The Phillies claimed Tarnok (hip) off waivers from Oakland on Saturday. The Phillies reinstated him from the 60-day injured list and optioned him to Triple-A Lehigh Valley.
Tarnok has been on the injured list all season while recovering from a hip procedure he underwent in August. He began a rehab assignment with Triple-A Las Vegas on May 8 and allowed 11 earned runs in just 7.1 innings before Oakland removed him from its 40-man roster. He'll remain in Triple-A upon making a full recovery and shifting to a new organization, though a drastic turnaround in performance would likely be necessary before Tarnok spends any time in Philadelphia. Dylan Covey (shoulder) was transferred from the 15-day IL to the 60-day IL to open up a spot on the 40-man roster for Tarnok.
