Switch Hitter vs. Switch Pitcher

Switch-hitter comes up. He was practicing swinging left handed and came up to the box that way. Then Venditte switched his glove (custom made with 6 fingers) and the batter also switched. This went on a couple times until the umpires stopped it. After about a 10 minute delay with both managers and the umpires trying to figure it out, they seemed to make the batter pick a box (right-handed), then Venditte switched to pitch right-handed. He schooled the batter for a strikeout, who was less than thrilled.
