Randy Johnson Diamondbacks pitcher,45, was reacquired from the Yankees in January 2007. He is in his final year of a 2-year, $26 million dollar contract extension that was agreed upon in his deal. Johnson missed most of last season with a back injury. He was slow to return to form this season.  Many people believe that the Diamondbacks pitcher was in the twilight of his Hall-of-Fame career and…now pitching like the old days.

Since the All-Star break, Randy Johnson is 4-1 with an astounding 1.08 ERA in five starts. What’s happening?
