I greatly enjoyed watching Danny Duffy & James Shields have back-to-back great starts in a split doubleheader in Detroit earlier this month, and it made me wonder about other double whammy starts in team history. I used a game score of 65 as the arbitrary cut-off for an excellent start, and found the below 12 instances when both Royals starters reached that mark in a doubleheader. Duffy (70) and Shields (68) combined for the sixth best average game score out of the 12 twin bills in question.
Over the first eight Royals seasons (1969-77), there were nine doubleheaders in which both KC starters were good enough for a 65+ game score. Then as doubleheaders became a rarity, so of course did doubleheaders with two excellent starts. It didn't happen again until 1990 when Kevin Appier and Luis Aquino turned the trick, then not again until 2001 with the legendary duo of Jeff Suppan and Chris George. That was the last time until Duffy & Shields, Inc. this season.
