Santos (biceps) fired two-thirds scoreless innings in Triple-A Tacoma's loss to Oklahoma City on Sunday, issuing two walks and recording a strikeout.
Santos made his second rehab appearance in three days for the Rainiers and bounced back from having allowed a run over two-thirds of an inning in Friday's outing. The right-hander threw another 18 pitches Sunday, although only seven landed for strikes. Santos has exhibited control issues in each of his last two appearances, but from a workload standpoint, he certainly seems to be ready for activation.
