Veteran L Sarita Devi and rookie Manisha Maun gave India a flying start in the women's World Boxing Championships with dominating victories in their respective bouts here on Friday. While Manisha punched above her weight to outclass veteran American Christina Cruz in a unanimous verdict in 54 kg, the 2006 edition gold medallist Sarita (60kg) had to work harder to emerge 5-0 winner on points against Diana Sandra Brugger of Switzerland in their opening bouts at the KD Jadhav Stadium. Both Sarita and Manisha advanced to the pre-quarterfinals where they will face Kellie Harrington of Ireland and Dina Zholaman of Kazakhstan.
