All the team had to give up is one minor league player -- Tim Alderson. Alderson is one of the Giants' hottest prospects.
That according to Sanchez's agent.
The Pirates were in San Francisco for a three game series with the Giants that started Monday, but Sanchez did not play due to a sore left knee.
Reports from the team’s website indicated that the Giants re-examined Sanchez's knee on Wednesday afternoon -- after having already performed an initial MRI on Monday, but wanted to take another look before agreeing to any deal.
