New York Yankees owner, George Steinbrenner, died in a Tampa, Florida hospital on Tuesday morning (July 13) after suffering a massive heart attack.

The longtime owner, whose Yankees team won 11 American League pennants and seven world championships under his ownership, was 80 years old.

Steinbrenner's death comes just days after another Yankee legend, public-address announcer Bob Sheppard, died on Sunday at age 99.

The baseball team owner, who was referred to as "The Boss," bought the Yankess in 1973 from CBS for just $8.8 million, and over the years, turned it into a billion dollar organization and one of sports' most celebrated franchises.

He had a reputation for winning at-all-costs, spending markedly more than other teams to acquire the game's best players, and reportedly became involved in feuds with several of his star players over the years.

Still, Steinbrenner was respected. There was a moment of silence at the MLB All-Star game at Angel Stadium on Tuesday, where a tribute to the Yankees owner was played on the video board. Shortstop Derek Jeter and other members of the Yankees wore black armbands to honor their late team owner. And, the U.S., Canadian and state of California flags were lowered to half-staff.

According to reports, the Yankees will wear uniform patches for the rest of the season to remember Steinbrenner and longtime public address announcer Bob Sheppard. The patch for Steinbrenner will have his initials and include "The Boss," while the patch for Sheppard features a microphone.

Steinbrenner's health had been declining in recent years, and he had effectively turned over control of the team to his sons, Hal and Hank.

In a statement released, the family said funeral arrangements would be private, but a public service will be held at a later date.
