Superagent Scott Boras does some of his finest work in the latter stages of free agency. And in the case of Shin-Soo Choo, he faces yet another challenge in a career built on slaying them: find Choo a contract for the $140 million the New York Yankees offered him even after they signed Jacoby Ellsbury.

In the aftermath of Robinson Cano's defection to Seattle, New York presented Choo a seven-year, $140 million deal, three sources outside the Yankees' organization told Yahoo Sports. When Boras countered asking for more money – one source indicated he wanted "Ellsbury money," or $153 million over seven years – the Yankees pulled the offer and signed Carlos Beltran to a three-year, $45 million deal.

Asked to confirm the Choo offer, Yankees officials declined comment. Their recusal from the Choo sweepstakes took one big-money team out, and sources told Yahoo Sports on Tuesday that the Texas Rangers have shifted their focus to Japanese starter Masahiro Tanaka, whom most officials in baseball expect to be posted by his team in Japan. Other teams may do the same in an effort to drawn down Choo's price tag, though if there is a truth about Boras, it's that he usually gets his money.
