Worth noting

• Right-hander Shelby Miller threw off the mound at Dodger Stadium on Friday, though manager Mike Matheny wanted to see how Miller responded before making a final decision on whether he would start for the Cardinals on Sunday. Miller exited his last outing prematurely due to back tightness, which has lingered in the days since.

"We've been very optimistic as to how he's progressing, but we'll continue to watch," Matheny said. "We're going to need him to feel pretty good in order to move in the direction that we're going to be able to have him start. We'll just see what he says, see how that's interpreted by the medical team, and then make a decision."

If Miller is unable to go Sunday, the Cardinals will call up a spot starter from the Minors to pitch in his place.

• The Cardinals announced the signing of right-hander Bryan Dobzanski, the team's 29th-round pick in the 2014 First-Year Player Draft. Dobzanski, out of Franklinville, N.J., was a three-sport athlete (baseball, football and wrestling) and had committed to play baseball at the University of Louisville. Dobzanski posted a 0.91 ERA in 46 innings his senior season and averaged 13.3 strikeouts per nine innings.

According to the South Jersey Times, Dobzanski received a $700,000 signing bonus, all but $100,000 of which counted against the Cardinals' Draft bonus pool. Dobzanski will report to the organization's Gulf Coast League affiliate in Jupiter, Fla.

• Matheny acknowledged that closer Trevor Rosenthal was unavailable on Thursday because he threw 41 pitches in an outing Wednesday. Matheny did not divulge Rosenthal's availablity for Friday's game.
