Former Australia skipper and a mentor of the side during the ongoing Ashes, Steve Waugh, heaped praise on Steve Smith, comparing his run of form to that of Sir Don Bradman.

Smith, who returned to Test cricket, following his suspension in the ball-tampering saga has scored as many as 671 runs across five innings in the Ashes 2019 with a help of three hundreds, including a double hundred, in addition to two innings of 82 and 92.

“I think only he could explain that. It’s a phenomenal performance. It’s monumental when you look back on it.” Waugh was quoted as saying by the BBC on Saturday.

“To be out of the game for so long, to have so much pressure and to do so well, it’s almost incomprehensible what he’s done,” continued Waugh.

“It’ll go down in the history of the game as one of the great performances by an individual in a series,” he added.

While Smith did not play the third Test after being hit by a Jofra Archer bouncer in the the first innings of the second Test, he showed no signs of nerves as he returned to the playing XI for the fourth Test and scored 293 runs in the match – 211 in the first innings and 81 in the second.

Waugh said that Smith is making run-scoring look too easy and batting on a different level. “I obviously didn’t see Don Bradman play, but I guess it’s in a similar sort of vein,” Waugh said.

“He just keeps scoring runs and it almost looks too easy. He’s playing on a different level to everyone else.

“I guess you’ve just got to cash in while it lasts because we know cricket can turn around pretty quickly. But right now he’s making the most of some great form,” concluded Waugh.
