Zero's Slider (Hardcover, Turtleback School & Library ed.)

The Peach Street Mudders are in trouble: they need to find a substitute coach quick. Pitcher Zero Ford would love to ask his uncle Pete to step in, but after his poor performance on the mound, he doubts his uncle would be interested. Then Zero injures his finger -- and finds he can throw an amazing pitch that stumps every batter he faces! The question is, When the bandage comes off, will the slider -- and Uncle Pete -- disappear?
