Oddly enough, there actually is a baseball statistic that takes strikeouts out of the equation. It also takes out home runs. It's called Batting Average on Balls In Play or BABIP. You can see the formula here:
http://en.wikipedia.org/wiki/Batting_average_on_balls_in_pla...BABIP doesn't tell you a ton about a player's overall performance, but it does tell you how lucky they've been if you compare it to their historical BABIP. Some guys have awful years because their skills fall off a cliff (Adam Dunn is in that camp right now). But some player just have terribly unlucky seasons in terms of how defense affects the balls they put in play.
If a player's BABIP is way down (or up), but his line drive rate, strikeout percentage, and home run rates are the same, you can make a good guess that his batting average will regress back towards his historical average.
I'm sure if you told the average baseball fan about BABIP, he or she would call it BS. Yet, it's a great metric for determining whether a player's poor/excellent performance is sustainable.
