A lot of people think the Giants should go after a big bat at the trade deadline. However, they don't need to.
As I mentioned in the last slide, the Giants have received some clutch, timely hitting that has allowed them to win games. They have Cabrera and Posey dominating, and even though Pablo Sandoval and Angel Pagan have been struggling, the Giants still have been great on offense recently.
Brandon Crawford and Brandon Belt have lots of potential, even though both have been very streaky. Crawford's huge three-run blast was just one of the great things he's done with runners on base, and when Belt's seeing the ball well, he isn't fun to pitch too.
All the Giants really need is a closer. Santiago Casilla blew his sixth save of the year when he allowed Brian McCann's two-run home run with two outs in the 10th, and it was his fifth blown save in his last eight chances. In his last eight appearances, Casilla's ERA has shot upwards from 1.32 to 3.34.
Even though the Giants have Javier Lopez, Sergio Romo, George Kontos, Brad Penny, Clay Hensley and Jeremy Affeldt in the bullpen, they would benefit from getting a closer.
San Francisco is looking to upgrade in the bullpen, but they could also pursue a middle infielder like Michael Cuddyer (even though they don't need any bats).
However, every position other than pitcher is filled by capable players.
I already mentioned most of the position players, and the ones I didn't mention, Ryan Theriot (second base) and Gregor Blanco (right field), have done a nice job. The Giants are fine at all positions and don't need to give up valuable prospects for a position player.
And that's because everyone who takes the field for the Giants is capable of succeeding.
