Chapman, the left-hander whose fastball regularly exceeds 100 mph, has been linked to the Nationals, Cubs and Indians, as well as the Giants. But responsible industry sources doubt that San Francisco has engaged in any substantive talks with Yankees management about Chapman, whose domestic issues off the field have disturbed some potential suitors.
Since prospects continue to be baseball's most valuable form of currency, insiders say that the Giants continue to be asked for either or both of their most promising Minor Leaguers -- infielder Christian Arroyo and right-hander Tyler Beede, in various deals. The Giants are extremely reluctant to part with Arroyo or Beede. Mention of their names in negotiations tends to end any chance of a deal.
Relievers previously linked to the Giants in trade speculation include Milwaukee's Will Smith and Jeremy Jeffress, Philadelphia's Jeanmar Gomez and Andrew Bailey and Tampa Bay's Erasmo Ramirez.
