Did barry bonds hold the record for thevbmost homeruns in a season?

Yes, Barry Bonds holds the record for the most home runs in a single season, with 73 home runs in 2001. This record surpassed the previous mark of 70 home runs set by Mark McGwire in 1998. Bonds' achievement has been a subject of controversy, largely due to allegations of performance-enhancing drug use during his career.
