Run out

An innings in cricket could be brought to a close if the batsman were run out. In the friendly between Cheldon Bonniface Invitation Eleven and the Doctor's Invitation Eleven, Bernice Summerfield was run out by Peter Hutchings. Running out was a relatively uncommon way for an innings to end. Indeed, Summerfield's was the only innings for either side to end in this fashion. (PROSE: Happy Endings)

Behind the scenes

Neither Happy Endings or any other Doctor Who story as of August 2017 ever describes precisely what it means to be "run out".
