While all his friends from the present and future are in Metropolis celebrating Superman Day, the date of Superman's arrival on Earth, the Man of Steel lay dying from exposure to a chunk of Green Kryptonite—courtesy of an anniversary present from the warped mind of Bizarro Number One.
As the stricken Man of Tomorrow lay helpless, he combs the festivities with his X-Ray vision to see which one of his friends will save him—prophetically one with the initials L.L as foretold by a gift, "...an advanced kind of computer!" from the Cybern Galaxy.
As his life ebbs away Superman is suddenly saved by a young lad playing baseball who is wearing a uniform. Surprisingly, Superman's rescuer's name, Steven Snapinn, doesn't have the initials L.L. Then, Superman sees the lettering on the back of his savior's uniform—that he was, in fact, a Little Leaguer (S No. 157/3, Nov 1962: "Superman's Day of Doom").
