Before the question is asked about the 'patch' on Carlos Lee's uniform:

The two Carlos Lee photos in the above post are from the actual game on June 8, 2001 and were taken as he hit the GW GS.

The uniform patch on his right sleeve is the 'The American League 100 Seasons Charter Member Patch' which was worn during the 2001 season by the 4 charter member teams (White Sox, Red Sox, Tigers & Indians) of the American League.  The other 10 AL teams wore a slighly different version of the patch that didn't include the words 'charter member'.
