Think you know the ins and outs of baseball better than your favorite team's manager? If you're a Reds fan, you might actually be right! But the guys at USS Mariner have created a new iPhone app that will help you amateur sabermetricians accomplish the impossible: being twice as annoying when you second guess your favorite team's decisions at the ballpark. It uses live win expectancy and the run expectation of the current situation to tell you just how dumb Jim Tracy was for calling that double steal.
Be sure to check the App Store for future updates that let you second guess player trades and rate the odor of your own farts.
