Should a batter hit a grand slam home run to end a game (a so-called walk off grand slam), the batter would be credited with 4 RBIs, no matter what the score was at the time. When a home run ends a game, all runs count, unlike another base hit that scores the winning run or runs. In that case only enough runs that put the team ahead counts..not so for home runs.
It's called a "grand slam."
Caroline Woznjacki didn't win Grand slam titles
A true Grand Slam in tennis is when a player wins all four Grand Slam tournaments in the same year. Otherwise it is just a career Grand Slam, and not a true Grand Slam.
