Call-up profile: Jarrod Parker, SP

The situation: With right-handed starter Graham Godfrey struggling to miss bats in the big leagues, the A's reached down to their suddenly deep minor league system to grab Jarrod Parker, the top prospect received from the Arizona Diamondbacks for Trevor Cahill. Parker will make his Oakland debut Wednesday.

Background: Parker was the ninth overall pick in the 2007 draft, but there were pre-draft rumors that he could have gone as high as No. 3 overall to the Cubs. He was the first high school pitcher selected that June.
