Kyle Kendrick scratched with shoulder soreness

Kyle Kendrick has never missed a start in his major league career. He's never been on the disabled list - not in the major leagues or in the minor leagues, either.

But the durable Kendrick has been battling shoulder soreness, Phillies manager Ryne Sandberg said on Tuesday, and he will not make his next scheduled turn in the rotation.

Kendrick had an MRI on his shoulder on Tuesday. Zach Miner will start in his place on Wednesday night against the Miami Marlins.

"He's had a little discomfort for a few weeks but was still able to pitch," Sandberg said. "He was still able to do his exercises. That's why it's a precautionary move just to free his mind of anything. He actually said he was still able to pitch now."

Kendrick's 6.91 ERA is the worst in the National League since the All-Star break among regular starters in the league. (Among NL pitchers with at least 40 innings since the break, only Jake Westbrook, with a 7.97 ERA, has been worse; but Westbrook has also been used as a reliever, too).

Kendrick had a sparkling 3.22 ERA after his first 13 starts of the 2013 season. He allowed two runs or fewer in 11 of his first 16 starts.

 But he took an ugly turn when spring turned to summer: Kendrick has allowed four or more runs in nine of his last 14 starts.

Sandberg opined that Kendrick's two-seamer was flat following a loss on Friday in Washington. On Tuesday, he was asked if the shoulder woes are to blame for Kendrick's second half slide.

"It's hard to tell; That's a possibility," Sandberg said. "It could have had something to do with it. His velocity was still good. He was still able to throw a number of pitches and still pitch with it. It wasn't a thing that was a concern the last few weeks. At this stage of the season, the organization just felt for his peace of mind to be checked out."

Kendrick was scheduled to meet with Phils team doctor Michael Ciccotti on Tuesday.

The 29-year-old Kendrick is in the second year of a two-year, $7.5 million deal. His is eligible for salary arbitration this winter.
