The Pittsburgh Pirates have "worked hard" to complete a trade with the Chicago White Sox for Jose Quintana, according to a report.

The White Sox are rebuilding this offseason having dealt Chris Sale and Adam Eaton.

Quintana, who turns 28 in January, is due $15.85 million over the next two seasons with club options for 2019 ($10.5 million) and '20 ($11.5 million).
