S4·E10 Hardball

Nash and Joe have to babysit Mickey Tripp (Paul Gleason), a motormouth shockjock, after a body armor-wearing assassin tries to kill him. Their search for the assassin is compounded by the fact that Nick has hired them on an off-duty case to find his softball team's star pitcher - a Salvadoran defector named Chus (Jose Canseco), who's on the run from the INS (Karl Malone). Caitlin babysits her roommate's kids.
