User: When was the last time the Cubs won the World Series
Assistant: The Chicago Cubs last won the World Series in 2016.  They defeated the Cleveland Indians, now referred to as the Cleveland Guardians, in 7 games.  It was a memorable World Series for Chicago considering the Cubs did not play in a World Series for 71 years.  The 7th game was very close as the Cubs blew a 3 run lead in the 8th, leading to extra innings.  Ultimately winning the series in 10 with the last out being a ground ball to a smiling Kris Bryant who threw to Anthony Rizzo for the last out.
