We define efficiency here as the dollar cost per win this season. 

$ per win =  total team salary/wins 

Of course, costs per win will decrease as the denominator increases as teams play more games and finish the season. 

So far, the Orioles are the most efficient, spending $1.2 million per win while having a winning percentage above .600 percent.  Conversely, the Mets are the most inefficient, spending almost $7 million per win, with the Yankee’s not far behind, shelling out $6.5 million per win. 

It’s also interesting that the trendline of dollars per win versus winning percentage is negative.  Money can’t buy me love, nor buy me baseball wins.   

Efficiency, as we define it, does not necessarily equate to winning World Series.  Nevertheless, we are enjoying a little schadenfreude, watching the Davids slay the Goliaths.  Sorry Mets fans.
