One month later, the Rockies have gotten "hot" going 5-23 over their next 28 games, for a 9-48 record and a -177 run differential. For those wondering, the worst run differential since 1900 was turned in by the 1932 Red Sox at -349. So Colorado's over halfway to making history after only playing 57 games. The worst modern era record is still very much in play, too.
