Sharp (Bettor)
A highly skilled or professional sports bettor who wins consistently and often moves lines with their bets. Sharps (or “wiseguys”) exploit discrepancies between their own odds and the book’s odds, and sportsbooks track their action closely.
A **sharp** might spot that Crawford should be +100 (50% chance) but is listed at +150 (40% implied). They’ll bet big on Crawford; if multiple sharps do so, the odds will shift. Being labeled a sharp bettor by sportsbooks can lead to betting limits or quick line adjustments when you bet.
