England will be taking on South Africa at Lord's this year, in a Royal London One Day International.
At the time of writing we're not having a very good run against them — losing the last two Twenty20 games. We lost the previous three 1-day internationals as well. But obviously they were just practice games — they don't count. We only count the games that take place at Lord's (unless we lose, of course, in which case they don't count either).
