The Cardinals put Jay on a modified spring program, which also includes a mapping of different checkpoints that the training staff expects Jay to hit during camp. It was created with the intent of getting Jay ready not for the spring opener, but for Opening Day a month later.
"He's getting stronger and everything is measuring out well," Matheny said. "He did some more this morning, just pushed it a little bit further. He's taking gradual steps. Everything we've heard is positive."
Here is a rundown of other items of interest from Day 10 at Cardinals camp:
• While nearby areas dealt with flooding issues following Saturday's torrential downpours, the backfields at the Cardinals' complex were suitable for play on Sunday without any delay in schedule. In addition to the built-in drainage system, the grounds crew used drying machines to address the rain-soaked fields.
• The club resumed sessions of live batting practice and had a dozen pitchers take the mound to face hitters. That group included Michael Wacha, Tim Cooney, Jaime Garcia, John Gast, Zach Petrick, Mike Mayers, Matt Belisle, Randy Choate, Seth Maness, Kevin Siegrist, Miguel Socolovich and Nick Greenwood. Starting pitchers like Wacha and Garcia simulated an inning break by throwing half of their pitches, sitting down for a bit and then returning to the mound to finish their session.
• Though the Cardinals signed Mark Reynolds primarily to provide protection at first base, much of Reynolds' defensive repetitions thus far have come at third. Reynolds, who will also serve as the backup to Matt Carpenter, asked the Cardinals to structure his work that way since third base is a more demanding position for him.
• Prior to the workout, players on the team's 40-man roster listened to a Major League Baseball Players Association presentation on the issue of domestic abuse. The players will also have a meeting with the MLBPA later in spring to discuss other general issues and protocol.
• Players and staff stuck around the complex a little later than usual to sign autographs for season-ticket holders inside Roger Dean Stadium. The event took about an hour.
