(Chicago, IL) -- The Seattle Mariners will be back home tonight, after seeing a six-run lead evaporate in a 12-inning loss to the Chicago Cubs. Seattle opened their lead on the strength of two-run homers by Nelson Cruz, Robinson Cano, and Dae-Ho Lee. But Chicago earned the win when Jon Lester drove in Jason Heyward with a sacrifice bunt in the 12th. The Mariners will start a four-game series with Boston tonight at Safeco Field.
