The 1947–48 series against the West Indies was another disappointment for England, with the side losing 2–0 following injuries to several key players. England suffered further humiliation against Bradman's invincible side in the 1948 Ashes series. Hutton was controversially dropped for the third Test, and England were bowled out for just 52 at The Oval. The series proved to be Bradman's final Ashes series.
The Laws state that, throughout an innings, "the ball shall be bowled from each end alternately in overs of 6 balls". The name "over" came about because the umpire calls "Over!" when six balls have been bowled. At this point, another bowler is deployed at the other end, and the fielding side changes ends while the batsmen do not. A bowler cannot bowl two successive overs, although a bowler can (and usually does) bowl alternate overs, from the same end, for several overs which are termed a "spell". The batsmen do not change ends at the end of the over, and so the one who was non-striker is now the striker and vice-versa. The umpires also change positions so that the one who was at "square leg" now stands behind the wicket at the non-striker's end and vice-versa.
