Chicago Cubs second baseman Nico Hoerner hit a walk-off RBI single to lift his team to a 3-2, 10-inning victory over the Seattle Mariners at Wrigley Field on Monday evening. Hoerner's hit drove home pinch-runner Nick Madrigal from third base with the winning run after Madrigal, installed at second base as the extra-innings "ghost runner", previously stole third base to set up his victorious jog home.

Hoerner told the Chicago Sun-Times that he was elated to get the game-winning hit."I was just so happy. What a special thing to experience."Chicago Cubs fans were elated as well. The team held a 2-1 lead into the top of the ninth inning before closer Michael Fulmer blew a save by allowing a game-tying home run to Mariners outfielder Jarred Kelenic. The game went into the 10th innings after the Cubs went quietly in the bottom of the ninth.

Smyly went five innings, allowing just two hits and one earned run while striking out seven. Furthermore, three relievers teamed up to hold the Mariners scoreless before Kelenic's solo homer in the ninth. Keegan Thompson recovered from a shaky start to the top of the 10th inning to emerge unscathed, despite walking two batters to earn the win after Hoerner ended the game in the bottom half of the frame.
