Bartunkova beats Ruzic in straight sets in Monterrey
Nikola Bartunkova came through her Monterrey opener with a controlled 6-4 6-3 win over Antonia Ruzic, taking each set with a single decisive burst. The Czech landed only 51.7% of her first serves but made them count, winning 70.0% of those points and adding three aces to Ruzic's none. The difference lay in the second delivery: Bartunkova won 57.1% behind hers, while the Croat, despite a tidier 67.2% first-serve rate, took just 42.1% of her second-serve points and repeatedly handed back initiative. Both players struck three double faults. It was a clean, efficient start to Bartunkova's week.
