There are 54 separate Defensive Misplays and 28 separate Good Fielding Plays that Baseball Info Solutions has “scouted” going back to 2004.  One of our biggest undertakings in the last three years has been to convert Good Fielding Plays and Defensive Misplays into Runs Saved.  Today we’re going to walk through an example that shows the magnitude of what we now refer to as Good Play/Misplay Runs Saved.

Take, for example, Alfonso Soriano of the Chicago Cubs.  He’s now 36 years old and a below-average outfielder, according to Good Plays and Misplays.  In fact, his 13 runs lost on Good Plays and Misplays in the last three years is the worst among all outfielders. He had 22 Good Plays, 73 Misplays and 25 Errors. That’s 76 more misplays and errors than good plays. The next worst left fielder is exactly half as bad. Logan Morrison had 38 more misplays and errors than good plays. The best left fielder in GPF/DME runs saved is Jason Bay. He had 73 good plays and only 47 misplays and errors in the three years, a net of 26. Compared to Soriano’s net of -76. Here is how they compare in runs saved:

Soriano has cost his team 13 runs with his poor play in the field since 2009 on Good Plays and Misplays alone, while Bay has saved his team 7 runs in that time.  That’s a difference of 20 runs, or roughly two wins.  That’s huge.

What we can see from the chart is that Soriano struggles in a number of areas.  In fact, the only areas where he rates as average or better are “Wasted throw after hit/error” and “Cutting off runner at home.”   In these types of plays, Soriano performs at least how we’d expect an average fielder to perform, in the same opportunities as Soriano.  In every other way, Soriano rates below-average.  The biggest problem Soriano has, according to Good Plays and Misplays, is “Mishandling the ball after a safe hit”, where he cost his team four runs since 2009.  Jason Bay, on the other hand, excelled in that department, saving his ream three runs by having far fewer Misplays for “Mishandling the ball after a safe hit” than an average fielder would have in the same number of opportunities as Bay.  Bay is also slightly above-average in three other categories: “Outfield assist after hit or error”, “Holds to single” and “Wasted throw after hit/error.”
