[3] In 1965, Moreno graduated from high school and in 1966, he was drafted into the United States Army and fought in the Vietnam War.

He traveled across the country for the next seven years, relocating several times and in 1984, he moved back to Arizona, settling in Phoenix, where he was hired by billboard company Outdoor Systems.

In 1984, Moreno and his friend Wally Kelly attempted unsuccessfully to buy the firm from owner William S. Levine.

With baseball being Moreno's favorite pastime, he purchased the Salt Lake Trappers minor league team alongside 17 other investors in 1986.

He nonetheless remained determined to own a Major League team, and soon set his sights on the 2002 World Series champion Anaheim Angels.

Moreno soon demonstrated a willingness to spend the money necessary to sign premium players, including star outfielder Vladimir Guerrero.

In recent years, the San Diego Zoo and Los Angeles Times have been notable club sponsors, while all baseball TV rightsholders also use some variation of the team's new name, indicating the effect of Moreno's plan.

In October 2020, Moreno, through his company SRB Management, agreed to purchase Angel Stadium and the surrounding parking lots from the City of Anaheim for $320 million.

In May 2022, it was reported that an FBI had conducted a corruption investigation into the dealings of the city and the stadium sale, which led to the resignation of Anaheim mayor Harry Sidhu on May 24.

[14] In his tenure, the Angels had a run of sustained consistency in the mid to late 2000s that included five American League West championships from 2004 to 2009.

After failing to reach the World Series each time, they missed the postseason until 2014, two years after having signed Albert Pujols to a record 10-year deal for $254 million that outbid the St. Louis Cardinals.

The eight losing seasons, all under Moreno's leadership as owner, is the worst stretch in Angels history, eclipsing the 1971-1977 era.

He has been criticized for targeting mega-contracts that quickly became problematic -- particularly those of Vernon Wells, Albert Pujols, Josh Hamilton and Anthony Rendon, the latter three of which came with the loss of draft picks -- and then declining to exceed the luxury tax threshold in an effort to make up for it.

And he has been criticized for continually cutting costs in many of the behind-the-scenes aspects that would help maximize expensive rosters, from analytics to training resources to staffing hires -- an approach one former pitcher described as "buying a McLaren and taking it to Jiffy Lube".

Following the Dodgers victory in the 2024 World Series, criticism of Moreno increased from Angels fans who felt the team could have made a playoff run with Trout and Ohtani.
