Pat Cummins' 37 balls is the longest an Australian has taken to get off the mark in Test cricket since 1991.

I know it is his debut, I know he has dismissed Steve Smith and I know he has taken a wicket with a short ball but I worry about Craig Overton's pace at this level. He bangs one in to Pat Cummins but it is only 79.7 mph. Cummins' looseners are 10mph quicker than that. The Aussie number nine can't add to his one scoring shot so far but he looks comfortable.

Moeen's got to toss a few up. You need to get up on your tippy toes, on your pivot foot, and get high. Think high and bounce and loop.

Rubbish from Moeen Ali. England have plenty of problems in this series but one of the biggest is the form of Moeen Ali. He bowls another half-tracker and Shaun Marsh whips it off the stumps to the mid-wicket fence. Ricky Ponting says on the TV commentary that Joe Root has looked a more effective spinner than Moeen. Ouch.

Craig Overton is back into the attack replacing Stuart Broad. His two wickets in this innings have seen Root turn to him before Chris Woakes again today.

Huge cheers! Pat Cummins has done it! He has scored a run off his 37th delivery and it's a four. A guided cut wide of gully. You'd think he'd reached a half-century with the volume of those cheers.

Pat Cummins has got beautiful eyes. Blue chips for eyes! He's not looking to score. He could possibly move up a touch in the batting order.

Still Cummins can't get away! He chops a cut off Anderson and Mark Stoneman dives well at backward point to keep the pressure on.

Now Anderson finds the edge but the ball drops way short of Jonny Bairstow! That was a regulation edge. Are we in Adelaide or Dhaka? Jimmy just laughs but I don't think he's too happy inside. He's had no luck.

34 balls and counting for Cummins now.

I feel 50% of England's deliveries have been too short. They've bowled fuller today but they let things slip yesterday.

Rob in Manchester is not impressed. Is that a fair reflection?

Both Broad and Anderson are still keeping Cummins pinned on nought without creating any danger. The crowd are getting a little frustrated. They groan as Cummins hits the 28th ball he has faced straight at the cover point fielder.

The run-rate is below two for this session. Australia are just keeping England out there.

Shaun Marsh ran through for a leg bye while England were appealing for that lbw so Anderson has Pat Cummins to bowl to for the rest of the over. Still Cummins is happy to just dig in. He's still yet to score from 24 deliveries. What did England used to say about dots and pressure?

Another lbw goes begging.

You might as well burn one of your reviews there. To get rid of Marsh now and get the two tailenders in would be just what they want.

Still no luck for England with the review system. The ball would have knocked off stump out of the ground but it pitched outside leg stump.

Marsh survives.

Another big shout for lbw. Has Anderson got Marsh? The umpire says no but Joe Root calls for a review.

England are doing a good job of keeping Pat Cummins on zero but Cummins doesn't look to be fretting like Mitchell Starc did before him. He's just happy to play a solid forward defence when Broad bowls on the stumps.

Cancel that. The final ball is short from Broad and Cummins tries the ramp over the slips. He fails to connect but you had me fooled, Pat. Another maiden to Broad.

Jimmy Anderson's hands have spent as much time on his head today as they have grasping the pink Kookaburra. He bowls a nice, tight over, beating the inside edge with the first ball before all the good work ruined on the final delivery. A little over-pitched and Marsh comes forward and plays a square drive to the fence.

This total already has an ominous feel about it.

Sean: Spot on Glenn M. Declare today and have a session at England. Open with Lyon too for an over or two as well. England fan here but we don’t mix it up enough.

The floodlights are on but this match is now being played under clear blue skies in bright Australian sunshine. There are a few topless fans in the crowd.

After the barrage of short stuff in the last over, Broad is tempting Cummins outside off stump. He isn't interested though and when Broad pitches in line with the stumps Cummins plays a solid forward defence. He looks relatively comfortable.
