An interesting matchup in the Yankees-Twins game. Defensive Efficiency measures the ability of a defense to turn a ball in play (other than HRs) into an out. The Twins lead the majors with a mark of .757 (or, 76% of balls put into play against them are turned into outs). The Yankees have the worst DER at .647. That means that for every 100 balls put into play against these two clubs, the Twins will get 11 more outs. That's almost four innings worth of outs. The Yankee pitchers make up for this somewhat by walking few batters and allowing few HR. But the Twins have a 3.22 ERA, and the Yankees a 3.35 ERA.

Of course, after this discourse, Soriano leads off with a HR!
