Australia seize control as Smith's masterclass extends lead to 254

Steve Smith's magnificent 71 guided Australia to 221 for seven at stumps on day three of the second test against West Indies in Grenada on Saturday, helping the tourists to build a commanding 254-run lead despite late wickets and persistent rain interruptions.

Australia, who began the day two wickets down after losing Sam Konstas and Usman Khawaja on Friday, made it to lunch at 69 for three and appeared vulnerable on a pitch offering variable bounce and seam movement.

Nathan Lyon's nightwatchman role lasted 33 balls and yielded eight runs before he fell to Alzarri Joseph, with John Campbell taking the catch at third slip.

At that point, Australia were crying out for some heroics, and up stepped Smith and Cameron Green, who combined for a crucial 93-run partnership that turned the tide inexorably in the visitors' favour.

Green contributed a vital 52, his highest score batting at number three, before falling immediately after reaching his half-century when he chopped a Shamar Joseph delivery on to his stumps.

Smith, back in the side after missing the first test with a finger injury, found his rhythm after a cautious start, smashing a six off Roston Chase and hitting seven boundaries in a patient knock that spanned 119 balls.

The veteran looked in complete control as he guided Australia through the middle sessions but his masterful innings ended when he was given out lbw to Justin Greaves after an unsuccessful review.

"We're in a nice spot," Smith said. "I don't think the wicket is going to get any better, it will probably do a few more tricks.

"The new ball is going to be pretty crucial for us. Hopefully we can get up to somewhere around 300 and then we'll see how it goes."

Travis Head provided explosive support with 39 from 60
