For the final game of a three-game series against the Dodgers, the Padres' starting lineup had Luis Durango starting in center field, Matt Stairs in left field and Everth Cabrera at second base.
Regulars Ryan Ludwick (right field) and Chris Denorfia (center field) got rare starts off as did second baseman David Eckstein.
"The use of the roster is important," Black said. "It's one of the big reasons we are where we are. I think everybody has investment in this team, and I think it's great. It creates a situation where all these guys feel a part of what's going on, and all these guys are good baseball players.
"It gives [Dodgers starting pitcher Chad] Billingsley a little different look tonight as well."
Ludwick is hitting .173 with 20 strikeouts in 75 at-bats since Aug. 15.
"There are some guys on our roster that are going to help us moving forward, and you've got to try to keep these guys as current as possible," Black said. "This is an opportunity to do that tonight."
For Durango, recalled Tuesday from Triple-A Portland, it's his sixth start of the season in center field. For Stairs this is his ninth start of 2010 in left field. He's also started once in right field and once at first base.
The Dodgers followed suit, as regulars James Loney and Andre Ethier weren't in the starting lineup.
