Pardon the glare: One of NYC’s premiere sports shops, Paragon, is all decked out for the Open — Union Square style. In their maze of a store, the tennis sway is right when you walk in the front door off of Broadway. What they still have? There’s a couple of those oh-so-beautiful HEAD racquet bags from Murray’s Wimbledon (sans the fan notes) ready for pick up. And from what we’ve heard, they’ve been a hot item and will be virtually impossible to find once they sell out.
