BOSTON — The longest home sellout streak in major pro sports history ended Wednesday night at 820 games for the Boston Red Sox.

The official attendance for an 8-5 loss to the Baltimore Orioles was 30,862. The capacity for night games at Fenway Park is 37,493.

The streak began in May 2003 and includes the postseason. The string broke the record of 814 set by the NBA’s Portland Trail Blazers from 1977-95.

Boston’s streak of 794 regular-season sellouts also is the longest in major pro sports history. The previous mark in Major League Baseball history was 455 set by the Cleveland Indians from 1995-2001.

“The streak is a reflection of a phenomenal period of baseball in Boston and of America’s greatest ballpark,” Red Sox owner John W. Henry said in a statement. “But more than that, it is a testament to the baseball passion of New England fans. As we close the book on this incredible era, we look forward to another with a renewed certainty that the next couple of generations of Red Sox fans will also be enjoying baseball at the ever magical Fenway Park.”

The sellout streak began on May 15, 2003, when the Red Sox beat the Texas Rangers 12-3.
