This might be a stretch.... Looked up Atlanta Braves rosters 1981-2009. Here's what I got; Players for the Braves with the name Mark and a vertical line to start their last names; Mark Lemke, Mark Eichhorn, Mark DeRosa, and Mark Kotsay. I ruled out Mark Grant, Wohlers, Whiten, and Teixiera.

None of these players wore the number 4 while a Brave. However Kotsay did wear #4 earlier in his career, in Atlanta the number was assigned to Omar Infante in 2008. Kotsay did hit for the cycle that year (August 14). Don't know if Infante may have been trying to get his bat going by borrowing a teammates who had just hit for the cycle, or what. Impossible to verify.... rampant speculation.... completely irresponsible to suggest anything.. What the hell!
