Before Friday, the Cubs had won every series opener that they had played at Wrigley Field. On the last homestand, they finally broke the streak of losing every Sunday. Do you know what those things are? Totally arbitrary outcomes. There is no reason to believe either thing will continue. Consider this a corollary to good teams don’t win close games. They win blowouts. It’s an oh, duh thing.
The Cubs have won a lot of series openers, particularly at Wrigley Field, because they’ve won a huge percentage of their games. If this continues, their splits will be good in every situation.
