The club also needs minor league talent to attract a proven big league run-producer in trade.
Todd Wellemeyer's pitching well for the Fresno Grizzlies in the Pacific Coast League, but that doesn't mean that fans calling for the club to trade Jonathan Sanchez for a hitter have any idea how difficult it would be to fill the No. 4 spot in the rotation.
Oh, there are starting pitchers in Triple-A—but there's a good reason that only one has ever reached the big league level and for the big club's hesitance to turn a starting spot back over to Wellemeyer.
The organization does have some talent other teams might seek in trade, but the most proven player in Fresno is middle infielder Emmanuel Burriss and the Giants could use him themselves down the stretch.
