• Matheny reported that Trevor Rosenthal (strained right groin) is improving and has increased the intensity of his workouts. It has not yet been announced when Rosenthal will make his Grapefruit League debut. Rosenthal, who last pitched on Tuesday, will need to throw on the side before the Cardinals will allow him to make that first game appearance.
• In advance of his first spring start, on Thursday, Adam Wainwright threw his third batting-practice session of the spring on Saturday. He simulated two innings of work by taking a rest halfway through. The Cardinals plan to have Wainwright start five Grapefruit League games before he takes the mound on Opening Day.
• Peralta's next spring appearance will be on Monday, when the Cardinals travel to Lakeland, Fla., to face the Tigers. Peralta spent four seasons with Detroit before signing as a free agent with St. Louis in November. Matheny has already discussed those travel plans with Peralta, who agreed to the assignment.
• Infielder Greg Garcia exited Saturday's game in the seventh inning with a cramp in his left hamstring. Matheny noticed that Garcia looked uncomfortable on defense in the sixth and again when he reached first in the seventh after being hit in the back by a pitch. After advancing to second, Garcia was removed for a pinch-hitter.
"It was just something that was kind of out of whack," Matheny said. "The trainers seemed to be able to line him up a little. It feels better already. ... He's put together some tough at-bats. He'll scrap in there at the plate. He plays good solid defense. He's a very diverse player."
