Aviles, who started at third base Friday, was not in the lineup Saturday.
"We definitely want Jose to play some, but Mikey always finds a way to get his at-bats, whether it's at short or third or left," Francona said. "That's never really been an issue. We'll do what we'll always do, play everyone and try to maximize our roster."
• Danny Salazar picked up his first win of 2014 Friday, and Francona said that the team is looking for continued growth from Salazar.
One key for Salazar, Francona said, would be a more aggressive approach. Rather than turning it on after he gets in a jam, Francona wants to see Salazar use his best stuff from the start.
"What we tried to talk to Danny about today, we didn't turn a couple of plays, but he also had a couple walks," Francona said. "Until he starts to get threatened, that's when you really see him start getting after it."
Salazar faced six leadoff batters Friday, and four of them reached base, including a pair of walks.
