The A's lineup heading into spring training pivoted around one person -- first baseman Daric Barton.
If he made the team, the lineup would structure one way. If he didn't make the team, it would structure quite another.
Barton has had a nice spring offensively. Heading into Monday's game in Surprise against the Rangers, he carried a .298 batting average, but with no extra-base hits. He also had nine walks and had been hit by a pitch, leading to a .486 on-base percentage, which is something the A's value highly.
So heading into Monday's season opener, unless the A's pull off an unexpected switch, you can figure on Barton being at first base with last year's first baseman, Brandon Moss, serving as the DH. (Both men are likely to be on the bench when left-handed pitchers start).
If Barton hadn't made the team, the DH would have been catcher John Jaso, also left-handed, with Stephen Vogt and Derek Norris sharing the catching. There are those in the A's organization who see having three catchers as a possibility at some point later this season, but not now.
This level of success is a major about-face for Barton, who was repeatedly designated for assignment last year when it seemed his career in Oakland had been played out. But injuries in the outfield and behind the plate led to Moss moving to the outfield for a while and Jaso missing the last two months, and Barton thrived.
Called up for the final week of August, Barton hit .301 the rest of the way while posting a .381 on-base percentage. He's always been more of an on-base machine than a run producer, but over those 29 games he actually had more RBIs (13) than walks (12).
The knock on him in the past was that he was too passive at the plate, too willing to wait for walks and not going to the plate with the idea of driving in runs, but he showed new aggression last September. It's carried over to this year.
"I came here this spring to have fun, and I've done that,'' Barton said. "I'm more aggressive now. When they throw a strike, I'm swinging.''
