"Our top order could not do well, some more runs on board could do better. A total of 170 or some 30 to 40 runs on board could have been a good total and not an easy one to chase," Upton told reporters.
Earlier in the match, RCB easily chased a total of 130 runs by losing just one wicket of Chris Gayle.
When asked about the poor selection of shots by RR's batsman especially the young players, Upton said he was not disappointed with them as they had played as per the specific directions given to them.
Upton also said the momentum shifted to RCB when Karun Nair was run out on 16 runs and his team lost three wickets in 72 runs on board.

He said the RR has batting depth upto nine players, but as their middle order did not get exposure in earlier matches, they could not do well in this match.
While, RCB pacer Mitchell Starc, also said that the run out of Karun Nair by local boy Harshal Patel in crucial time has shifted to momentum to his team and it helped them to restrict RR in 130 run.
Starc, who took three wickets in game, said his team did not do good wither with bat or bowl, but they have improved their performance in all sides of the game.
Kohli has also played a good knock in the game and RCB has hopes that he will continue with such performance in the next games, he said.
