The truth is, everyone is nervous when they are exposed to the highest level of cricket. The pressure is always on. We should take into consideration his inexperience and youth. Newbies look to seal a spot within the team and then getting a ton in the second debut match is a treat to enjoy
he pretty much played shots all over the park. He has good, clean hitting ability. Now that he has a hundred hopefully his nervousness is gone and He can carry the momentum on-wards....
If his spot in the team was sealed and he was a bit more experienced, i reckon He would have gotten his century earlier but hey, from someone on his second match, that's pretty good by any international standards you set
