David Glass is a former CEO of Walmart who also had a successful career in baseball. He purchased the Kansas City Royals in 2000 and served as the team's owner until 2019. During his tenure, the Royals experienced both highs and lows, including a World Series championship in 2015.

Glass was known for his commitment to building a winning team and investing in player development. He oversaw the construction of a new training facility in the Dominican Republic and invested heavily in the team's scouting and analytics departments. Under his leadership, the Royals developed a reputation for finding and developing young talent, including players like Eric Hosmer, Mike Moustakas, and Salvador Perez.

Despite his commitment to building a winning team, Glass was also criticized for his frugality. The Royals consistently ranked near the bottom of the league in payroll, and Glass was accused of not spending enough money to keep the team competitive. However, he defended his approach, arguing that the team needed to be financially responsible in order to sustain long-term success.

In 2015, Glass's commitment to building a winning team paid off when the Royals won the World Series. The team's success was a testament to Glass's leadership and his commitment to investing in player development. However, the team struggled in the years that followed, and Glass's frugality came under renewed scrutiny.

In 2019, Glass announced that he was selling the Royals to a group of local investors. His tenure as owner of the team was marked by both successes and challenges, but his commitment to building a winning team and investing in player development will be remembered as a key part of the team's history.
