Gonzalez's DL trip comes after his poorest outing of the season, as he allowed eight earned runs on nine hits over five innings on Wednesday.
"When you're not right, a ball doesn't do what you want it to do," Gonzalez said. "It's always good to take a little step back, get together, and get strong. I'll do it day by day, and we'll see what happens. It feels good already. I just went out there today and played catch at 60 feet, and it felt good, nice and loose."
In three June starts against the Orioles, Indians, and Tigers, Gonzalez posted a 10.34 ERA over 15 2/3 innings while registering six walks, six strikeouts, and five home runs allowed. His season ERA sits at 5.49, up from a career mark of 3.97.
• Left-hander Carlos Rodon made his third rehab start on Saturday as he continues to work back from left biceps bursitis. The 24-year-old threw 5 2/3 innings for Triple-A Charlotte, allowing three runs on seven hits with one walk and one strikeout. He threw 89 total pitches, and Renteria indicated on Sunday it's a possibility that Rodon returns after one more rehab outing.
"Physically, he felt good," manager Rick Renteria said. "Still a little elevated, he threw more strikes. He's really close, so hopefully he continues to work on attacking the zone and getting his pitch count up."
• Center fielder Leury Garcia remained out of the starting lineup for a third straight game on Sunday as he continues to deal with a sore left hand. The issue is bruising and inflammation, however, as results from a second X-ray on Saturday came back negative.
