Looks like Steyn really owned Bisla ...just wasn't able to get him out. I count one ball where he was probably in control

1.2 Steyn to Bisla, no run, The crowd are screaming RCB as Steyn rushes in to bowl. Lovely delivery, shaping away late, and moves past the defensive prod .. and the keeper collects
1.3 Steyn to Bisla, no run, Almost ... cleaned up .. it cut away late from the leg and middle line, the batsman is almost squared-up and manages to edge it away to backward point
1.4 Steyn to Bisla, no run, Another one going away from the off stump and Bisla is all at sea. They have a nice word in hindi for this - Aukat!
1.5 Steyn to Bisla, 1 wide, pushes this down the leg side ... Boucher dives to gather it
1.5 Steyn to Bisla, FOUR, fast pacy lifting deliver into the ribcage .. Bisla is in a awkward position, takes the bottom hand of the handle and fends it off in an ungainly fashion .. the ball is i n the air and just wide of the diving Boucher down on the leg side
1.6 Steyn to Bisla, 1 run, pushes this short of length delivery to the point region
4.2 Steyn to Bisla, 1 leg bye, Almost run out jabbed out to the off side ... and Steyn rushes across, picks the ball and flicks the throw but misses the stumps ... Had he hit the stumps, Bisla, who was diving to get inside the crease, would have been a goner
4.4 Steyn to Bisla, FOUR, Ouch! A nasty bouncer on the m iddle stump line, Bisla tries to duck and get out of the way at the last minute. Too late. The ball kicks up and flies off his helmet ( I think) over Boucher .. Given as runs .. may be there was some gloves involved .. not sure
4.5 Steyn to Bisla, 1 run, he is really going after Bisla here. Another short one, into the rib cage this time, stabbed away awkwardly to the on side
