Obviously an 11 man cricket team, as should have been clear from the second quotation.

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.
