The Phillies were in a tough spot, losing a bunch of games and in desperate need of a victory.
Their ace pitcher Zack Wheeler dominated the Mariners, striking out nine batters and not letting them score at all.
The Phillies' bats came alive, hitting four home runs, including a lucky catch by Brandon Marsh that seemed to turn the tide.
This big win snapped a six-game losing streak and gave the Phillies some much-needed confidence.
