distracted batter

[kchamp]

Situation: Starting pitcher has pitched to 2 batters with a wristband of school colors on her pitching arm. Before the first pitch to the 3rd batter, the batter complains about the wristband being a distraction. Here's the question: If the defense complains of a distraction, does it become manditory for the umpire to have the wristband removed, or is it left to the judgment of the umpire if it is indead a distraction or not?

Thanks guys
