According to Bruce Levine on ESPN 1000, there are two theories on the Z explosion... 1) Z was upset with Lee's effort on the ground ball down the first base line. 2) Z was upset because he thought the ground ball down the line was foul and nobody else would back him up. Jurko and Harry are backing Z up, questioning Lee's effort, with Jurko saying that Z is just an "emotional player on an emotionless team" and should have gone back out for the 2nd inning. That just reinforces why I have never liked Jurko.
