premise: They had until midnight on Thursday to reach a contract agreement with Igawa, who otherwise would have returned to his Japanese club, the Hanshin Tigers.
  Igawa will likely join a starting rotation which already includes Mike Mussina, Andy Pettitte, Chien-Ming Wang and Carl Pavano. The Yankees reportedly are looking to trade 43-year-old lefthander Randy Johnson, who has underachieved in his two seasons in New York.
  Igawa went 14-9 with a 2.97 ERA for the Tigers last season. He recorded 197 strikeouts to lead the Central League in strikeouts for the third time in eight seasons.
   What would have happened had The Yankees not reached a contract agreement with Igawa?
hypothesis: has underachieved in his two seasons in New York
