Change-up: Mystery at the World Series (The Sports Beat #4)

"New York Times" bestselling sportswriter John Feinstein takes readers behind the scenes at the World Series in this exciting baseball mystery.
When teen sports reporters Stevie and Susan Carol are sent to cover the World Series, the talk of the tournament is Norbert Doyle--a late call-up for an underdog team. But the more they learn about him, the more conflicting stories they hear. Bit by bit they piece together the shocking truth about this rising star, but once the secret's out, there's no going back. . . .
John Feinstein has been praised as "the best writer of sports books in America today" ("The Boston Globe"), and he proves it again in this fast-paced novel.
