The Rangers and Yu Darvish reached an agreement on a six-year, $60 million contract on Wednesday. The right-hander's father, Farsad, is preaching patience with his son as he begins his Major League career. Darvish is scheduled to come to Texas on Friday for a news conference at Rangers Ballpark in Arlington. Farsad is confident his son will succeed, but hopes fans can be patient while he adjusts to life in the big leagues and in Texas. "The next six months of transition is important," Farsad Darvish said. "I feel responsible because the team has invested a lot of money and we have to make sure whatever the team asks us to do that can help Yu that we try to do it to help things go well. That's important. "You are talking about [a] different culture. It would be nice to give it a little time and don't judge things so fast. I know Yu will find his way. I think the fans are looking forward to the team getting another chance at the World Series, and I really hope Yu can be a member when they get there."
