Hewitt shouldn't play singles, he simply can't play at that level two days straight. As daft as it sounds, I'd stick with Kokk and Kyrgios for the reverse singles. It's time for Kyrgios to stop whinging and stand up for his country - whether or not he will do that remains to be seen. Kokk is average on grass but Nedoyesov is a better match-up, unless they bring in Golubev. Groth doesn't have the mentality to win a live singles rubber at this stage, despite his excellent performance today.
