NEW DELHI: All-rounder James Coles and experienced spinner Senuran Muthuswamy starred as Sunrisers Eastern Cape secured a commanding seven-wicket victory over Paarl Royals, booking their spot in a fourth consecutive SA20 final in Johannesburg.

The two-time champions will now take on Sourav Ganguly's Pretoria Capitals at Newlands, Cape Town, on Sunday.

After restricting the Royals to a modest 114 for seven on Friday night, Sunrisers chased down the target in just 11.4 overs, finishing at 117 for three. Coles led the charge with a sensational all-round display, claiming 1/15 from his four overs of off-spin before anchoring the chase with an unbeaten 45 off only 19 balls.

On a tricky surface that offered prodigious turn and bounce, few batters could cope. Coles wasted no time, punishing Dan Lawrence's first over for 21 runs and effectively putting the game beyond doubt.

Coles shared an unbroken 65-run partnership with Matthew Breetzke (19 not out) to seal the Royals' fate after Quinton de Kock has blitzed a rapid 25 off only 12 balls upfront.

The 21-year-old had earlier combined perfectly with Muthusamy (3/15) to set up the game for Sunrisers. The spin twins claimed four wickets for 30 runs from their allotted eight overs to restrict the Royals.

It was a struggle from the outset for the Royals after stand-in captain Lawrence won the toss and elected to bat.

Lhuan-dre Pretorius could not build on his form from the Eliminator and fell early when he chipped seamer Lutho Sipamla to Sunrisers captain Tristan Stubbs at mid-off.

From thereon, it was a battle for survival with Kyle Verreynne laying down anchor as the wickets continued to fall regularly at the other end.

Verreynne carried his bat for a workmanlike 52 not out off 46 balls, but had little support from the remaining Royals batters.
