CHICAGO -- The Windy City saw plenty of New York on Tuesday, as both the Yankees and the Mets played road games within Chicago's city limits. The Mets may have left town, but the Big Apple was still out in force on Wednesday.

Yankees manager Joe Girardi had a surprise guest visitor in his office at U.S. Cellular Field, welcoming in New York City Mayor Michael Bloomberg for a brief, informal chat.

"We talked baseball," Girardi said. "I'm not much into talking politics. He was just talking about how to handle situations you have, talking about the city and the heartbeat of the city. It was good."

While Bloomberg and Girardi spoke, several protective agents loomed outside in the clubhouse runway. After the meeting was complete, Bloomberg stepped onto the field and signed autographs for several fans, most in Yankees apparel.

Bloomberg is in Chicago to accept an award at the CME Group Center for Innovation. The mayor is being honored for his contributions with his company Bloomberg L.P., which has made a informational impact on the financial markets industry.
