As a baseball aficionado with a deep knowledge of the game's history, I am well-versed in the remarkable feats achieved by players throughout the years. The question you've asked pertains to one of the rarest and most exciting plays in baseball: the walk-off inside-the-park grand slam. This is a home run that not only ends the game but also does so with the runner circling all the bases to score the winning run, all in one swing.

The player you are referring to is indeed Roberto Clemente, a legendary figure in Major League Baseball. His achievement took place on July 25, 1956, during a game between the Pittsburgh Pirates and the Chicago Cubs at Forbes Field. The game was tightly contested, with the score tied at 8-8 in the bottom of the 12th inning. Clemente stepped up to the plate with the bases loaded and two outs. Facing the Chicago Cubs' pitcher, he hit a drive that cleared the bases, allowing all four runners to score and giving the Pirates a thrilling 12-8 victory.

Clemente's hit was not only a testament to his skill as a hitter but also to the circumstances that had to align for such a play to occur. An inside-the-park grand slam requires a combination of power, speed, and a bit of luck, as the ball must stay in play while all runners must successfully circle the bases without being thrown out.

Roberto Clemente is remembered for his extraordinary career with the Pittsburgh Pirates, spanning from 1955 to 1972. He was a 15-time All-Star, 4-time National League batting champion, 12-time Gold Glove winner, and a World Series champion in 1960 and 1971. More importantly, Clemente was known for his humanitarian work off the field, which earned him the admiration of fans and fellow players alike. Sadly, his life was cut short in a plane crash on New Year's Eve in 1972, while he was en route to deliver aid to earthquake victims in Nicaragua.

Clemente's legacy endures, and his inside-the-park grand slam remains a unique and unforgettable moment in baseball history. It stands as a symbol of his incredible athletic ability and the indelible mark he left on the game.
