A brilliant century by 19-year-old debutant Abhinav Mukund,who scored 108 runs,and an unbeaten 93 by skipper S Badrinath enabled Tamil Nadu score of 289 for 5 in the first innings on the first day of the Ranji Trophy match against Karnataka, at the M A Chidambaram stadium in Chennai on Friday.

Tamil Nadu, who went into the match under pressure -- with just one point from two matches, won the toss and put up a confident show with the bat as Mukund and Badri combined well.

With Badrinath, who is batting on 93 off 212 balls hitting seven fours and two sixes, Abhinav added 139 runs for the third wicket in 161 minutes.
