Can you tell me the Player that has the Country of united states, and the Score of 77-72-72=221?
CREATE TABLE "third_round" (
  "place" text,
  "player" text,
  "country" text,
  "score" text,
  "to_par" real
);
SELECT "player" FROM "third_round" WHERE "country"='united states' AND "score"='77-72-72=221';
