Australian speedster Mitchell Starc has challenged Craig McMillan to face him in the nets after the New Zealand batting coach questioned whether the left-arm pacer had actually bowled at 160kph.

In a blistering spell after lunch on the third day of the second Test match between Australia and New Zealand, Starc bowled a blazing yorker to Ross Taylor which was regulated by the Nine Network's speed gun at 160.4kph, the fastest recorded delivery in a Test match

But McMillan, who faced the fastest recorded delivery in an ODI against Pakistan at Lahore in 2002, queried the authenticity of the technology.

"I don't know, maybe someone in the truck was having a bit of fun but that delivery came out of nowhere and looked pretty similar to a lot of deliveries throughout the day that were closer to 150 than 160," Cricinfo quoted McMillan as saying.

"I'm not sure if maybe the wrong button was pushed, but you'd have to ask Rossco whether it felt 10kph quicker than any other delivery he faced."

McMillan was batting at No. 3 for New Zealand in 2002 when he faced Shoaib Akhtar’s delivery that was clocked by a sponsor's speed gun at 161kph.

"It felt more like 181 to be fair, Shoaib Akhtar at his quickest," joked McMillan.

"No, it just felt like a normal delivery. It was in different circumstances. I'd have to say I was a bit surprised when it came up on the TV because a couple of the spinners' deliveries were quite high as well. Maybe there was a technical problem down in the truck."

When informed of McMillan's comments, Starc replied back with a bold dare.

"Happy for him to face me in the nets tomorrow if he wants," he snapped with a resolute grin.

Despite the McMillan's doubts, Starc said it was the fastest spell he's bowled to date.

Running in from the Lillee Marsh End, his delieveries constantly recorded above 150kph in a spell that tested the spirit of Taylor and Brendon McCullum.

"I was trying to bowl quick. It was nice to have a nice run-up in and not have to jump up to the square, have a nice breeze" Starc said.

"It was all sort of working nicely for the left-armers at this end. Nice to have some rhythm, have the ball coming out nicely. Unfortunately I couldn't get a couple of wickets to go with it."
