Adam Zampa claimed an unwanted record while Travis Head gave Australia a World Cup injury concern as they were thrashed by 164 runs in the fourth one-day international against South Africa.

Zampa bowled 10 wicketless overs for 113 – equalling the worst figures in an ODI, held by fellow Australian Mick Lewis – as Heinrich Klaasen propelled South Africa to their third-highest total.

Klaasen smashed 174 of just 83 balls as the hosts posted 416-5 at Centurion to level the five-match series 2-2, having lost the opening two.

Of greater concern for Australia will be the injury to opener Head, who retired hurt three balls after being hit on the left hand by Gerald Coetzee.

Australia coach Andrew McDonald confirmed x-rays had shown a fracture with the World Cup just three weeks away.

McDonald said: “He’s going to go in for some more scans tomorrow to work out the detail of (the injury) and then we’ll work out the management from there. How long that (recovery) time frame is, we’re yet to determine.”

Australia already have injury concerns over Pat Cummins, Steve Smith, Mitchell Starc and Glenn Maxwell, while Cameron Green was concussed in the first game of the series.

Klaasen described his assault, which included 13 fours and 13 sixes, as “one of my better ones”.

He was caught on the boundary off the final ball of the innings, ending a stand of 222 with David Miller who smashed an unbeaten 82 from 45. Rassie van der Dussen also hit 65.

Michael Neser was the only Australian bowler to go for under seven runs an over, Zampa conceding nine of the 20 sixes hit by the hosts

Australia’s reply never really got going, wicketkeeper Alex Carey the only batter to face more than 25 balls but he was last man out for 99 as Australia were dismissed for 252.

The Texas Super Kings advanced to the playoffs of the inaugural season of Major League Cricket after a three-wicket win over the San Francisco Unicorns in their fifth and final league phase game at the Church Street Park in Morrisville, North Carolina on Monday.

The Unicorns won the toss in the winner-take-all encounter and decided to bat first.

Matthew Wade led the way with 49 while Chaitanya Bishnoi made 35 as the Unicorns posted 171-8 off their 20 overs.

Pacer Gerald Coetzee took 4-31 off his four overs for the Super Kings.

Texas then reached 172-7 with five balls to spare.

Milind Kumar set the foundation for the successful chase with a 42-ball 52 before Daniel Sams hit a whirlwind 18-ball 42 including two fours and four sixes to help seal qualification to the playoffs.

Haris Rauf and Shadab Khan each took a pair of wickets for the Unicorns.

The Seattle Orcas, Texas Super Kings and Washington Freedom have all confirmed their spots in the playoffs.

The final spot will be determined on Tuesday when the Orcas face MI New York. MI New York and San Francisco both have four points with New York ahead on net run rate. MI New York would seal their spot in the playoffs with a win or by avoiding a heavy defeat. If they lose by at least 130 runs, they would finish fifth and the Unicorns would advance.
