Pence has just two hits in 21 at-bats this season, and he was kept out of the starting lineup for the first time of the season on Sunday against the Phillies.
The bigger move with the lineup may have been moving rookie shortstop Tommy Manzella to the No. 2 spot -- he hit eighth in three games and seventh in one -- for the first time, with second baseman Kazuo Matsui moving down in the order to seventh.
"We're gonna bat Tommy second and move Kaz down, just to see if we can get some things moving and take advantage of having Kaz, a left-handed hitter, down lower in the order," Mills said.
Manzella, who is hitting .286 (4-for-14) through his first four games, said that's the spot in the lineup he's primarily occupied during his time in the Minors.
"At this point, it's so early in the season and it's my first year -- I'm just doing whatever they tell me to do and try to execute it as best as I can," Manzella said. "The two-hole is a very comfortable position for me. That's pretty much the spot I've hit for the last seven years. It's not an unfamiliar spot for me. It's probably my most comfortable -- no, it's definitely my most comfortable spot in the lineup. When you get to this level, there are so many good levels that you have to adjust to whatever spot you're going to be in every day."
