I agree with Briggs. Sanchez is probably the better value to us. To get Greinke, we would have to trade Hardy most likely. Since there's no replacement on the free agent market, and I don't trust that Escobar is ready, I wouldn't do that trade. It strengthens the rotation, but severely weakens the offense. The same can't be said about a Hart for Sanchez swap. There are still plenty of outfielders on the market that could replace and probably do better than Hart. Sanchez posted a 3.85 FIP and tRA of 4.23 last year and struck out a batter per inning. He also had a high BABIP and low LOB%. If those get to around league average, he'll improve. He also seemed to hit a wall, at the end of June he had a 3.79 ERA in 102 innings. Problem is he only pitched 63.2 innings the year before, so there may have been some fatigue. I'm just not sure the Giants would trade Sanchez for Hart. They have Lewis, Sanchez, Winn and Schierholtz in the minors. Outfielder doesn't seem to be a pressing need for them.
