"The new Moneyball: How the A's built a surprise contender"
"As has been noted many times before, Moneyball wasn't about the particular skill of on-base percentage so much as it was about exploiting market inefficiencies that undervalued some players.
With this thought in mind, SI.com has tried to reverse-engineer Oakland's success this season in an effort to shed light on where the Billy Beane-led front office has found value.
Platoon advantages
"As a result, the A's have had 3,840 plate appearances in which a righthanded batter faced a lefthanded pitcher or a lefty batter opposed a righty on the mound; that's the second-largest total of opposite-handed plate appearances in the majors behind only the Giants and accounts for 65 percent of Oakland's total PAs.
Oakland has benefited from these favorable matchups. Among lefthanded bats, Brandon Moss has 17 home runs and a .958 OPS in his 215 PAs against righthanders, Seth Smith has 12 home runs and an .823 OPS in his 349 PAs and George Kottaras -- who hit a game-winning homer Tuesday night -- has six HRs and an .803 OPS in 65 PAs. Conversely, Jonny Gomes has 10 HRs and a .938 OPS in 184 PAs against southpaws, Chris Carter has five HRs and a .921 OPS in his 103 PAs and Collin Cowgill has one homer and an .844 OPS in 51 PAs.
So while players would prefer to play every day, the A's have bought in, almost universally repeating a certain buzz-phrase.
"It's something most of us haven't done," Carter said, "but I think it's putting hitters in a position to succeed."
"Every team would love to have a set nine," shortstop-turned-second baseman Cliff Pennington said. "That's kind of the goal, but we've got a good thing going here playing matchups. Bob Melvin puts us in a position to succeed, and that's been working for us." "

"The all-platoon team"
"When it comes down to it, there are just more starting positions in the major leagues than there are players worthy of getting that many at-bats, and while no team has ever gone to the extreme I’m about to, the point remains that sometimes two flawed players, when their flaws complement each other properly, can come together to produce at an all-star level"
Alderson is the initiator of "Moneyball" in MLB. Taught Beane (who was Alderson's Assistant GM in Oakland) the concepts of "Moneyball." Think Alderson's looking at platoons as a way to go in 2013.
Gil Hodges also used platoons to great effect in 1969. Had FOUR regular platoons. Other great managers of the past used them too. Casey Stengel was another famous one. Davey Johnson had Lenny & Mookie platoon too. Think platoons are a very good idea that's been proven successful.
