As Senator of Illinois and as Commander-in-Chief he is all about the White Sox, but it turns out the President of the United States is an A's fan at heart.
He said because he grew up in Hawaii, he decided that Oakland was close enough to call that his home team.
It probably didn't hurt that the A's won back-to-back-to-back World Series in 1972, 1973 and 1974.
Mr. Obama was at the formidable age of 11, 12 and 13 for those big seasons.
"I did not become a Sox fan until I moved to Chicago," he said.
