The Royals and Giants are working on the details to send the OF to the Bay area.
The deal was expected to be completed in time for Guillen to fly to San Francisco in time for the series against the Padres that starts Friday night.
Guillen was hitting .255 with 16 homers and 62 RBIs this season for the Royals who designated him for assignment last week. The team has until Saturday to trade, release, or reinstate Guillen.
