It is likely that the White Sox would receive an impressive number of prospects in return for Quintana, although it is not likely they would be the same as Chicago received in its trade for Sale.
MLB Trade Rumors have been popping up about the Chicago White Sox all off season. There have also been a ton of MLB Trade Rumors surrounding left-handed starting pitcher Jose Quintana. They could flip Robertson or move Betances as the next part of this complicated deal, but maybe the Yankees could give themselves an expensive boost to their pitching staff altogether.
Per Bob Nightengale of USA Today, the Yankees have "expanded" discussions with Chicago to try and add Robertson into any trade deal that might get done, as NY seeks to improve both the starting rotation and bullpen heading into 2017.
Quintana is the pitcher of every team's dreams and going by the lack of stability in New York's rotation, he may just be the missing link to a true contender. The team could certainly use another starting pitcher but don't want to overpay to acquire one.
Could trade talks between the New York Yankees and Chicago White Sox result in reliever David Robertson heading back to the Bronx? This shouldn't be a problem for the White Sox if they're able to get a top prospect or two from the Yankees in exchange for Quintana and Robertson.
However, Robertson is still a strong back of the bullpen arm who could be enticing on the trade market.
However, it is interesting the Yankees are interested in acquiring its former closer in Robertson. The Yankees already added payroll by signing free agent outfielder Matt Holliday and re-signing closer Aroldis Chapman to the biggest contract a closer has received in Major League Baseball.
However, if the rebuilding White Sox can get a top-tier prospect like Frazier or Torres, I imagine that they will gladly pay a chunk of Robertson's deal. But the fact that these trade talks have not only remained intact, but have actually expanded, leaves reason to believe something could legitimately be in the works, and the Yankees may soon be closer to contending for a 28th World Series championship than previously thought.
