JUPITER, Fla. – Cardinals pitching prospect Shelby Miller is dealing with tightness and soreness in his right shoulder and won’t throw from the mound for a couple days.
Miller, who is competing with Trevor Rosenthal and Joe Kelly for the No. 5 starters spot in the Cardinals rotation, alerted the team of soreness following his last throw.
“We’re going to give him a day to kind of give him time in the training room and work on that,” said manager Mike Matheny. “But if you’re following it and you see that he hasn’t been out there, he’s just going to get another day or so. We’re not too concerned, just going to give him a little more time. It’s more preventative right now.”
Miller posted a 1.32 ERA in six games with the Cardinals after making his Major League debut in September. He appeared in two games in the NLCS against the San Francisco Giants but allowed two earned runs in 3 1/3 innings.
The 22-year-old was drafted No. 19 overall by the Cardinals in the 2009 MLB Draft out of high school in Texas. He was ranked as the No. 6 overall prospect in baseball by Baseball America for the 2013 season.
“We’re just going to go slow,” Matheny said. “We have all kinds of time. He’s probably still going to be out here playing catch and doing all the drills. We just want to keep him from going hot off the mound for a couple days and see how it feels and once again, this isn’t a major issue as much as just trying to get ahead of something. He’s got lots of time to build up his pitch count.”
Miller could start the season in the Cardinals bullpen if he doesn’t win the fifth starters spot.
