The Rangers have until Wednesday afternoon to strike a deal with Japanese right-hander Yu Darvish. A report over the weekend claimed that the length of the contract is the main sticking point, with Darvish preferring a shorter deal so he can hit the free agent market sooner. Rangers CEO Nolan Ryan reiterated over the weekend that he's "optimistic" a deal will get done by the 5 p.m. ET deadline. If for some reason things don't come together, Darvish would return to pitch in Japan in 2012 and the Hokkaido Nippon-Ham Fighters would have to refund the Rangers' record $51.7 million posting bid.
