I saw that Jacques Kallis passed 2000 runs in Tests against West Indies the other day. Has anyone else scored more, against West Indies or anybody? asked Joubert Franck from Cape Town

Jacques Kallis was actually the sixth man to reach the milestone of 2000 runs in Tests against West Indies. He now has 2073 runs against them, just ahead of Allan Border (2052), but still behind Steve Waugh (2192), Graham Gooch (2197), Geoff Boycott (2205) and the clear leader Sunil Gavaskar, whose 2749 runs included a record 13 centuries against West Indies. Kallis, though, averages 74.03 against them, the highest of anyone with more than 2000 runs. The record against a single Test opponent is held by the one and only Don Bradman, with 5028 for Australia against England.

Have any teenagers ever played Test cricket for England? asked Tim Milgate

The youngest man ever to play for England was Yorkshire's Brian Close, who was 18 years and 149 days old when he made his Test debut against New Zealand at Old Trafford in 1949. Two other teenagers have represented England in Tests: Denis Compton and Ben Hollioake were both 19 when they made their debuts in 1937 and 1997 respectively. Compton made a century against Australia at Trent Bridge in 1938, just 19 days past his 20th birthday, and remains England's youngest Test century-maker.
