With Jacob Degrom seemingly flirting with history this year (0.54 ERA through 11 starts), I was reminded of Orel Hershiser's scoreless innings streak in 1988.

Yup, that is a big fat zero earned runs given up over the entire month of September. With 5 shutouts in a row and it would have been 6 if the Dodgers had bothered to score a run in his last start.
I decided to check out Bob Gibson's game log in his famed 1968 year (1.12 ERA, Cy Young & MVP) and saw this:
Again, it was a different era of baseball, but damn. That's 19 (effectively) complete games in a row with 12 shutouts in the mix. His ERA fell below 1.00 twice during that span.
