But now this year, he has a whopping 0.59 ERA?!?!?!?!?!? Yes I know its beginning of season but still, this brings me to question: DO pitchers have slumps? And do Pitchers have a stud year?

From An Introduction to Sabermetrics Streakiness? Another interesting question is on the existence of streakiness in hitting data. During a season it is observed that some ballplayers will experience periods of ``hot" hitting where they will get a high proportion of hits. Other hitters will go through slumps or periods of hitting with very few hits. But these periods of hot and cold hitting may be just a reflection of the natural variability observed in coin tossing. Is there statistical evidence for a ``hot hand" among baseball hitters where the probability of obtain a hit is dependent on recent at-bats? Albright (1993) looked at a large collection of baseball hitting data and used a number of statistics such as the number of runs to detect streakiness in hitting data. His main conclusion was that there little statistical evidence generally for a hot hand in baseball hitting.
