A quick glance at Greinke's stat line will give you the impression that he is having a very mediocre season. His ERA is sittting at 3.90, and his 3.99 FIP would show that this has been about what Zack deserves. If you are a die-hard traditionalist, the 6-5 record would support these metrics. It seems "meh," which is not what you would like from a guy being paid 31 Million bucks to throw a sphere past a guy with a stick. With Greinke pitching in his age-34 season, is this simply the natural decline of an aging ace? Age does play a role in Greinke's average results, but he is pitching far better than the surface stats would indicate.
