I didn't see this posted in the archives anywhere, so figured I'd highlight an awesome article from last October.
Last year, Romo, backed the league into a corner and slapped it around like E. Honda in Super Street Fighter Turbo 2:
In addition to a ludicrous 25 FIP- (which neutralizes for context), he had the third-best FIP in history and the lowest SIERA (which captures his peripherals more effectively than xFIP) in the stat’s young history (which only goes back to 2002).
What’s especially flabbergasting, though, is how other signs of regression appear to be rather neutral. For instance, his BABIP was above his career norm and his HR/FB ratio was less than a percent lower than his usual rate. His LOB% (83.3%) was actually down from the previous year (86.3%), though it still seemed a touch high (his career rate is 76.6%, but he seemed to either settle in the 60s or 80s).
