ORIGINAL: The New York Yankees have claimed White Sox closer David Roberston from revocable waivers, according to Jon Heyman of CBS Sports. A deal between the two teams before day's end appears unlikely. Instead, the White Sox will likely pull him back off of waivers.

While the Yankees have indeed won the claim, sources say, it's now up to White Sox to decide if they would consider trading Robertson or -- less likely – even letting him go to the Yankees. At this point, though, there isn't strong evidence to suggest the White Sox have any intention to let Robertson leave by any means.

The 30-year-old spent his entire career with the Yankees before departing as a free agent after the 2014 season. He signed a four year, $46 million contract with the White Sox. In his place, the Yankees brought in Andrew Miller on a four year, $36 million contract.

This year with the White Sox, Robertson has payed off so far. In 52 innings, Robertson has a 2.60 ERA with a 12.2 K/9, 1.9 BB/9 and 27 saves. Robertson is owed an additional $36 million through 2018. Heyman indicated that the claim on Roberston happened on Saturday afternoon.

The Yankees have been intrigued by bring in an elite reliever to join their duo of Miller and Dellin Betances. General manager Brian Cashman showed strong interest in Craig Kimbrel and Aroldis Chapman before the July 31 trade deadline.

For the deal to be worthwhile for the Yankees, they would need to acquire Robertson before the day's end so he could be eligible for the Yankees' post season roster.
