The Rangers will formally introduce Yu Darvish at a press conference Friday night in Texas. Darvish agreed to a six-year, $60 million contract with the Rangers on Wednesday afternoon, about a month after the team put up a record $51,703,411 posting fee for his exclusive negotiating rights. The 25-year-old Japanese right-hander speaks a bit of English, so he may say some words at the 7 p.m. ET presser. He carries ace potential here in the states.
