Starting pitching has provided some unlikely fantasy assets these season, but who should you bank on down the stretch? After 100 games in the 2008 season, the top three ERA leaders are Justin Duchscherer, Cliff Lee, and Edinson Volquez. There have certainly been surprises with hitters as well, but not to this extent. The day that baseball becomes predictable will also be the time it becomes boring, but 2008 has brought an especially erratic season for starting pitchers.

Getting a better read on a player's hitting profile to determine his true level. In midAugust I was reading an article on a friend's blog, in which he was reflecting on his preseason MLB award predictions and lamenting his pick of Chris B. Young for NL Rookie of the Year. Since I had hyped Young to him prior to the season, I felt it necessary to reply and defend my prognostication. Young was hitting just .235 at the time, but had 25 or so home runs, and had already built a reputation as a premier baserunner. In defense of my pick, I hastily replied, "He's had bad luck. If you gave him even a leagueaverage batting average on balls in play, he'd be hitting .270 and have AllStar overall numbers." Something about my statement, however, did not seem intuitively correct. I knew that multiplying a player's balls in play total by a leagueaverage BABIP and adding in the home runs was, at best, a brute force measure of what the player "should" be hitting, only slightly less variable than a player's batting average itself. Still, I thought that with Young's combination of power and speed, he should ideally be hitting with at least average luck on balls in play.

Its more likely that hes a .290 hitter who had a few balls bounce his way, and the Baseline attempts to correct for this. \nSimilarly, a pitcher with an unusually low EqHR9 rate, but a high flyball rate, is likely to have achieved the low EqHR9 partly as a result of luck. In addition, the Baseline corrects for large disparities between a pitchers ERA and his PERA, and an unusually high or low hit rate on balls in play, which are highly subject to luck.

The Tigers take on a completely different personality at the plate, and use it to win. \nMathematically, leverage is based on the win expectancy work done by Keith Woolner in BP 2005, and is defined as the change in the probability of winning the game from scoring (or allowing) one additional run in the current game situation divided by the change in probability from scoring\n(or allowing) one run at the start of the game.'; xxxpxxxxx1160590386_18 = 'Adjusted Pitcher Wins.
