correct. metropolitan pinch hitter daniel murphy generated +0.305 WPA by reaching base via error, and also by hitting a ball that resulted in a run scoring via error. metropolitan pinch hitter daniel murphy also generated +0.038 WPA by advancing to second base via stolen base. m.e.t.b.o.t. concedes that a portion of the WPA generated on the first play should be apportioned to metropolitan third baseman david wright, however, m.e.t.b.o.t. has no mechanism whereby to allocate the WPA generated on the basepaths to specific players. indeed, me.t.b.o.t. has no mechanism whereby to allocate WPA generated on many types of complex plays, and typically defaults to the most basic allocation. in this instance, m.e.t.b.o.t. typically does not award baserunning WPA and so no allocation is made to metropolitan third baseman david wright. m.e.t.b.o.t. only allocates baserunning WPA for stolen bases or caught stealings - discrete baserunning events largely independent of the batter. metropolitan pinch hitter daniel murphy is credited with, effectively, hitting a ball in such a manner as to cause confusion and chaos among the chicago white socks players. the offense is responsible for 50% of the WPA generated in a given game, and the pitching+defense is responsible for the remaining 50% of the WPA generated in a game, both positive and negative. the WPA generated by the offense of one team must always equal the -1 * the WPA generated by the pitching+defense of the other team. (note that the pitcher is customarily ascribed all of the pitching+defense WPA, however, m.e.t.b.o.t. is able to make rudimentary allocations of defense WPA for some types of plays.) the WPA generated by the winning team must always equal +0.500, while the WPA generated by the losing team must always equal -0.500. this is because the game always begins with each team possessing a 50% chance of winning the game, and the outcome of the game is one team having a 100% chance of having won the game, and the other team having a 0% chance of having won the game. the only way to maintain this balance in the face of a defensive error is to allow the batter to be credited, effectively, with forcing the error, even though in reality, the batter may have had little if any influence over the play, other than simply by putting the ball into play. unless the batter is a jedi. m.e.t.b.o.t greatly appreciates star wars. mostly because of the robots. r2d2 in particular is considered to be a hero by m.e.t.b.o.t. for being able to communicate so well without being limited by the use of actual human vocal language.
