The situations don't matter because you are looking at this stuff in vacuum. They have run studies on how accurately OBP, AVG, SLG, OPS can predict runs. OPS does a very good job, weighted OPS that gives more value to OBP than SLG does an even better job. Never seen one that suggests AVG is more useful than anything else, in fact AVG has less predictive value than OBP or SLG by themselves much less the two combined. Here is an example of some of the Math behind it, found this with a quick google search, I'm sure there is more in depth stuff out there but it all ends up with the same conclusions in every study I've ever seen. http://bluethinktank.blog...2005/12/power-of-ops.html Here is an article including the value of each given result in 2007. http://spiff.rit.edu/rich...ball/lwts/lwts_intro.html Rickie Weeks that year had a .235/.374/.433/.807 and was worth 13.2 LWTS/603 (this includes some value for his 25 SB and losing value for different types of outs etc). He was the 3rd most productive offensive 2B in the NL that season behind Utley and Kent even though he hit .235.
