Right so, Tim Ludeman and Mahela Jayawardene walk out, Andre Russell has the new ball.
WICKET! That's an early blow. Shane Watson strikes in his first over! He was hit for a mighty six by Mahela over mid-wicket just of couple of balls ago. Brilliant comeback from the bowler though. Tad bit outside the off, takes a slight edge and the keeper makes no mistake. The home team have lost their first man in the second over. Travis Head, the man in form, walks out and is off the mark with a single.
What a brilliant catch that from Andre Russell! McKay comes into the attack and removes the second Adelaide opener. Ludeman tried to flick it, only to give away a top-edge. Russell had his eyes on the ball all the time, runs backward and takes a brilliant catch to put an end to Ludeman's stay. Second one down, and Adelaide skipper Brad Hodge is the new man in.
