Kahnle (shoulder) may be activated from the IL during the Yankees' series against Seattle that begins Monday, per MLB.com.
Kahnle kicked off a minor-league rehab assignment May 8 and has been dominant through four outings, posting a 9:0 K:BB while tossing four perfect frames. The veteran reliever is slated to make another rehab appearance Saturday, after which he'll be re-evaluated. If Kahnle is cleared at that point, he could make his season debut for the big-league Yankees as soon as Monday.
