From the Giants' official website's story on Garko's arrival:
Sabean suggested that another trade could be near fruition.
"We have one particular [Minor League] player who we're willing to trade that at least two teams are trying to make a decision on," he said.
Who could this next name be? Pucetas? Gillaspie? Take a shot... who's the next to go? Your guess is as good as mine, but I'm thinking it could be a corner infielder or another starter, as we now seem to have a slight surplus in those departments. And yes, i know, you can never have enough pitching, and TINSTAAPP, but i think with the Freak and Cainer in the bigs already and Madbum and Alderson on the way, we oughta be all right in the rotation for a bit of a while.
