Who's idea was it to put Bozoljac in this match?
The only other alternative was Troicki!
It would have been a risk to play Tipsarevic, considering his marathon with Stepanek yesterday. Sure, Stepanek did actually play the doubles today, but the Czech pairing (Berdych and Stepanek) would have been favoured against him and Zimonjic.
Tipsarevic has now had some rest ahead of his singles against Berdych, so that should help him a little. If he is somehow able to level the tie again for Serbia, a rested Troicki might fancy his chances against a weary Stepanek. Fitness is about the only edge Troicki could hope for at the moment, really.
Smart decision by Serbia captain today, and a bold move by the Czechs to risk Stepanek's fitness. Paid off very nicely.
