Last year, the White Sox debuted the K-Zone for Sale – See post from April of last year — https://mostlysox.com/2014/04/01/k-zone/
or the follow-up from August when Hawk & Stone were in the Zone — https://mostlysox.com/2014/08/07/in-the-zone-with-hawk-stone/
Instead of the K-Zone T-shirt, fans who sit in the Shark Cage receive a free cap.
Of course, you also get a K-Card, but this one is shaped like a Shark fin.
I think the Shark Cage Logo is quite good.
Here’s the view of Jeff pitching — from my seat in the Shark Cage. Jeff didn’t have his good stuff and we only got to use the K-Card 3 times. He yielded 6 hits and 2 walks, but managed 6 shutout innings and the Sox won 6-0 for Jeff’s first win as a member of the White Sox.
