I wrote about Cliff Lee and Orel Hershiser over on SB Nation Los Angeles. Hershiser finished his 1988 with a 10-1 record in 14 starts with an ERA of 0.65. He averaged 8.89 innings per start:
In those 14 starts, ranging from August 19 to October 20, Hershiser pitched 11 complete games, plus another game in which he threw 10 scoreless innings in a no-decision.
That's a heck of a two-month stretch.
