What changes do you think need to be made?

First off, a game won in April is one less game needed to be won in September, especially against our division rival. We have played two legit contenders and have lost both series. In the Braves series so far, Detwiler had 7 IP with only 1 earned run. Strasburg took the loss with 0 ER. Those things should not happen. The bullpen and defense behind our brilliant starters is lacking right now. What would you do if you were Rizzo/Davey?
