Mine is probably from 2008. The Brewers had acquired CC Sabathia recently, and he was dominating. In his first 4 starts, he had 4 wins and 3 complete games (1 shutout). The Cubs were heading into Milwaukee for a 4 game series and I had tickets to all 4 games with my dad and brother. They were up by one game in the standings.
The Cubs scored 4 runs with CC on the mound and he left the game in the 6th (or 7th? I forget). They ended up winning the game and sweeping the series. I still remember the entire stadium erupting into "Go Cubs Go" at the end of one of the games. Not sure which game it was...oops haha.
