Test Match #2241: India vs England
a) Karun Nair becomes the second Indian batsman to score a triple hundred in Test match cricket.
b) Karun Nair becomes the fastest to score a triple hundred in just his 3rd Test innings.
c) But most importantly Karun Nair improves his highest Test score from 13 to 303 not out, a whopping improvement of 290 runs !!! beating Tip Foster who scored 287 on debut (!!!).
Now, thats what you call improvement.
By the looks of it, he should have a decent career ahead.
