"Hopefully it's not that much longer," said Putz, who is eligible to come off the DL May 19. "I feel good. It was coming out good today. We'll see how it feels tomorrow."
• Right-hander Daniel Hudson, who is trying to come back from his second Tommy John surgery in as many years, threw a bullpen session and threw his slider for the first time post-surgery.
• Top prospect Archie Bradley, who is on the Minor League DL with a mild flexor strain in his right elbow, will soon be re-examined and could be throwing again soon.
"It's my understanding that it feels much better, but he hasn't thrown," Gibson said. "I think he'll start up pretty soon after he sees the doctor. That's what our hope is."
