Anyone know what type of mallet Harrington was using today at the Buick?

ps - I was really excited to watch the playoff....until America's Funniest Home Videos came on! What a bummer.

i am wondering what this was also

This is the only pic I could find guys.

It looked like a BG but, they never worm camed it like Sergio's.

I thought it looked like a Craze but no insert and something on the top. Could it be a wilson prototype?

I read in Golfweek that it was a Wilson Staff Light prototype or something like that. You can alter the weight on the putter to your choice and alter the alignment aids from lines, arrows, circles or squares apperently. I am not 100% sure if that is the putter he was using, but seems like it to me. I am looking for the article on golfweeks website but have had no luck.
