When Catfish Hunter beat the Oakland A’s, 6-2, on August 27, 1978, he completed a six-win/no-loss August that helped propel the Yankees on their way in their momentous climb from 14 games back of the Red Sox.
Double/single, then a walk and back-to-back errors, then double/single again gave the Bombers a 6-1 first-inning lead over the Mariners in Yankee Stadium on August 27, 2017, in an eventual 10-1 win. A brilliant Masahiro Tanaka struck out 10 over seven, and the surprising big hit on back-to-back days was delivered by Jacoby Ellsbury.
