SAN DIEGO -- Maybe a stint on the disabled list will be the tonic for what ails Homer Bailey.
The Reds put the right-hander on the 10-day DL with right knee inflammation, retroactive to Wednesday, before Saturday's game against the Padres. Austin Brice, another righty, was activated off the DL.
Interim manager Jim Riggleman said Bailey, who was sent to the bullpen earlier this week, was diagnosed in San Diego on Friday.
"This is what they came up with," Riggleman said. "There are some issues there, but we don't think it is anything major. He'll take a few days off and not throw, not test it out, and we'll just kind of go from there when we get back in [Cincinnati] next week."
Bailey (1-7) was removed from the rotation after scuffling against the D-backs on Monday. His 6.68 ERA over 12 starts is the worst in the National League among qualified pitchers.
"Homer has dealt with a knee issue for about a month that has not stopped him from pitching," Riggleman said. "But it also has maybe not allowed him to be at his best. I think it's a really good idea to take a break from it and let it really calm down -- see if it helps him."
Brice (back) last threw to live hitters at the team's Arizona facility on Wednesday and was available out of the bullpen Saturday.
Fast healer
Speedy center fielder Billy Hamilton didn't take a day off after crashing into the wall on Friday night. Hamilton was running full speed in pursuit of Freddy Galvis' triple in the ninth inning when he made hard contact with the padded fence.

"We didn't put the lineup up for a while because he took a pretty good hit last night and we wanted to see how he did in the trainer's room,'' Riggleman said. "But he insisted. He is sore, but is ready to go."
Hamilton's left side absorbed most of the blow, with his collarbone taking the worst of it. When Riggleman reached Hamilton after the play, he wasn't sure how badly he was hurt.
"I couldn't tell if it was his cheek, his neck, whatever," Riggleman said. "He wasn't saying a whole lot."
A month to remember
Scooter Gennett's sizzling May was accented by being named the National League Player of the Month for May. Gennett, who entered Saturday's game leading the NL with a .341 average, batted .398 over the month.
Gennett's newfound muscle produced eight homers and 24 RBIs last month. The second baseman homered in four straight games from May 7-11 in leading the Reds to a sweep over the Dodgers.
"It's a honor, man, because there was a lot of guys that did well,'' Gennett said. "But it's aways nice to be recognized and to know that there are some people watching us out there."
Gennett has the luxury of knowing his name is penciled in the lineup on a daily basis.
"It's being able to play every day and know if I have an O-fer we'll go get 'em tomorrow," he said. "If you're in a platoon role, or a rotational role, it's that 'I need to do well so I can play tomorrow.' That's a tough way to play the game. It's very hard. Being in there every day definitely makes it a lot easier."
