I'm going to stick with the baseball clue, since Johnny Neun and George Burns are the only first basemen to turn an unassisted triple play.

I think Pi refers to the (Pi)tchers mound, a circular object in the center of the baseball diamond.

I think the Amethyst colored glasses refer to an optical filter.

So, I think there will be an object, detectable by the IR sensor, between "first base" (starting point for the robot) and the center of the field.

I like the Blue+Red = Purple concept, although I do not immediately see how this will play out. Also, what will be the FIRST equivalent of the unassisted triple play? Those items, plus Car Nack's prediction, lead me to believe that alliances, if there are alliances, are not going to be what we have seen in the past.

BTW, the Championship Eligibility criteria still list 3 Regional Champions per Event.

Amethyst is February's birthstone.
