Big-hitting New Zealand star Tim Seifert has scored his first BBL century, ensuring the Melbourne Renegades set Brisbane an imposing target in their season opener.

As Seifert and Ollie Peake ran amok, Shaheen Afridi was sensationally banished from the Heat attack by the umpires for bowling two full-toss no balls above waist height in the same over. He had 0-45 from 2.4 overs.

Adding to the drama, Seifert was injured while batting - apparently hurting a side muscle - and did not keep wickets on Monday night in cold conditions. Muhammad Rizwan took his place behind the stumps at Geelong’s GMHBA Stadium.

Seifert smashed 102 from 56 balls - making him only the second Renegades player to score a BBL ton - as Melbourne amassed 5-212.

“A little bit too many, I’d say ... it’s always tough to chase over 200, but we’ll go out and have a crack,” Heat opener Colin Munro told Fox Sports at the innings break.

It came a month after Seifert broke a finger while playing in New Zealand, forcing him out of the T20 series against the West Indies.

He and Peake, the home-town young gun, put on 121 from 57 deliveries for the fourth wicket.

Peake’s 59 from 29 balls made him the second-youngest BBL player after Sam Konstas to score a 50 and it showed again that the 19-year-old is one of Australian cricket’s brightest young talents.

Seifert was in blazing form from the start, hitting nine fours and six sixes in his ton.

When Jack Wildermuth bowled Jake Fraser-McGuirk for 10 in the 10th over, the Renegades were 3-82.

Seifert and Peake took the initiative, with the New Zealander continuing to maul the Heat bowlers and allowing his young teammate to settle into his innings.

The wheels well-and-truly fell off for Brisbane in the 18th over when Afridi’s two high full tosses meant he was taken off and acting captain Nathan McSweeney bowled the rest of the over.

It was a nine-ball over that conceded 22.

Opening bowler Xavier Bartlett was the standout, taking 1-24 from his four overs.
