So let's retrace the fatman's steps. He makes his ABs clause in his contract then refused to pinch hit, affectively ending his season. Was he already drinking or drugging heavily?
Fast forward and he doesn't make it to pre-season tours because he is working with a personal trainer to get into shape. He then comes to camp in such great shape that he gets injured immediately. Maybe he was trying to dry out instead of work out?
Somehow he manages to put down the bottle long enough to swing and miss a handful of pitches before his renewed, trimmed down body breaks down and he disappears. He does however manage to spend some quality time with his girlfriend, now known simply as the defendant, or victim.
At least we can now take his picture off of all the milk cartons, he's been found. Or found out.
