Runner (Beard)
A person who places bets for someone else. Sharp bettors or syndicates sometimes use “runners” (also called beards) to avoid detection or betting limits. The runner is acting as a proxy, allowing the real bettor to stay anonymous to the sportsbook.
A known sharp might send a **runner** to put \$10,000 on Crawford at various casinos so that books don’t know the bet is coming from him. The **beard** makes the bets in his own name/cash, masking the involvement of the sharp bettor.
