Johnny Joestar (ジョニィ・ジョースター Jonī Jōsutā), originally San Diego Beach - September 23, 1890 - 2 Days to Start, Part 3 (サンディエゴビーチ 1890年9月23日 スタート2日前 その③ San Diego Bīchi Sen-happyaku-kyūjū-nen Ku-gatsu Nijūsan-nichi Sutāto Futsuka Mae Sono 3) in the WSJ release, is the third chapter of Steel Ball Run and the seven hundred fifty-fifth chapter of the JoJo's Bizarre Adventure manga.
The chapter opens with Johnny reflecting on his reason for coming to the San Diego beach start line, on his youth as a new horse racer, and his rise to fame. He was 5 years old when he first rode, describing a "beauty" that resides in it. Acknowledged by his father, he had acquired some fame before 16 years, earning the nicknames "JoJo" and "Joe Kid." He won the Kentucky Derby at 16, stating that he was unrivaled in his talent and had easy success with women.
He recalls going to a play with a girl he was dating at the time, and taking her advice to cut to the front of the line. A nervous man there contests him, upon which Johnny bribes two doormen to remove him. The man soon retured and shot Johnny in the back, incapacitating him. Johnny awakened in a dark hospital room where he sees blood being taken from his leg by an orderly, who tells him neither his father nor any of his supposed friends have come to see him. Johnny cried out as he realizes that he has been abandoned, but the orderly stuffs a newspaper in his mouth to stop him from waking the other patients in the room, reading the headline "Steel Ball Run Race: Projected start in two years."
Johnny is amazed as he stands and then falls back into his wheelchair. Gyro leaves, and Johnny desperately pursues him, demanding explanation. Gyro tells him that it was a simple reflex; but, reaching out, just as Johnny again touches a Steel Ball, his arm twists, and he is hung at his fingers on a nearby rafter. Johnny resolves to discover the truth of this "Spin" and to enter the race in Gyro's pursuit.
