Karim Khan of Children's Academy and Arjun Chatterjee of Jamnabai Narsee scored convincing victories to set up a clash in the semi-finals of the Mumbai Schools Sports Association-organised boys' U-16 inter-school lawn tennis championship at Azad Maidan yesterday.

In a quarter-final match, Karim hardly encountered much resistance from Ayan Tezabwala of Campion School (Cooperage) and charged to a 6-1 victory. Karim with some powerful returns broke Ayan's serve in the first, fifth and seventh games to wrap up a quick win and advance to the penultimate round. Later, Arjun too produced a solid performance against Yash Kothari of PG Garodia School and romped to a 6-1 win.
