The Athletics on Tuesday placed Huston Street on the 15-day disabled list with irritation in his right ulnar nerve. The move is retroactive to Sunday, a day after Street tossed a scoreless relief frame against the Indians. Street is 2-1 with a 2.50 ERA in 18 relief appearances and has recorded all nine of Oakland's saves this year. He had allowed just two runs over his last 13 outings for a 1.35 ERA and has not yielded a run in 15 of his 18 outings this year. It marks the second career DL stint for Street, who was sidelined from August 19 to September 8 last season with a strained right groin.
