20-Year-Old Founder Buys Wiffle Ball Brand

Logan Rose, a 20-year-old sophomore at Southern Methodist University, now owns the company that manufactured the perforated plastic balls and yellow bats used in backyard baseball for decades. In October, he and his family purchased The Wiffle Ball Inc. from the Mullany family, who had held the trademark since David N. Mullany founded the business in 1953. The Mullanys decided to sell after managing the 73-year-old Connecticut-based brand for many years.

The purchase gives the Rose family control over both the manufacturing business and the league they started. Logan serves as CEO, while his 17-year-old brother, Carson, acts as chief growth officer. The two brothers plan to stabilize the company while expanding the sport. They intend to keep the league and the manufacturing entity independent, but both will work toward the shared goal of growing Wiffle ball participation across different cities and age groups.

Logan started the league in 2020 while he was 13 years old. He organized games in his Scottsdale, Arizona backyard to combat boredom during the early days of the pandemic. He scheduled matches, communicated with players, and launched a tournament that same year. The informal competitions evolved into Big League Wiffle Ball. Logan said the process was not initially complex, but it taught him how to manage a small operation.

His father, Luke Rose, noted that Logan spent hours editing video content for the league, even when the audience was small. This dedication helped the family grow the sport from a local hobby into a competitive circuit. The family now hosts the Western Wiffle Ball Classic at Scottsdale Stadium, a spring training site for the San Francisco Giants. The event has grown from about 20 teams in its early years to approximately 45 teams in the most recent edition.

Carson Rose, who has played with Wiffle balls since toddlerhood, said the family had to build interest in a region with little history in the sport. They partnered with actor Kevin Costner for the 2025 event, screening the movie Field of Dreams. For the 2026 classic, the family added a Home Run Derby to encourage competitive play. Carson said the derby motivates participants to qualify against professional players like Shane Doan.

The acquisition allows the family to hold the intellectual property for the league. Carson stated that no other sport in the world has this specific structure, which he believes will benefit the organization. Logan described the league as the highest level of the sport and said there is substantial room for growth in the actual game of Wiffle ball.
