Chad's got the summertime blues: his parents want him to be home by midnight (no extra innings) and eat healthier (no corn dogs). His friend, Abby, has bobblehead issues. And then there's pinch hitter Sammy Solaris. But Sammy has problems of his own. He has a big swing but is too slow. If he can't speed up his running and stealing, he'll be off the team. There's got to be something Chad can do to save the day . . . with a little help from Dylan, a baseball card, and that porcupine!
