Does somebody knows what is going on with Paire's racket?

Yesterday during the match against Nishikori he seemed to complain about the time that the stringing job took. I heard the French commentators say that he had merely three rackets in his bag, and at some point in the match, the strings one of them were broken, et the other one was being strung... leaving him only with one!

I believe he uses an AeroPro Drive, or Pure Aero, not sure how it's called these days but you've understood the racket I refer too. Is it another Mannarino case?

Thanks!
