Sveum Fired Up With 1-7 Jackson

Before the Chicago cubs loss to the Pittsburgh pirates Thursday Sveum seemed frustrated with some of his line up issues. After the game it seemed he took his frustration out on the $52 million acquisition  Edwin Jackson. A poor start in his first year of four thus far for Jackson.
"Obviously not real sharp," Sveum said. "No fastball command. Didn't come out with any velocity at the beginning." 
"It's a game of adjustments," Jackson said. "It's a matter of making better adjustments before you get hurt."

So for now, the Cubs will keep sending him out there trying to find some answers as any step forward by Jackson has been followed by at least one step back. Why he can't find that consistency is frustrating his manager.
