Trumbo, who hasn't started at third base since Friday, was out of the lineup because of a viral infection -- with Scioscia coy about whether he would've started in the first place -- but may see plenty of time soon, with three lefties starting against the Angels in the next four days.
For Abreu, who came in batting .231, it was his first start at the leadoff spot since Aug. 28, 2010. The lefty-hitting slugger holds a .286 batting average and .391 on-base percentage while making 49 career starts as a table-setter.
He was there on Wednesday partly because of his on-base ability and partly to give Aybar (.171 batting average coming in) what Scioscia called "just a little recharge day."
"I think it's a good spot for Bobby," Scioscia said prior to the matchup with A's right-hander Bartolo Colon. "He's led off before, when he was younger, and the one thing about seeing pitches and getting on base is important out of anybody who's going to hit first or second. Right now, Howie [Kendrick] is getting comfortable hitting in the two-hole, and we'll give Bobby a chance to hopefully set the table ahead of him."
