Update of MLB's runs scored, runs allowed, run differential and luck. Luck is a tool from Baseball-Reference that provides the difference between a team's actual record and Pythagorean W-L. For example, the Cardinals are second in the NL in run differential yet only one game over .500 and in third place in the Central. Based on their run differential, they should be 37-26 not 32-31. Baltimore is 10 games over .500 yet a modest +4 in run differential. Pittsburgh is three games over .500 but has been outscored by 25 runs.
