Without the efforts and vision of Reid Ryan, there would be no Round Rock Express. Ryan served as the founder and original CEO of Ryan Sanders Baseball, the ownership group o the Express, leading the charge in acquiring the Jackson Generals franchise and relocating the club to Round Rock to become the Express in 2000.

As the team’s CEO, Ryan’s top priority was the fan experience, and he quickly became a fan favorite for his ability to connect with people. Since the team’s founding, the Express have been perennially lauded as one of the top franchises in Minor League attendance, stadium satisfaction and franchise value.

Ryan oversaw the club’s transition from the Double-A Texas League into the Triple-A Pacific Coast League in 2005. After 13 prosperous seasons leading the E-Train, Ryan was named the President of Business Operations for the Houston Astros in 2013. In 2018, the Express rejoined the Astros family as the club’s Triple-A affiliate, bringing the franchise Ryan founded back into his domain.

In 2004, the lefty slashed .298/.401/.654 with 17 doubles and 19 home runs in only 63 games.
