His innings powered England U-19 to a four-wicket win over Bangladesh U-19, leveling the series 1-1.
Batting first after winning the toss, Bangladesh looked solid with Jawad Abrar and Rifat Beg giving a brisk start.
Jawad fell for 10, but Rifat’s fluent 51 off 52 balls and captain Azizul Tamim’s 41 anchored the innings.
Rizan Hossain continued his fine form with 57 after scoring a century in the previous game, while Al Fahad added a useful unbeaten 25.
However, regular breakthroughs by the English bowlers restricted Bangladesh to 272 in 47 overs.
England, led by Isaac’s fireworks, comfortably chased down the target to square the three-match series.
