• Shelby Miller, who was officially named the team's fifth starter on Monday, will pitch in a Triple-A game on Saturday before joining the club in Phoenix for the season opener Monday against the D-backs. The Cardinals plan to decide after that outing whether to have Miller pitch the fifth game of the season or to skip his spot in the rotation the first time it comes up.
"To me, I think it's going to depend, one, on how everybody's outings go the first time through and also how things go that last start here in Triple-A," manager Mike Matheny said of the decision. "It's all about how well it goes and how he feels and how the rest of the guys feel as well. I just don't want to say one way or the other right now."
• Though infielder Greg Garcia is still in Major League camp, the Cardinals have opted to give an Opening Day roster spot to Ryan Jackson during David Freese's stint on the disabled list. Jackson, who was already on the team's 40-man roster, will provide depth at second, short and third. Garcia is not on the 40-man roster.
"When we sent him out originally, Mike and the staff gave him some instruction that he really took to heart and he's had a nice camp down there," general manager John Mozeliak said of Jackson. "We really feel confident about bringing him back."
• Lefty reliever Sam Freeman was optioned to Triple-A Memphis on Tuesday, two days after he returned to the mound following a left shoulder impingement injury. As a result of that setback, Freeman made only two appearances in Grapefruit League games.
• The Cardinals are inviting fans to vote on whether the Cardinals will wear red or blue caps on the road this season. Votes can be cast at cardinals.com/redvsblue through Wednesday. On Thursday, there will be an additional Twitter vote. Last year, the Cardinals wore blue caps on the road and red caps for home games.
