On-Base Percentage, And Where The A's Rank In It

As is commonly known, Billy Beane's Monyeball theory had a particular focus on On-base percentage. On-base percentage, or OBP for short, measures how often a hitter gets on base. Unlike batting average, it measures not only hits but walks, and hit by pitches. Then, those three statistics are divided by at-bats, walks, hit by pitches, and sacrifice flies, or, simply, plate appearances. Moneyball was very fond of this stat; after all, how else did Jeremy Giambi find himself batting leadoff? So, let's see how the A's are doing.

First, a look at the team stats:

Boston is first, with a team OBP of .353. Unsurprising, considering Boston's potent offense. The Yankees are second, at .342. Then come the Cardinals, at .340, the Mets, at .335, and the Rangers, at .334. The A's rank very low, at just .308. They're 24th. The Mariners are last (gasp!) with a meagre .289 team OBP. Oakland is 13 points below the league average, and 11 points below the MLB average. No better here than in any other offensive category.

Now, the stats of each A's player:

Eric Sogard leads the team, with an OBP of .357. Go geeks!

Ryan Sweeney is second, at .348, then Jemile Weeks, at .341. Coincidentally, none of these three players have been starters all year long. 

The first starter on the list is Willingham, with an OBP of .327. He's followed by Conor Jackson, Daric Barton, and Coco Crisp. The player with the lowest OBP (not counting pitchers) is Chris Carter. Second to last: Adam Rosales.

The OBP's of the big offseason pickups - Willingham, DeJesus, Matsui - are all way down, 40-50 points below their career OBP's and season averages.
