Royals’ Danny Duffy is rehabbing from injury ... and providing expert game commentary

As the Royals embarked on a nine-game road trip on the West Coast, starting pitcher Danny Duffy remained back in Kansas City, focusing on his rehab from a strained oblique muscle.

On Friday, Duffy threw his latest side session at Kauffman Stadium. He will throw again on Sunday, Royals manager Ned Yost said, and he could face some live hitters during a side session on Tuesday at Kauffman Stadium. For now, he appears to be slightly ahead of schedule. He was expected to miss closer to six to eight weeks after going on the disabled list on May 30.

“We’ll see how he’s doing,” Yost said on Friday. “He’s making progress.”

The injury, though, has allowed Duffy one perk: He’s live-tweeted the action during the Royals’ five-game winning streak.

In the last week, Duffy has weighed in on everything from Matt Strahm’s sterling first career start …

… to Ian Kennedy’s penchant for drawing walks during interleague games (Kennedy actually leads all active major-league pitchers in walks drawn) …

… to Mike Moustakas’ continued power surge (at 18 and counting as of Friday afternoon) …

… to the general quality of the Royals’ play during this road trip …

The in-game tweets will likely end when the Royals return to Kansas City on Monday and Duffy rejoins his teammates at Kauffman Stadium. So enjoy for now.

Karns expected to resume throwing

After the discomfort in his right arm lingered, injured starter Nathan Karns headed back to the doctor on Wednesday for additional tests, Royals manager Ned Yost revealed on Friday afternoon.

Yost described the decision as precautionary, but Karns has been shut down from throwing for a number of days. He is expected to resume a throwing program when the Royals return to Kansas City next week.

“He went to see a doctor two days ago and everything checked out,” Yost said. “When we get back home, he’ll start playing catch again.”

In his first season with the Royals, Karns posted a 3.43 ERA in eight starts before going on the 10-day disabled list on May 24, retroactive to May 21. The stint came after he felt stiffness in his forearm during a start in Minnesota on May 19. Karns later underwent tests, which revealed fluid near his elbow but no structural damage. The club expected his stay on the disabled list to be brief. But the soreness and discomfort has failed to dissipate, causing him to miss close to a month.
