Klaasen has been part of a powerful Hyderabad batting lineup alongside Abhishek Sharma, Travis Head and Ishan Kishan, with the hosts passing 200 in three of their last four matches.
Sunrisers sit third with six wins from 10 games, but need a response after their five-match winning run ended against Kolkata Knight Riders.

Jansen gives Punjab an option in an all-round group that also includes Marcus Stoinis. Punjab remain top of the table, but back-to-back defeats have cut into the early momentum built by six wins from their first seven matches.
The reverse fixture went Punjab’s way earlier this season, although Hyderabad lead the overall head-to-head 17-8.
With both teams priced evenly, Klaasen’s middle-order role and Jansen’s all-round value could shape a high-scoring contest in Hyderabad.
