Andy Murray earned his biggest tournament victory ever, beating Novak Djokovic in two tiebreaks with a controlled performance in the final of the Cincinnati Masters this afternoon. This was Murray's second win over the Serb in as many weeks.
Murray served for the match at 5-4 in the second and squandered four match points. It looked like the Djoker might be able to carry the day if he could get to a third set, but a brilliant exchange at 4-all in the tiebreak, punctuated by a Murray crosscourt backhand winner, provided the critical edge.
Based on current form, these two 21-year-olds are the most capable challengers to the Nadal/Federer stranglehold on the game's top spots.
