The White Sox are the latest team to express interest in closer David Robertson, George A. King III of the New York Post reports. “They like him a lot and he is definitely on their radar,’’ a source tells King. “They have several things they want to do and he is one of them.”

Robertson is looking for a contract in the four-year, $50MM range and the Sox are reportedly “aren’t blanching” over the idea of giving the closer that big a guarantee, King writes. Chicago’s first round pick (eighth overall) is protected, so they’d only have to give up their second-rounder as compensation to sign Robertson, who rejected the Yankees’ qualifying offer. Robertson would provide a major boost to a White Sox bullpen that posted a cumulative 4.38 ERA in 2014, the third-highest mark in baseball.

The Astros, Blue Jays and Yankees are three of at least a half-dozen clubs who have shown interest in Robertson, though King cites reasons why all three could bow out of the race. The Jays may not be willing to meet Robertson’s asking price, the Astros “don’t believe Robertson wants to pitch for them” and the Yankees would prefer to give their former stopper a deal closer to the $40MM threshold. New York had also been hesitant to give Robertson more than three guaranteed years, though the team “may be softening” in that respect.
