Jered Weaver of the Angels was suspended for 6 games for throwing at the head of Alex Avila of the Tigers right after Carlos Guillen homered and styled around the bases.
For a position player, a 6 game suspension means he misses 6 games.
For a starting pitcher, it means he has a start pushed back two games. Maybe at the end of the season it results in a missed start. Maybe not.
If Major League baseball wanted to help curtail the shenanigans of a pitcher intentionally throwing at a batters head, then they should make the suspension worth 6 starts, meaning a starting pitcher, like Weaver, should be suspended 30-games. As it stands now, he's missing games he wouldn't participate in anyway.
What about relief pitchers? How many games should they be suspended for in a similar situation? I haven't figured that out yet.
