Mariners' Tom Wilhelmsen: Could go on DL with back ailment

Wilhelmsen could be placed on the disabled list Saturday because of back soreness, the Seattle Times reports.

Analysis:

Wilhelmsen gave up four runs in a third of a inning last Sunday and then was given a few days off because of a sore back. He pitched a scoreless inning Thursday, but was bothered by the back again Friday. Prior to his four-run implosion, Wilhelmsen had allowed three runs in 20 appearances (18.1 innings) since joining the Mariners on June 22 with a .197 BAA.
