Mariners put RP Joe Beimel on DL, promote RP Rob Rasmussen

The Mariners have placed reliever Joe Beimel on the disabled list with arm fatigue and promoted fellow left-hander Rob Rasmussen from Triple-A Tacoma, per the Tacoma News-Tribune.

Beimel has complained about the ailment lately - and he has evidence to prove it. He has allowed an outrageous 10 earned runs and five home runs over his last 1 2/3 innings to send his ERA soaring from 2.50 to 4.78.

Rasmussen was just sent down by Seattle on Monday after compiling an awful 14.09 ERA.
