Sai Sudharsan stars as Gujarat Titans power past Delhi Capitals in IPL

Sai Sudharsan's half-century and a whirlwind cameo from David Miller powered holders Gujarat Titans to a six-wicket win over Delhi Capitals in the Indian Premier League on Tuesday.

Gujarat pace spearhead Mohammed Shami and leg-spinner Rashid Khan took three wickets each as they restricted the opposition to 162-8 before handing Delhi a second straight loss.

Gujarat did not have the best of starts as Nortje removed both openers, including bowling Shubman Gill for 14, and were in further trouble when left-arm quick Khaleel Ahmed got skipper Hardik Pandya caught behind for five.

But Vijay Shankar replaced Ireland fast bowler Josh Little under the new "impact player" rule introduced this season and joined Sudharsan in the middle to revive the chase.
