Paul McAnulty was recalled from Triple-A Portland to provide outfield support.
Giles, 36, has not played since May 19 because of a bone bruise in his right knee. He hasn't felt any better with rest.
"For a while, it was only when I was decelerating that it would bother me a bit," Giles said. "But it got to the point that it was getting a bit cranky when I was accelerating. Hopefully, it will calm down."
The Padres offered no timetable for Giles' return, although he said he hopes to be able to play June 5, when the Padres open their next homestand against the Los Angeles Dodgers.
The DL move was made retroactive to May 20. Giles has a .276 batting average, one home run and 12 RBIs in 42 games. Giles believes he was hurt in mid-April when he banged the knee against the hard wall at Wrigley Field. The injury got progressively worse and took his statistics down.
Giles was batting .318 on April 24 but is only 20-for-85 (.235) since. McAnulty, 26, opened the season with the Padres and was 1-for-8 before he was optioned to Portland. The left-handed batter hit .277 with two home runs and 15 RBIs in 32 games with the Beavers.
Hoffman OK: Padres closer Trevor Hoffman pronounced himself fit and ready after playing long toss during batting practice. He ceded the ninth inning to Scott Linebrink on Friday because of discomfort in his right shoulder.
"I hate to see too much made of it," Hoffman said. "It's one of those situations where my arm was a little cranky and another day of rest would have benefited. Discretion was the better part of valor."
Linebrink, meanwhile, said it happens "about five" times a year that he gets word he is on standby to close because Hoffman needs rest.
"Usually, nobody knows about it because that [save] situation doesn't come up," Linebrink said.
This time, most everyone outside the home dugout and bullpen was surprised when Linebrink jogged in for the ninth Friday to the tune of Metallica's "Enter Sandman." Some fans booed when they were denied Hoffman's usual entrance to "Hells Bells."
"Tough crowd," Linebrink said with a laugh. "I guess we had a few hardcore AC/DC fans out there."
Kouzmanoff on rise: Third baseman Kevin Kouzmanoff batted fifth Saturday against the Milwaukee Brewers, his highest spot in the lineup this season. He entered the game riding an eight-game hitting streak, in which he hit .520 (13-for-25) with three home runs and 12 RBIs.
"It doesn't really make a difference," Kouzmanoff said of his ascension in the lineup. "Not to me anyway. You're still trying to get hits, still trying to drive in runs."
Manager Bud Black said he plans to keep Kouzmanoff in the No. 5 spot for home games. That's a hint shortstop Khalil Greene will bat fifth on the road. Greene entered Saturday batting .161 with three home runs in 24 games at PETCO Park and .275 with three homers in 22 road games.
Greene rests: Greene's home struggles convinced Black to give him a day off Saturday, so Geoff Blum started at shortstop. Blum might be in there again Sunday so that Greene gets a three-day breather. The Padres are off Monday before beginning a road trip in Pittsburgh.
Greene was 0-for-15 on the homestand entering Saturday.
"Days off sometimes benefit players and sometimes don't," Black said. "Most times, when a player isn't swinging like he's capable of, it's more beneficial."
Up next: The Padres close out the three-game series against the Brewers at 1:05 p.m. PT on Sunday. Jake Peavy (6-1, 1.63 ERA) takes the mound for San Diego, opposed by Jeff Suppan (6-4, 3.49).
