After finishing as runners-up in the ICC Champions Trophy, England faced Australia in back-to-back Ashes series. A 3–0 home win secured England the urn for the fourth time in five series. However, in the return series, they found themselves utterly demolished in a 5–0 defeat, their second Ashes whitewash in under a decade. Their misery was compounded by batsman Jonathan Trott leaving the tour early due to a stress-related illness and the mid-series retirement of spinner Graeme Swann. Following the tour, head coach Flower resigned his post while Pietersen was dropped indefinitely from the England team. Flower was replaced by his predecessor, Moores, but he was sacked for a second time after a string of disappointing results including failing to advance from the group stage at the 2015 World Cup. He was replaced by Australian Trevor Bayliss who oversaw an upturn of form in the ODI side, including series victories against New Zealand and Pakistan. In the Test arena, England reclaimed the Ashes 3–2 in the summer of 2015.
This loss saw the resignation of Strauss as captain (and his retirement from cricket). Cook, who was already in charge of the ODI side, replaced Strauss and led England to a 2–1 victory in India – their first in the country since 1984–85. In doing so, he became the first captain to score centuries in his first five Tests as captain and became England's leading century-maker with 23 centuries to his name.
