Ted Williams wore the number 9 for the Boston Red Sox.
As of my last update, the most notable player to wear number 98 for the Boston Red Sox is pitcher Ryan Brasier. He wore this number during his time with the team, which began in 2018. Additionally, other players like J.J. Hoover and Craig Kimbrel also wore number 98 during their tenures with the Red Sox, but Brasier is the most recognized for that number in recent seasons.
Luis Aparicio wore #11 with the Boston Red Sox.
Crisp wore # 10 with the Red Sox.
Most recently, Marco Scutaro
Terry Forster
Paul Konerko
