Derek is sure this will be the best season yet! He has it all planned-his dad will have him start at shortstop, and the team will cruise to a championship. But sometimes life doesnt go according to plan.

Season four returns a few months after the bombshell revelation that Dr. Jason Bull is expecting a child with his ex-wife and Benny's sister, Isabella Coln̤. While Bull prepares for impending fatherhood at home, his work at TAC suffers in the wake of Benny's resignation as TAC's staff attorney after learning Bull slept with Isabel at their father's funeral.
