""Siebert Honor Book author Alonso highlights not only Valenzuela's impressive career but the positive impact he had on Latino Angelenos, who loved seeing a Mexican player who felt like one of them. Illustrated with Parra's bright, blocky artwork, the book focuses mainly on Valenzuela’s rookie year and fittingly concludes with a World Series Game against the Yankees. An informative, visually engaging picture book for baseball fans.""—Booklist ★“Beautifully presented, written with deep admiration; recommended for elementary libraries, especially where baseball is popular.”—School Library Journal, starred review
