KANSAS CITY -- James Shields' strained right lat muscle, which sent him to the disabled list for the first time in his career, is not responding the way he -- or the White Sox -- had hoped.
When Shields was placed on the 10-day DL retroactive to April 18, the plan was a quick return for the right-hander around the time he was scheduled to come off the disabled list. But that has been altered.
"We're going to kind of slow him down," manager Rick Renteria said. "He's been throwing every other day, and we're going to kind of shut that down a little bit and let that calm down. And then we'll proceed after that."
"It's kind of a slower process than I thought right now," Shields said. "It's not really responding the way I'd like it to be. We're just going to keep moving forward."

Shields feels good and was able to throw Tuesday.
"You'd wish it would respond a little bit better than what it is, but we've just got to take it day by day," Shields said. "I want to be out there as quickly as possible.
"My body feels good. The rest of my arm feels amazing right now. That's the good news. Getting some really good workouts in, and I'm going to cheer these guys on. We're going to continue to keep working right now, get this thing right."
Shields is 1-0 with a 1.62 ERA in three starts.
No news on Rodon
Renteria didn't provide much detail when asked Tuesday if left-hander Carlos Rodon has made any progress. Rodon is on the disabled list with biceps bursitis and is doing a throwing program in Arizona.
"He continues to be on his throwing program, and he's doing well," Renteria said. "He's progressing well."
When asked if Rodon was throwing off of a mound yet, Renteria smiled and provided the same answer. When asked if that answer was a no or Renteria simply couldn't say, he responded, "He's throwing and he's progressing well. And we're very happy with how he's moving along."
The Garcias are back together
Willy Garcia (LF), Leury Garcia (CF) and Avisail Garcia (RF) made up Tuesday's starting outfield for the White Sox, marking the second time in baseball history a team started all three outfielders with the same last name, per Elias. They played together on April 14 in Minnesota.
It was only a weekend appearance for Willy Garcia last time, filling in while Melky Cabrera was on paternity leave. He figures to be around a little longer now, taking the roster spot of Jacob May, who was optioned to Triple-A Charlotte following a loss to the Royals on Monday night.
"Now when I'm going to home plate, I'm going with a plan," said Willy Garcia through an interpreter of his .924 OPS at Charlotte. "I'm going with a focus just to swing at good pitches.
"Not to try to do too much. Just with a plan. Just to have a good pitch to swing and to hit, and I think that has been a big difference for me."
