The Rangers officially announced the signing of free-agent outfielder Shin-Soo Choo at an introductory news conference at the Ballpark in Arlington on Friday. "Today is a very special day for me and my family," Choo said. "Thirteen years ago, I was 18. A kid. I didn't know anything. Just came here, just playing baseball, really working hard. Today is my dream come true. My next dream is to win a World Series ring." Choo agreed to a seven-year, $130 million contract with the Rangers on Saturday. Choo passed his physical on Tuesday but the announcement was held up by Christmas and club officials had been unavailable. "We use the term 'good fit' a lot when we're looking at players to add in," general manager Jon Daniels said on Friday. "I think in this case it was the perfect fit. His skill set, his personality, his personal goals and desires really line up perfectly with us and what our club needed. He's really been one of the most productive offensive players in the game for a period of time now." "He's extremely driven and really a perfect fit for what we're doing." Rangers manager Ron Washington said Choo will be the club's regular left fielder, though he plans to take advantage of Choo's experience in center and right as well. "My intention is for Choo to be my leadoff hitter, but what Choo brings is versatility," Washington said. "There may be a time where I need him to hit in the middle of the lineup. There may be a time where I need him to hit down in the order. "He's a young man that's bringing old-school values, and that's what I like the most."
