ST. PETERSBURG -- The Rays selected Johnny Field from Triple-A Durham on Friday. The corresponding move saw right-hander Ryan Weber get designated for assignment.
When a player's contract is designated for assignment -- often abbreviated "DFA" -- that player is immediately removed from his club's 40-man roster, and 25-man roster if he was on that as well. Within seven days of the transaction (it was previously 10 days), the player must either be traded, released or placed on irrevocable outright waivers.
"We need [Field] now," Rays manager Kevin Cash said.
