I've done a lot of tweeting about streak-related developments over the past few months (see link to my Twitter feed in the right-hand column), rather than writing deeper analyses. However, I've now conducted a detailed analysis of the L.A. Dodgers' 42-8 spurt midway through the 2013 season (one of best 50-game stretches in MLB history).
