Famous Red Sox numbers: The stories behind 9, 34, 45 and more

A big name can bring value to a team, but only the greatest players in a franchise’s history are recognized by a number.

The Red Sox have retired the numbers of a few legends, including Ted Williams, David Ortiz and Pedro Martinez. Those numbers sit on the right field facade at Fenway Park, honoring the organization’s most impressive figures.

Here’s a breakdown of some of the most iconic numbers in Boston Red Sox history.

The Red Sox’s most iconic numbers and who made them famous

Bobby Doerr (1) set several team records and was an elite second baseman.

Carl Yastrzemski (8) was an 18-time All-Star and AL MVP. He had over 3,400 hits and 450 home runs in his career.

One of the most significant figures in Red Sox history, Ted Williams (9) was a 19-time All-Star and two-time AL MVP. He was the last player to ever hit over .400 for a full season.

While the number has not yet been retired, Jason Varitek (33) could be honored down the road. The World Series-winning catcher was a consistent leader as the captain of the Red Sox.

David Ortiz (34) was a feared hitter and 10-time All-Star, producing in the postseason when it mattered most. He helped the Red Sox win multiple World Series rings following years of frustration.

Pedro Martinez (45) is considered one of the most dominant pitchers in Red Sox history. The three-time Cy Young winner accomplished the rare feat of the pitching Triple Crown in 1999.

Modern Red Sox players wearing legacy numbers (and the pressure)

While some numbers get recirculated, it’s not easy to live up to the legacy of elite players who haven’t had their numbers retired.

Alex Bregman recently wore the No. 2 jersey, previously worn by player and broadcaster Jerry Remy and former Red Sox player Xander Bogaerts.

Vaughn Grissom wore No. 5 until being traded in the 2025 offseason. The number previously belonged to Nomar Garciaparra, a beloved figure in Boston. There has been some speculation that Garciaparra could see his number retired in the future.
