The Dodgers held a news conference to introduce Ryu on Monday, the day after signing him to a six-year, $36 million contract. As part of Ryu's contract, the Dodgers will not be able to demote the 25-year-old to the minor leagues if he struggles. Needless to say, the Dodgers have options, including flexibility to move a couple pieces around to fill other needs, or even to place Ryu in the bullpen initially to help ease his transition to MLB. Ryu, 25, pitched seven years in the Korean Baseball Organization, where he had a 2.80 ERA and 1,238 strikeouts in 1,269 innings. Ryu will appear in the front plaza at Wilshire Park Place/Radio Korea Building, 3700 Wilshire Boulevard, from noon to 1 p.m. PT. That would work out just fine for the Dodgers, who also anounced Monday night they have signed former Cy Young winner Zack Greinke to a six-year, $147 million deal. The former Korean league star set some lofty goals for himself entering his first season in the major leagues: double digit wins, a two-something ERA and eventually eclipsing Chan Ho Park's record 124 victories for a Korean pitcher.
