"To be honest, I don't really pay attention to the lineup," said Harrison, who led off Thursday with a homer. "The lineup gets jumbled so much and we don't pay attention too much to what could be the Opening Day lineup and what could not. ... That's more [the media's] job, to look at the lineup and say maybe Opening Day, but none of us here have said, 'This may be our Opening Day lineup.'
"At the end of the day, we've got to worry about the task at hand and that's getting better every day."
McCutchen is essentially guaranteed to bat third for Pittsburgh. He did so in all 146 games he played last season.
Marte has seen a lot of time in the five hole this spring, perhaps an indication of where he'll spend most of his days this season. Marte started at least 17 games at five different spots in the order last year, including 29 games each batting first and fifth.
Harrison started 83 games in the leadoff spot last year, and it appears he'll start this year there again. He hit .328/.359/.535 atop the order in 2014, so the spot seems to agree with him.
"Your approach changes at-bat to at-bat," Harrison said. "My leadoff approach changes day to day as well. They attacked me differently throughout the course of last year. The last month and a half, guys started mixing it up on me early. My approach is to go out there and get a good pitch to hit -- so in the grand scheme of things, my approach really doesn't change."
