Western Australia 207 (Richardson 53, Worrall 7-64) & 5 for 313 (S Marsh 163*, Bosisto 58, Worrall 3-84) beat South Australia 251 (Head 87, Winter 53, Richardson 5-47) & 268 (Nielsen 82, Cooper 49, Kelly 5-61) by five wickets

Any doubts about Shaun Marsh's place in Australia's Test side have been erased after his masterful 163 not-out helped Western Australia successfully chase down 313 against South Australia at Adelaide Oval.

Marsh began the day on 72 not-out with the Warriors still needing 167 with six wickets in hand. Marsh cruised to his second century in eight days early in the morning session.

He was savage on any width offered from the Redbacks quicks while he destroyed the legspin of Lloyd Pope, who simply could not find his length.

Marsh got ample support from William Bosisto, who stonewalled the Redbacks in the fifth-wicket partnership of 164. Bosisto made 58 from 189 balls with three fours and a six, blunting everything the home side threw at him while Marsh flourished at the other end.

Marsh gave the Redbacks one opening when Daniel Worrall took the second new ball. He edged an outswinger that fell inches short of Callum Ferguson at first slip.

Bosisto was dismissed by Joe Mennie with 36 runs still needed but Josh Ingles joined Marsh who went past 150. He struck 22 fours and two sixes during his 264-ball innings.

The Warriors got home with five wickets to spare well before tea on the final day.
