As the statistically-minded would have noted, Adam Voges scored a century on Test debut in June and went on to complete 1000 runs by the end of 2015. He thus completed 1000 Test runs in the calendar year of his debut, becoming only the third to achieve this. This is not to be confused with scoring 1000+ Test runs in the first 365 days after his debut.
The only ones to have achieved this are:
MA Taylor (Aus) 1219@ 64.15 1989
AC Voges (Aus) 1028@ 85.66 2015
AN Cook (Eng) 1013@ 46.04 2006
The only Test players from India who scored over 500 runs in the calendar year of their debut:
SM Gavaskar 918@ 83.45 1971
S Ramesh 843@ 49.58 1999
VG Kambli 793@113.28 1993
Yashpal Sharma 591@ 39.40 1979
SC Ganguly 504@ 50.40 1996
It helps, of course, if you make your debut in the early part of the year (though Voges, Yashpal and Ganguly made their debuts in mid-year).
Update:
Spare a thought for M. Azharuddin, who had the misfortune to make his debut in a Test starting on 31 Dec 1984. He made 110 runs in Tests starting in 1984 and 495 in Tests starting in 1985.
