South Africa has taken an unconquerable lead of 2-0 in the three-match Test series against India. The minor mistakes of visitors, which may look small but has cost them big time. There were few drop catches and soft dismissals from India. They also lost important wickets at crucial stages to run-outs.

Cheteshwar Pujara, one of India's most reliable batsmen in Test was dismissed with run-out in both innings of 2nd Test at Centurion. Neither fans nor the head coach is happy about it. 

Ravi Shastri on Monday said the team will have to rectify the "schoolboy errors" that led to three run-outs in the lost second Test against South Africa, insisting that conditions are hard enough and these silly mistakes will only make things tough for them.

"It hurts a lot. As it is the conditions are very tough, and on top of that, if someone gets run out then you feel bad and there is no doubt of that. You hope that those mistakes don't happen again because at times they are schoolboy errors," Shastri said.

Hardik Pandya's run-out was a result of his casualness and left India struggling in the middle. Shastri isn't happy with the way wickets were gifted by Indian batsmen. Not only with the run-outs, but the loose shots. 

"They have to be rectified. In tough conditions like these, where there is not much between the two teams, you cannot afford to give away wickets like that. Boys have been told that," Shastri said.
