The Athletics signed right-hander Chris Ray and assigned him to Triple-A, Susan Slusser of the San Francisco Chronicle tweets. The Indians released Ray from their Triple-A team less than a week ago.
Ray posted a 2.75 ERA with 7.5 K/9 and 4.2 BB/9 in 36 innings of relief for Triple-A Columbus before being released. The 30-year-old posted a 4.68 ERA with 6.1 K/9, 3.3 BB/9 and a 46% ground ball rate in 32 2/3 innings for last year's Mariners team.
