The Mariners could get left-hander Erik Bedard back by the end of the month.

Bedard threw a 30-pitch simulated game on Wednesday in Baltimore.

"He'll throw one more sim game in Oakland on Monday or Tuesday and probably stretch that out to 40-45 pitches," manager Don Wakamatsu said. "He had no problems."
