Morris projects, to a neutral national league park, to be a .508 Owl, based on about 1000 at bats over his '97 and '98 minor league seasons. He is 33, and not likely to improve, while Morris is 25. In runs created terms, Morris creates 5.1 runs per nine innings, versus 3.2 for Benjamin. If those numbers are indeed accurate, and I have no reason to think they are not, then over 162 games, Morris's bat would give the Pirates 3.6 more wins than Benjamin's would. Now the fielding. .
Lets ignore double plays and errors for a moment.
Benjamin is a very good fielding second baseman, or so we believe. There are about 450 such fielding opportunities over 162 games for a 2nd baseman. Perhaps as a 2nd baseman, that number would average .985. Lets assume the difference in fielding average between Morris and Benjamin is .020. Pete Palmer concluded that a fielder who, by making a play that another fielder would not have made,has saved his team .75 runs.
