OAKLAND - In a development few could have predicted, perhaps not even general manager Billy Beane, the A's infield has evolved into the backbone of the 2013 team.
It has outperformed what was a highly touted outfield group, and might even surpass the pitching rotation and bullpen, all things considered.
It seems like an eon ago now, but when spring training began, the A's infield situation wasn't just one big question mark, it was four. There was a measure of doubt at every position.
The double-play combination was supposed to be Scott Sizemore at second base and Japanese import Hiroyuki Nakajima at shortstop. Nakajima had never played a day in the majors and Sizemore had missed the 2012 season because of knee surgery.
There also was uneasiness about the corner infielders. Josh Donaldson had showed promise at third base, but his 2012 totals were nine homers and a .241 batting average in 75 games. Over at first, Brandon Moss hit .291 with 21 homers in 84 games, but there was uncertainty whether he could duplicate those numbers based on his journeyman resume.
When the A's couldn't re-sign Stephen Drew, who took over at shortstop for the final month and a half of 2012, questions arose about why Beane traded experienced, reliable shortstop Cliff Pennington to the Arizona Diamondbacks.
Eight months later, it all seems like so much wasted worry.
It's easy to point to the acquisition of Jed Lowrie from Houston on Feb. 4 for first baseman Chris Carter and pitcher Brad Peacock as the turning point, but at the time it appeared manager Bob Melvin just had more uncertainties to consider.
“We weren't really sure in spring training what position Lowrie was going to play,” Melvin said. “It looked like Sizemore was going to be our everyday second baseman. We didn't know Eric Sogard was going to come on like he did. So we knew we might be flipping some pieces around as the season went along.”
