Mark Wood is eager to inflict more torment on Marnus Labuschagne after dismissing the prolific Australia batter on a rain-affected first day of the fourth Ashes Test.

Australia closed on 126-3 after Pat Cummins won the toss and elected to bat first at the Sydney Cricket Ground on Wednesday.

Only 46.5 overs were bowled due to poor weather, with rain preventing England from making further inroads.

Stuart Broad got rid of David Warner (30) for the 13th time in the longest format and James Anderson had Marcus Harris (38) caught by Joe Root in the slips before Labuschagne edged Wood through to Jos Buttler.

England fast bowler Wood hopes he can claim the scalp of Labuschagne time and again after sending the top-ranked Test batter in the world on his way for 28.

The paceman said: "I'm delighted to get Marnus because he's a top player. I know we've had this bowl fuller thing but I think we have to hit the wicket hard and make them play as much as we can.

"Thankfully I made Marnus play, it wasn't an easy ball to leave, and he managed to edge it.

"I'd love to have a Broad v Warner thing with him. Anybody would love that when they think they've got a chance to get someone out.

"The ball before, Marnus hit me for four so I just tried to zone in a bit more. I knew the ball before was loose but I got this one spot on.

"You want to test yourself against the best players. I've been a bit frustrated in that I've felt in good rhythm and have been bowling well in this series without getting the wickets I would have liked but to get big players like that out makes you very happy."

Wood revealed he had been suffering from illness ahead of the fourth Test as England battle to avoid a 5-0 whitewash.

He said: "I had a bit of a rough night but I managed to keep just enough energy for the day.

"I had a bit of a stomach problem but I'm hoping that with a good night's rest and some food inside me I'll be right as rain tomorrow."

Although England were frustrated by rain, Wood was delighted they got the opportunity to remove Harris and Labuschagne before play was called off for the day.

"It could have been a good opportunity for us to get another couple of wickets but after a stop-start sort of day to get a couple towards the close was a big deal," he added.
