36th over
The New Zealanders are still holding them back, but that crucial wicket is evading them. One run to bring up the 50 stand is all O' Brien yields from that over.
37th over
Spark goes over the top! He's had enough of Oram's military medium and takes him for a one-bounce four past long on. Riley late cuts yet again to the boundary, nine more to the total.
38th over
Spark continues to charge, and lofts O' Brien over cover for four more. It's in the bag now, surely?
39th over
Yep, they are making it look easy now. Riley clips a four through midwicket, there's four more singles, and a Spark cover drive to the boundary gets him past fifty from 82 balls. A chanceless, crucial knock. Oram's figures are ruined from the last two overs, he's taken 0-44 in his 10.
40th over
Straight drive from Riley brings him four more, and that's seven from O' Brien's final over of his 1-38.
