"As anyone can plainly see, I'm 5-6; and a strapping 150, and unlike some people, I came by all of it naturally," Costas said Thursday in a telephone interview.
On this week's edition of HBO's "Costas Now," commissioner Bud Selig, Boston Red Sox pitcher Curt Schilling and chemist Patrick Arnold discussed Bonds, his pursuit of Hank Aaron's home run record and suspicions that Bonds has used steroids. Schilling and Arnold said they believed Bonds had taken performance-enhancing drugs.
Bonds viewed at least part of the show before Wednesday's game against Atlanta.
"I've actually always had a pretty cordial relationship with Barry," Costas said. "I have no ill feelings toward him personally. I regard him as one of the greatest players of all time who got inauthentic boost and then became a superhuman player. I wish him no ill whatsoever."
Costas said he understood why Bonds might have denigrated him.
"He's under tremendous scrutiny and some pressure. It's no big deal," Costas said. "This is a consequence of doing your job, and I've never tried to do my job in any case with the intention of calling attention to myself. I think if people watch the program, they can judge for themselves."
