The Seattle Mariners bolstered their bullpen by acquiring right-hander Arquimedes Caminero from Pittsburgh and switch-pitcher Pat Venditte from Toronto in a pair of trades Saturday.

Both deals Seattle made were for players to be named later. Seattle will be sending two players to Pittsburgh for Caminero and one to Toronto for Venditte. The Mariners announced Venditte would report to Triple-A Tacoma, while Caminero will report to Seattle.
