That's... weird

I was watching the Cubs/Cardinals game this afternoon. In the Cubs' big fourth inning, Mike Fontenot came up with two men on and the Cubs leading 3-0. Kyle Lohse threw a pitch that went for a ball. Suddenly, in the top of the screen, the graphic flashed "Home Run Cubs" and the score changed to 6-0. After a couple seconds, "Home Run Cubs" vanished and the score returned to 3-0.

Five seconds later, Lohse threw another pitch; Fontenot hit a home run.

I'm sure someone had just hit a wrong button, but is that weird or what?
