Delhi Capitals (DC) on Wednesday beat Rajasthan Royals (RR) by 13 runs at the Dubai International Stadium and climbed back to the top of the IPL points table, even as the winning team's fast bowler Anrich Nortje bowled the fastest ball of the tournament history.

Defending a total of 161/7 wickets in 20 overs, DC looked off the pace for much of the second innings but the bowlers led by South African duo Nortje (2/33) and Kagiso Rabada (1/28) stifled the batting side for runs in the 'death' overs to take the game away from them.
