Dusty Baker, Cubs manager
Those who saw the Cubs-Marlins game probably saw the poor kid who touched the foul ball when it looked as if it could have been caught by Moises Alou for the second out for the Cubs in the 8th inning. After that play, the Marlins scored 8 runs that inning to take an 8-3 lead and eventually won the game.
Afterwards, Baker was asked about why the Cubs had lost the game.
Baker named the kid as one of the main reasons for their lost and speculated that the kid was probably a Marlins fan. Besides the sore losership in blaming a fan for losing, he could have made life a little easier for the kid, who probably can't even go to school tomorrow for fears of getting beat up by classmates. If Baker had told Cubs fans that the team should be responsible for their losing and that the fans shouldn't blame the kid, then maybe the kid wouldn't have to fear for his life when he wakes up tomorrow. Instead, Baker further fanned the flames, and I hate to think what'd happen if the Cubs lose tomorrow.
UPDATE I should also add that if the FOX commentators thought that the kid didn't do anything wrong, they should have told the producers in the truck not to show the kid every 5 minutes.
