The move fills the 40-man roster to capacity.
The deadline for clubs to add players to the 40-man roster is Friday, and these moves ensure none of those six guys can be picked up in the Rule 5 Draft in December -- unless they are outrighted at a later date.
Some notable prospects who were not protected and could be picked up include right-handers Steven Johnson and James Hoey, second basemen Ryan Adams and Miguel Abreu, and shortstop Blake Davis. Players picked up in the Rule 5 Draft must be placed on the 25-man roster or offered back to their previous clubs for $25,000 -- half the drafting price.
Bell, Snyder and Erbe are currently playing for the Arizona Fall League's Phoenix Desert Dogs.
Bell batted .275 with 20 home runs and 76 RBIs in 127 games with the Dodgers' and Orioles' Double-A affiliates. The 23-year-old came over in the deal that sent reliever George Sherrill to the Dodgers before the non-waiver Trade Deadline.
The 22-year-old Snyder, the O's first-round Draft pick in '05, batted .289 with 37 doubles, 12 homers and 88 RBIs in 131 games between Double-A Bowie and Triple-A Norfolk this past season.
Erbe, 21, went 5-4 with a 2.70 ERA in 18 starts between rookie-level Aberdeen and Double-A Bowie.
Lebron, meanwhile, had 20 saves and a 2.54 ERA in 52 games between Class A Frederick and Double-A Bowie. The 24-year-old was signed as a non-drafted free agent in '04.
Florimon, 22, batted .267 with nine home runs and 68 RBIs in 115 games for Class A Frederick. He was also the starting shortstop in the 2009 Carolina League All-Star Game.
Lastly, the 25-year-old Hughes -- acquired in the deal that sent catcher Gregg Zaun to the Rays in August -- batted .279 with 25 homers and 79 RBIs in 134 games between Triple-A Norfolk and Durham and Double-A Montgomery this past season.
