The winner, Trevor Cahill, pitched a great game against the weak offense of the Giants and only gave up one run in seven innings.
Sanchez is young and still has time to prove that he can be counted on but he has struggled too much this season. He needs to be sent to the bullpen to work on his off-speed pitches.
The Giants should bring up one of their pitchers from the minors to start in place of Sanchez and take over the fifth starter role.
Just like the Giants offense, Sanchez frustrates fans with his tendency to walk batters and give up hits at the most inopportune times.
Perhaps Madison Bumgarner or Tim Alderson could be called up by GM Brian Sabean sooner rather than later because Sanchez doesn't seem to have any confidence right now.
You knew it would be a bad night for him when he walked the first batter of the game on four pitches.
Aaron Rowand had a bad night as well and grounded into a double play as well as making a defensive gaffe in center field.
This season continues to make fans of the Giants frustrated and depressed. The offense is weak and boring, and there doesn't seem to be any help on the way.
The good news is that Tim Lincecum is pitching tonight, but the bad news is that he might not get any help from the Giants' batters.
