Kittredge (neck) threw a bullpen session Saturday and manager Kevin Cash noted afterwards that the reliever's stiffness was "pretty much gone," the team's official site reports.
The right-hander was put on the injured list retroactive to Sept. 18 as a largely precautionary measure, as the Rays were intent on not having him pitch through any discomfort and worsen a relatively minor issue. That strategy seems to be paying off as the season enters its final week, and it appears Kittredge, who's posted an excellent 1.55 ERA over 54 appearances, will be at full health for the postseason. Expect Tampa Bay to activate Kittredge from the injured list within the next couple of days.
