FanGraphs | Sheryl Ring: Arbitration needs to be fixed, plain and simple. While free agents get paid less the actual young players are getting the same treatment, except through strategies like: better and more expensive lawyers; information asymmetry; and, the strategy of “file-and-trial.”

Baseball Prospectus | Aaron Gleeman ($): We’re back to the Manny Machado and Bryce Harper projection well, and now PECOTA is at it, forecasting their WARP production, and I won’t spoil it, but shocker: they would be worth a big deal!

Bill James Online | Bill James: The issue with the unearned run is that pitchers are technically responsible for those balls put in play that become errors, but RA9 assumes that the responsibility for them is all equal, which we know isn’t true, either. But if we were to assign some responsibility to unearned runs, even if it’s 50%, it would be closer to the answer than either of those two theories.
