Medium pacer Stoinis comes back into the attack.

Williamson runs the first ball down to thirdman for one before Bairstow flicks a full toss over midwicket but can't get it in the gap for another run.

Bairstow clips the next on the leg side as Dhawan is unable to get under the ball at deep square leg as it goes over him for a four.

The next ball is full as Williamson lofts it down the ground over the fielder at mid-on for another four, followed by singles off the last two balls, to get 12 from the over.

Rabada, who has two overs in hand, comes back for his final spell.

Bairstow gets two runs off the first ball as he digs out the yorker through square leg for two runs to complete his half-century from 44 balls and also raise the 50-run stand for the third wicket from 35 balls.

The slower ball from Rabada as Bairstow has a big swing but misses

SunRisers nearly lose a wicket as Williamson is sent back as he turns back for the third but he recovers in time and makes his crease before the stumps are broken by the bowler.

Another well disguised slower ball from Rabada as Bairstow is beaten all ends up.

Rabada finally gets his man as Bairstow is dismissed trying to force the pace. Bairstow, who made a sedate 53 from 48 balls, tries to loft it down the ground but skies it high and is caught at long-off by Nortje as SunRisers lose their third wicket.

Debutant Abdul Samad is the new batsman but Williamson retains strike with one from the last ball.

SunRisers are 145-3 in 18 overs and will hope for a strong finish to post a total of around the 175-run mark.
