I'd read the rumors last week about the Yankees' interest in Chan Ho Park, though I didn't think they'd actually bother to sign him. I'm not entirely sure what attracted the Yankees to Park, whose last stint in the AL was both half a decade ago and terrible.
Park seems to have reinvented himself as a somewhat serviceable reliever, posting an FIP of 3.49 for the Phillies last season, but I'm not sure Park brings anything to the table that the Yankees couldn't have gotten from an internal candidate.
Not that this has anything to do with anything, but Park pitched reasonably well against the Yanks in the 2009 World Series, notching three strikeouts in 3 1/3 scoreless innings over four appearances. I guess given the nominal amount of money ($1.3 million) and general volatility of relievers the Yanks hope they luck into a helpful bullpen piece.
