Orioles pitching prospect Dylan Bundy was lined up to pitch to All-Star catcher Matt Wieters Tuesday as the latter made his first rehab appearance for the Double-A Bowie Baysox.
Instead, he was scratched and spent the day getting his sore right shoulder looked at in advance of an MRI Wednesday to determine whether there is any structural damage.
Bundy said Tuesday that "soreness in one of the cuff muscles" cropped up the day after his most recent start, when he struck out five in four scoreless innings — his longest outing of the season — last Thursday in Trenton, N.J.
The following day, and throughout his preparation for Tuesday's scheduled start, the soreness persisted.
"I did all the throwing," Bundy said. "I threw my bullpen like I would normally, and I kept getting treatment on it, trying to get it better for this start. Yesterday, I just told the guys, the pitching coach [Alan Mills] and trainer [Pat Wesley] that I couldn't go today."
Still, Bundy said he doesn't "think it's anything too serious."
"Fingers crossed, and we'll see what it says tomorrow," he said.
The shoulder issue, which Bundy said he hoped could be resolved with some anti-inflammatory medication, is the latest setback in a career that was on the fast track to major league stardom in 2012.
Bundy debuted in Class-A Delmarva that year and spent September in the major leagues, making two appearances without allowing a run.
But all of 2013 was lost to an elbow injury that required Tommy John surgery, and he made nine starts between short-season Class-A Aberdeen and High Class-A Frederick in 2014. Bundy was improved throughout that summer before a strained lat muscle sidelined him from mid-August until the end of the minor league season.
Through eight starts (22 innings) for the Baysox this year, Bundy was 0-3 with a 3.68 ERA, 25 strikeouts and just five walks.
Just last week, manager Buck Showalter said Bundy could skip Triple-A if he was able to help the major league team straight from Bowie. On Tuesday, Bundy said his frustration level was "pretty high."
"I was getting my [velocity] back, getting my command where I wanted it, then you've got this," Bundy said. "It's kind of like starting from scratch all over again. … That's kind of the way I'm looking at it. I'm just getting going, on a roll, and I had this little setback. Hopefully it's nothing more than a week or two."
Bowie pitching coach Alan Mills said Bundy's velocity had risen from the low-90s in April to mid-to-high 90s recently, and that they were working to harness that by consistently creating a downhill plane for the ball.
"The only thing I'm really disappointed about was where he is, he got the velocity back up," Mills said. "Now, he's out. I was going to try to have the velocity and create that [downward] angle, which would benefit him in the future. But I don't see it as a major setback, and hopefully, he'll be back with us soon."
