Rohit Sharma's maiden ODI century went in vain as a slipshod India slumped to an embarrassing six-wicket defeat against Zimbabwe in the first match of the cricket tri-series here on Friday.

Rohit's well-paced 114 and Ravindra Jadeja's unbeaten run-a-ball 61 had guided India to a decent 285 for five but the lack of sting and firepower in their bowling attack allowed Zimbabwe to romp home with 10 balls to spare.
