Former Pakistan captain Urooj Mumtaz lauded youngster Razaullah, saying he wrote the "perfect chapter" to revive his reeling side after his sensational 81 off 63 balls against England on day three at Edgbaston.

Razaullah, who had only played eight previous first-class matches, smacked nine sixes, equalling Tim Southee's record for most maximums by a Test debutant, in a 121-run partnership with Mohammad Abbas (42) that propelled Pakistan to 449 and set England 130 to win.

The 21-year-old also took four wickets in England's innings, including skipper Joe Root for his first. His batting forced the match into a fourth day when Pakistan trailed by two runs at 318-8.

"His innings was simply sensational," Mumtaz said on Sky Sports. "A perfectly written first chapter. All that passion, the flair of Pakistan cricket! One 21-year-old who wasn't even on the list gets on the plane... Then Joe Root is his first Test wicket, he takes a four-fer on debut, and makes 81, with nine sixes. All of Edgbaston and all of Pakistan were on their feet!"

Mumtaz praised the spirit Razaullah embodied amid an off-field crisis that saw seven squad changes and a head coach axed. "He showed the beauty of Pakistan and their raw talent," she said.
