In the video, a baseball player is seen walking on the field. He is wearing a blue and green jersey with the word "SEIBU" written on it. The player is also wearing a blue cap with a white "L" on it. He is walking past a group of people who are standing behind him. The player is holding a baseball in his hand and appears to be preparing to throw it. The field is well-maintained, and the stadium is filled with spectators. The player seems focused and determined as he walks towards the pitcher's mound.
