Here is the OPI (Offensive Production Index) for all AL players with at least 10 at bats.  It is early in the season so there are some very high numbers.  Last years leader was Frank Thomas at 0.682.  Teams are denoted by an * as the first character of the name and each player has his team preceeding his name.  The equations used are found at the end of the post.  Comments and suggestions are welcome.
