Ryan Dunne, played by Freddie Prinze Jr., is a dedicated local baseball player with aspirations to make it to the Major Leagues. Balancing his time between helping his father with their landscaping business and maintaining Veteran's Field, home to his team, the Chatham A's, Ryan faces financial challenges. As summer unfolds, the town buzzes with young hopefuls eager to showcase their skills to big-league scouts, including talents like Billy Brubaker (Matthew Lillard), Mickey Dominguez (Wilmer Valderrama), and Miles Dalrymple (Marc Blucas).
Determined to secure a spot in the pros, Ryan has made a commitment to abstain from distractions such as romance and partying. Under the strict coaching of Coach John Schiffner (Brian Dennehy), who has little tolerance for Ryan's laid-back attitude and frequent tardiness caused by previous late-night outings, he must step up his game. Everything shifts when Ryan encounters the captivating Tenley Parrish, portrayed by Jessica Biel, while assisting his father with lawn care for the Parrish family, who spends summers in Cape Cod. Tenley, the affluent and stunning daughter, takes a keen interest in Ryan, complicating his focus.
Ryan's life further intertwines with the Parrish family, as his bond with Tenley grows stronger, much to the delight of her younger sister Katie, a big fan of Ryan. Mickey finds himself in an awkward situation when his lusty house mother, played by Beverly D'Angelo, takes a fancy to him, causing his friends to encourage him to pursue her.
Ryan's brother, Mike Dunne (Jason Gedrick), lives with the burden of being a failed ballplayer and is always hard on Ryan, lamenting that he's wasting his natural talent. He accuses Ryan of wallowing in self-pity since their mother's passing. During the A's season opener, Ryan's responsibility is to solicit donations from the crowd, and a rivalry emerges when opposing pitcher Van Leemer (Corey Pearson) delivers an outstanding performance. Ryan's spirits lift when he shares a romantic first kiss with Tenley later that evening.
As the season progresses, Ryan encounters the pressures of expectations from his family, friends, and scouts. An emotional turmoil ensues when he discovers Tenley’s previous relationship with a man favored by her father, suggesting that Ryan may merely be a summer fling. Despite a promising start to the game, Ryan unravels under pressure when he allows a grand slam, leading to a disappointing loss. Although he faces demotion to the bullpen, a scout named Hugh Alexander (John C. McGinley) still recognizes Ryan's potential.
Encouraged by his friends, he refuses to succumb to self-pity. However, when Rand, Tenley’s father, threatens to withdraw business from Ryan’s father unless he stops seeing Tenley, Ryan finds himself in a heartbreaking dilemma. He ultimately tells Tenley to take her dream job in San Francisco, believing it’s best for her future.
With pressure mounting, a series of tumultuous events leads to Ryan earning the chance to start a pivotal final game of the season. On the eve of this crucial moment, Tenley reveals her imminent departure for San Francisco, advising Ryan to seize his potential. In a transformative performance, Ryan pitches a no-hitter that wows everyone, including scouts and family.
In a heartfelt last-minute chase, Ryan rushes to the airport and confesses his love to Tenley, convincing her to stay in Cape Cod instead of leaving for the job opportunity. Their reunion culminates in a joyful embrace, representing a turning point both personally and professionally. With his family and Hugh Alexander supporting him, Ryan finally receives an offer to join the Phillies' minor league affiliate.
As the narrative unfolds, we witness Ryan's Major League debut wherein he faces the renowned Ken Griffey Jr., who hits his inaugural pitch out of the park. The journey, filled with challenges and triumphs, ultimately showcases Ryan's dedication, love, and the unwavering support of those around him.
