Sean Doolittle: Life as a player for the Oakland ‘Mathletics’

The 1940s Yankees had good wOPS…

Baseball is a game of numbers, and we at the Oakland Athletics keep track of everything… So exactly which metrics do the A’s value most when assessing potential players? I think I’ve finally figured it out…

wOPS (weighted overhead press): This gem calculates how strong a player is to determine whether he can carry a team. In Oakland, no one player carries our team. We all have very similar wOPS numbers.

BABIP: That’s batting average on balls in play, right? Wrong. It’s baseball averages compared to Bip Roberts. According to Baseball-Reference.com, over 12 seasons, Bip Roberts held a .294 batting average and a .358 on-base percentage and had a 162-game average of 36 stolen bases per year. Roberts played his final season for the A’s in 1998, but sabermetricians still use his stats when evaluating players…

Contact percentage: This metric is out of this world—literally. This number indicates how often a player is able to successfully decode messages received from outer space (just like Jodie Foster’s character in the 1997 film “Contact”). Although this is an interesting metric, it has nothing to do with baseball, so it’s not a great indicator of future performance. But it is a great movie…

Now if you’ll excuse me, I’m about to be shoved into my locker.

Neyer: The Jim Johnson Gambit fails

Gambit always fails.

Last winter, Matt Murphy noticed that a bunch of teams were signing veteran closers to good-sized contracts, even though the clubs already had impressive young closers-in-waiting. Was this merely fealty to Proven Closers run rampant? Or was something else going on?

Murphy focused on the A’s and found something else. Something really interesting. Murphy found that paying a veteran now means saving millions of dollars later, because your impressive young closers-in-waiting, if kept in setup roles for an extra season or two, won’t make as much money in the arbitration process. Because the arbitration is skewed, however ridiculously, toward saves.

Running the numbers, Murphy figured the A’s would save roughly $7 million on closer-in-waiting Ryan Cook’s salaries during his arbitration years, merely by keeping him out of the closer role in 2014. They’re paying [Jim] Johnson $10 million this season. But $10 million minus $7 million equals $3 million ... or Johnson’s effective cost in 2014…

I like the theory. But relief pitchers, leaving aside the elite, might just be too unstable for testing a theory that might cost you $10 million. Not to mention a few critical victories.
