Jerzy Janowicz and Nike
I was surprised to see Janowicz show up at the Paris final and not have had Nike intervene and kit him out in a set of current gear. He was still wearing a mixed set of older styles as in his other matches (it looks like his deal is a local deal from back in Poland given he's also got other sponsors patches on his shirt).
I'd have thought, as has happened in the past, when a player has a random dream run like he did the sponsor would make sure they're kitted out in a current range for a big match, especially given how much attention he received.
