Mark Taylor issues reality check over Aussie centurions on day one of the second Test

Cricket great Mark Taylor believes Australia need to take their day one success of the Adelaide Test with a grain of salt after David Warner and Marnus Labuschagne bullied a listless Pakistan attack.

Friday's play couldn't have started any better for Pakistan as Australia were rocked early after Shaheen Afridi dismissed Joe Burns for just four runs.

But a lengthy rain delay followed and Australia came out firing with Warner and Labuschagne leading the way as Australia finished the day at 1-302.

Warner (166) and Labuschagne (126) punished the tourists with an unbroken partnership of 294 setting a new record for a second-wicket stand against Pakistan.

The giant innings also became highest second-wicket partnership against any nation at the Adelaide Oval.

Despite both batsmen putting on an incredible performance, Taylor labelled Pakistan's bowling attack as "ordinary" and said Australia needed to be realistic about their performance against an underpowered opponent.

"It was a very ordinary Pakistan attack today, there is no doubt about that," Taylor said.

"In a way that does detract from what David Warner and Marnus Labuschagne did.

"They really worked hard at the crease early on when it was a little bit tougher, and then when they worked the Pakistanis down they just didn't give them anything.

"At the end they just kept the pressure on and the last hour, hour and a half, Pakistan were absolutely shot.

"We're sort of in the same situation that we were in the Gabba Test match. There's a real lack of penetration with the ball. Execution-wise there's not a lot enough balls being bowled at the right area."

It was tough day for recalled medium-paced bowler Mohammad Abbas who struggled to have an impact.

The cricket great hit out at Abbas' performance, stating the 29-year-old's length was too short.

"I can see now why Mohammad Abbas didn't play the first test," Taylor said.

"It's not so much he's down on pace. He's down on length. He's too short. Too short for way too long today.

"I know he's not the most experienced bloke around, but he's played enough Test cricket to know you've got to bowl fuller than that."

Play will resume on Saturday half an hour earlier than scheduled to make up for rain delays on Friday night.
