At one point, Dan Haren imagined himself wearing a Cubs uniform, pitching at Wrigley Field and spending this summer by Lake Michigan – at least until the trade deadline. Now Haren’s hoping to win a World Series ring with the Washington Nationals. Haren signed up for Twitter at the beginning of last offseason. He didn’t do it for marketing purposes. He wanted to follow all the fragments of information as the Los Angeles Angels decided what to do with his $15.5 million option, as well as get a sense for where he might land as a free agent. Haren had no idea he would be at the center of an Internet storm once Cubs closer Carlos Marmol told reporters in the Dominican Republic he was traded to the Angels. Standing in the middle of the home clubhouse at Nationals Park on Friday, Haren said he’s still not quite sure how the deal fell apart. “I guess everything happens for a reason,” Haren said, “and it worked out for me coming here, but I was sold on going to Chicago.” Haren, who has a home in Southern California, met with Angels general manager Jerry Dipoto in Anaheim a few days before the Nov. 2 deadline where the team had to pick up the option or buy it out for $3.5 million. Haren came away from that meeting feeling “100 percent” certain that he was going to be traded. He believed the Cubs were one of three or four teams showing interest and the Nationals were not part of that group. “From what (Marmol) had said, I thought I was traded,” Haren recalled. “It was all over the Internet. But when it was all going down, I texted Dipoto and I asked him if I had been traded. He said we’re still in the process, nothing’s official, things still have to work out…He never said for sure it was a done deal.” Leading up to the 9 p.m. West Coast deadline, Marmol had waived his limited no-trade rights and approved the deal. The Cubs were said to be willing to kick in more than $3 million, or less than half of Marmol’s $9.8 million salary on an expiring contract.
