The Oakland Athletics (11-11) head to the Pacific Northwest this Monday, April 20, to face the Seattle Mariners (10-13) in a critical early-season AL West series. Oakland enters the contest surprisingly atop the division standings, looking to maintain their momentum on the road. The Mariners return home to T-Mobile Park where they have been formidable, boasting a 9-5 record in front of their home fans.

Oakland’s offense has been ignited by catcher Shea Langeliers, who leads the club with 6 home runs and a .310 average. He is joined by veteran Max Muncy and rookie Nick Kurtz in a lineup that has proven dangerous when hitting for power. Seattle counters with a balanced attack led by Luke Raley and Randy Arozarena, the latter of whom has been a consistent multi-hit threat. Catch every pitch and stolen base live on Fubo.

The pitching duel features a battle of young right-handers. The Athletics turn to J.T. Ginn (0-0), who has been solid with a 3.31 ERA through his initial outings.
