Koo: Oakland’s other platoon advantage

From Andrew Koo at Baseball Prospectus on December 18, 2013:

The Oakland Athletics finished 2013 with baseball’s fourth-lowest payroll, fourth-best offense, and best clubhouse chemistry. Debate has centered on whether the latter two are related. There’s nothing objectionable about “good guy” genes—it’s a solid organizational goal to have. But chemistry alone doesn’t put runs on the board, and if a team is missing the talent, they better find the runs elsewhere. The 2002 Athletics discovered them in walk deities and college arms; once those methods pervaded front offices, the A’s slipped back into losing. Was chemistry the only undervalued commodity of their recent resurgence?

As the baseball community obtains more knowledge, roster construction strategies evolve. Previously undervalued talents like walks and defense are now accepted constructs. The A’s are Hollywood-infamous for adopting them before their competitors while prices were low. After a 74-win 2011, they cheaply signed Brandon Inge and Jonny Gomes, who Brandon McCarthy claimed bolstered the clubhouse DNA to the tune of 20 wins. But Inge and Gomes were two of several players who also bolstered a less-visible statistic: fly ball-to-ground ball ratio.


Since 2009, fly ball rates (which exclude popups here) have gradually decreased. Oakland has defied this trend, ranking first from 2012-13. What caused the A’s jump? Let’s inspect their transaction logs, beginning with their acquisitions for 2012.
