Devenski was placed on the 60-day injured list Saturday with a sprained UCL in his right elbow.
The 30-year-old last pitched Thursday against the Marlins and surrendered two runs on four hits over two-thirds of an inning. Devenski will now be sidelined for at least the next two months while on the 60-day IL, though given it's a UCL injury, a longer absence wouldn't be surprising.
