I know Arrieta has a longer track record than Medlen does but I keep thinking about the Braves-Cards game in 2012. He made 12 starts for Atlanta that year, all after July 31. They were 12-0 in those games and he had a 0.97 ERA over 83 2/3 innings. He'd given up 11 runs in those 12 starts but gave up 5 (only 2 earned) against St. Louis. Well, it's a good thing we have Jake Arrieta on our team rather than Kris Medlen.
