5 reasons why JP Duminy has flopped in Tests

#5. Inconsistent performances

The key reason for Duminy's below par Test career is his staggering inconsistency.

In 74 innings he has 14 fifty plus scores which translate into one fifty plus score every 5.28 innings. This conversion rate is too poor to sustain at the international level.

After his heroics in Melbourne, he scored his second hundred in 2012, then two more in 2014, one in 2016 and his last hundred in 2017. This wide gap between his big knocks has hampered his statistics and added to his downfall.

The Proteas batsman is the classic example of the 'boom and bust' player. When he was in form, he was the most elegant batsman on the ground, driving the ball in covers, cutting it to the square of the wicket and flicking it with quick wrists.

But when he was in bad form, his batting was the ugliest sight as he struggled against the length and failed miserably to time his shots.

This staggering inconsistency ensured that selectors and his supporters lost faith in him.
