What book did Maniac give Grayson for Christmas?

Maniac gave Grayson a hand-made book on Christmas. The book was titled The Man Who Struck Out Willie Mays.
On Christmas morning, Maniac and Grayson enjoyed tea, cookies, and eggnog for breakfast. They sang carols and exchanged gifts. Maniac gave Grayson a pair of gloves, a woolen cap, and a hand-made book. The cover of the book was made out of blue construction paper, and the spine was kept together by staples. Maniac had personally hand-written all of the script and hand-drawn the stick figures in the book.
As for Grayson, he presented Maniac with a pair of gloves, a box of butterscotch Krimpets, and a new baseball. However, the best present was saved for last: Grayson's old Minor League leather baseball gloves. Although the leather was cracked, Maniac could not take his eyes off the gloves. To Maniac, the present made the Christmas celebrations meaningful to him. Sadly, however, Grayson died five days after Christmas.
