Joe Root is currently going through his longest streak without a century in Tests. He has picked up nine half-centuries in 16 innings since his last century in August last year, against West Indies.

The England captain’s low conversion rate saw him play the Ashes series and the New Zealand Test-series without scoring a single century.

Root believes that he has been very consistent. He has been trying to overcome the flaws that haven’t allowed him to convert the fifties into three-figures, while maintaining the mental approach that has helped him with his consistency.

“It can change very quickly,” he told Sky Sports. “I've got to keep trusting in my own game and making sure that I'm constantly trying to evolve and get better, but also have the same mental approach that I have because I have been very consistent with the bat.

“I'm sure it's just a matter of time and there will be one or two innings where it just clicks into place and I'll go on a little run of big scores. I've just got to keep searching for it, trusting it and believing it and I know eventually it will happen.

“When you're losing it is very hard because you look at that and you think sometimes the difference is going on and making big hundreds.

“One thing I will say is that if I keep getting up and beyond fifty and I start going on a bit more frequently then we'll be in a strong place as a side and I'll be scoring a lot more runs.”

Only three of Root's record twelve consecutive Test fifties were converted into a three-digit score. He scored seven fifties during the Ashes and none of those were converted into a century.
