlay Options

After winning their first division title last season, the Mariners are looking to prove that it wasn’t just a one-time fluke and it all begins against a Guardians team that banks on its talented bullpen to stay competitive in every game. Crafty pitcher Bryan Woo, who made his first All-Star appearance last year, will be critical in keeping opposing hitters off balance here as his ability to mix fastballs with sharp breaking pitches makes him extremely tough to cover.

That’s why I am backing the 26-year old Woo to pitch at least five innings here and dictate the tempo early. If there’s one thing I’ve seen from Woo from last season is he really shines when attacking the strike zone early and keeping hitters guessing at every turn. I am pairing that up with an over 1.5 RBI game from Cal Raleigh who has been especially dangerous with runners in scoring position.

Taking all things into account, I’m leaning strongly toward adding the Mariners moneyline to sweeten my Fliff same-game parlay. With the Mariners’ pitching depth and the Guardians inability to generate offense beyond Jose Ramirez, I just think the home squad will prove too much here offensively. It is also worth noting that the Mariners dominated the Guardians 20-8 just recently although that was during Spring Training.
