2780 Deliveries faced by Alastair Cook in Tests in 2015, which is 1008 more than Joe Root's 1772, the next-best this year. Those two are also the only batsmen with 1000-plus Test runs so far this year: Cook has 1235 runs at an average of 61.75, while Root has an aggregate of 1195 at 70.29. Cook's aggregate deliveries faced this year currently puts him in tenth place in the all-time list (among years where complete ball-by-ball data is available). The most balls played by any batsman in Tests in a calendar year is 3237, by Rahul Dravid in 2002. Cook is currently 457 behind that mark.
