It does appear to be a cricket term. I have also heard the term "Elevens" used in British Victorian novels which I think means some sort of mid-morning meal. It must be like an American brunch. I don't know if that term is in current usage or not.We would need a Brit to answer that question. I doubt in this case this is what is being referred to but it's an interesting little history note none the less.

A term derived from English public schools (N.B. in England public school is what an American would call a prep school), an eleven is a cricket team, a fifteen is a rugby team (due to the respective numbers on the teams); sometimes an eleven means a football [soccer] team. Used especially as the 1st XI (the best cricket team in a school), or 1st XV (the best rugby team).
