Karnataka now have a lead of 24 runs and have ensured three points from the game.
After the match started an hour and half late due to bad light, Karnataka opener Karun Nair batted well for his patient unbeaten knock of 92 while Binny attacked the spinners hitting some effortless sixes off the spinners to score 88 off 94 balls.
It was Binny who brought some life into the match as he hit Varun Sood for three sixes - two over long on and another over long off.
Another six came off Manoj Chauhan who rarely got his length right. In all, he batted for 94 balls hitting four fours.
While Nair was content in taking singles and hitting the odd boundaries in between, Binny was in his free flowing self. During tea-break, he got the news of his selection and post break completed his 50. As if to celebrate the selection, he hit Manan Sharma over extra cover for a fifth six as they completed their century partnership in the 62nd over.
