Perez lasted just 4.2 innings Sunday, allowing three four runs on three hits and three walks with four strikeouts.
Fortunately for him, Adam Wainwright was having just as much trouble finding the strike zone as Perez was. The Braves don't have many other options for their rotation at the moment, but Perez will need to pitch better than this if he wants to stick around. His next chance to try and firm up his spot will come Friday in Miami.
