The White Sox took to Twitter on Saturday night to congratulate their crosstown rivals on earning their first World Series berth since 1945.
Two days later Jerry Reinsdorf took it a step farther.
The White Sox owner told Chicago Sun-Times' Michael Sneed that he'll be rooting for the Cubs when they begin their series against the Cleveland Indians on Tuesday.
"I think it would be great for Chicago if the Cubs won!
"Cubs fans have suffered enough. They deserve to have a winner. It would be great for the city.
"My White Sox fans won't be happy with me saying this. They'll think I'm a traitor. But that's how I feel."
Reinsdorf may have felt different had his White Sox not hoisted the World Series trophy in 2005. But he understands how Cubs fans feel; when the South Siders won the 2005 World Series it ended an 87-year drought. That was the second longest drought in MLB history, behind only the Cubs and their current 107-year streak.
Perhaps the fact that the Cubs are playing a White Sox AL Central rival in the Indians helps matters.
Either way, Reinsdorf is hoping to see the Cubbies bring home the title for the first time since 1908.
"I have never been a Cubs fan," Reinsdorf said. "But I really do wish them well."
