Key Storylines
- Seattle has stacked wins to draw level atop the AL West, powered by elite power from Cal Raleigh and a hot stretch from Julio Rodríguez.
- Los Angeles recently slugged 12 runs behind Kyle Hendricks in Minnesota, but their run prevention has been volatile all month.
- The season series has nudged Seattle’s way, and recent form magnifies the gap entering Sunday.
Pitching outlook
- George Kirby, RHP, Mariners: 8-7, 4.56 ERA, 1.27 WHIP, 108.2 IP, 106 K. Kirby is a pinpoint strike-thrower facing an Angels lineup that ranks in the bottom tier in OBP. His bat-missing has ticked up recently, and day-game numbers for Seattle support a strong defensive backdrop for him in this game.
- Kyle Hendricks, RHP, Angels: 7-9, 4.58 ERA, 1.27 WHIP, 149.1 IP, 95 K. Hendricks is a command-first righty who just spun seven scoreless innings in a blowout win at Minnesota. But his season-long contact quality remains a concern against Seattle bats that punish mistakes, led by Raleigh and Rodríguez.
Recent team streaks
- The Mariners have won eight games in a row going into this matchup.
- The Angels have dropped three games in a row going into the finale of this series.

Final Thoughts
Seattle owns advantages on the mound and in run prevention, and their current form amplifies those edges. Kirby’s elite strike-throwing should suppress free passes to an Angels lineup that needs traffic on the bases to generate crooked numbers. The Mariners’ middle-of-the-order thunder has a favorable hitting environment against Hendricks’ contact profile. With Seattle thriving in day games and holding the better bullpen at the moment, the path to covering -1.5 is clear if Kirby works into the sixth and hands a lead to the bullpen.
