Via Bryan Hoch, the Yankees have activated Chan Ho Park from the 15-day DL after he battled a bum hamstring for the last month. Ivan Nova has been sent to Triple-A Scranton to make room on the roster. Getting CHoP back is big right now, given the unreliably of the middle relievers beyond Joba Chamberlain and Mariano Rivera (yesterday notwithstanding). Furthermore, David Robertson and Joba respectively threw 30 and 23 high stress pitches yesterday, so they might not even be available tonight. Park might get thrown right into the fire.
