means To close, strike, or defeat with sudden, forceful impact — a hard hit delivered all at once.

from Slam shows up in the 1600s-1700s, likely echoing the sound itself — a bit of onomatopoeia for a door or fist hitting hard. It picked up its card-game sense (as in 'grand slam') in the 1600s through games like whist, and from there leapt into baseball and sports generally, where winning big became winning 'in a slam.' The exact root is murky, possibly linked to Scandinavian words for banging or striking, but mostly the word just sounds like what it means.
