Burriss, the Giants' 2006 first-round Draft pick, has batted .214 in 131 at-bats this season in 52 games and has a .243 career average since being called up in '08.
"The emotions are kind of high only because I've been here since I was drafted," Burriss said. "The one thing I learned since I've been here is that this is a big business. They have to make the move, and I completely understand. Honestly, it looks like it's the best fit for the team."
Burriss said he remains open to returning to the Giants but that his first priority is finding more playing time with another club, and Giants manager Bruce Bochy said he expects a move to be made within the next few days, hoping to find a better opportunity for the 27-year-old infielder.
"Obviously that's why this could be a pretty good opportunity for him," Bochy said. "I know his playing time has been cut down, and really that was a case of how well [Ryan] Theriot has been playing. What he needs now is a chance to show what he can do, and maybe another club will have something for him, and if they do, I'd be happy for him to have that opportunity."
