ST. LOUIS -- General manager John Mozeliak confirmed that the Cardinals plan to place Lance Berkman on the 15-day disabled list after the first baseman aggravated a left calf injury in Wednesday's 11-1 win over the Reds.
Taking Berkman's place on the roster will be Skip Schumaker, who is wrapping up his Minor League rehab work with Triple-A Memphis on Thursday. Schumaker will join the club on Friday in Pittsburgh, where the Cardinals begin a six-game, two-city road swing.
Berkman reported feeling "still pretty sore" on Thursday morning, a day after a misstep during his pursuit of a popup caused a recurrence of tightness in his calf. Berkman exited that game early and spoke afterward about the possibility of needing a DL stint in order to ensure that he can move on without compromised health.
The same injury sidelined Berkman for three weeks in 2009.
Mozeliak added that it would be more challenging to carry an unavailable Berkman on the roster -- as the team did last week -- right now, given that the club doesn't have another off-day until April 26. Berkman missed four games from the initial calf strain before returning to the lineup on Tuesday.
Berkman's injury prompted the Cardinals to revisit Schumaker's rehab timetable. Just two days ago, manager Mike Matheny said that a weekend return would "probably be too early" for Schumaker, who has been out with a right oblique strain since mid-March.
There was also precedent for keeping conservative with Schumaker's track. Before joining Memphis on Sunday, Schumaker noted that he did not want to repeat last year's issue of rushing through a rehab assignment and then coming back at less than 100 percent.
Sharing the same concern, Mozeliak spoke with Schumaker before changing course. Schumaker told Mozeliak that he feels ready.
"When you look at where he's at -- and we checked with him -- we can be careful without being overly demanding with what his role will be when he first comes back," Mozeliak said. "We felt like this was the safest move to do."
Thursday's game was Schumaker's fourth game with Memphis. He made his second start at second base and was slated to play a full nine innings for the first time. Schumaker's other two appearances came in the outfield, and he began the day with three hits in his first 10 at-bats.
The Cardinals did consider calling up Triple-A first baseman Matt Adams, but with Matt Carpenter off to such a hot start, the team was not likely to have enough playing time to warrant Adams' addition. St. Louis plans to use Carpenter as the team's starting first baseman during Berkman's absence.
Carpenter entered Thursday with 11 RBIs and nine hits in 24 at-bats.
"Right now, with the way he's playing, give him a shot," Mozeliak said.
Jay injures shoulder after running into wall
ST. LOUIS -- Jon Jay exited the Cardinals' clubhouse on Thursday afternoon, his right arm in a sling following a late-inning collision with the outfield wall during the Cardinals' 6-3 loss to the Reds.
Though X-rays showed no structural damage, Jay was in evident discomfort postgame. Even before he put on the sling, he walked around without extending his right arm. He dug through his locker and put on his shirt only using his left hand.
The Cardinals announced Jay's status as day to day, though the club will likely have a better idea of the severity of the injury, which was classified as a right shoulder sprain, on Friday. If Jay does end up on the disabled list, it would make the first such stint of his career.
Jay sustained the injury in the seventh, as he tracked Drew Stubbs' fly ball to center. He ran awkwardly into the wall as Stubbs' ball cleared the fence. Jay stumbled as he came down and was lifted from the game at the end of the frame.
"I was about to make my jump [at the wall] right there," Jay explained. "I miscalculated my steps."
With Skip Schumaker already set to come off the disabled list on Friday, the Cardinals do have ample outfield depth to be able to carry them for however long it is that Jay will be sidelined. If the club does put Jay on the DL and wants to fill his spot with another outfielder, Adron Chambers would likely be the one. He is the only other outfielder on the 40-man roster who is not already with the big league club.
One move the Cardinals could have made is having Carlos Beltran shift from right field to center. Instead, that center-field position will be assumed by Schumaker, Erik Komatsu or Shane Robinson.
Eight Cardinals listed on All-Star ballot
ST. LOUIS -- Major League Baseball unveiled the 2012 All-Star Game ballot on Thursday, one day in advance of the launch of online voting at MLB.com. Of the eight Cardinals position players listed on the ballot, five are already multi-time All-Stars.
That includes six-time All-Stars Carlos Beltran and Lance Berkman, as well as five-time participant Matt Holliday. Beltran has jumped out to the best start of those three. He entered Thursday's series finale leading the team in home runs (five), runs scored (12), stolen bases (three), walks (eight) and on-base percentage (.460).
Third baseman David Freese and catcher Yadier Molina are also expected to get strong consideration in the voting, which will take place both online and in each ballpark. In-stadium voting at Busch Stadium begins on April 29 and continues through June 15. Online voting closes at 10:59 p.m. CT on June 28.
Rounding out the Cardinals' ballot representatives are Rafael Furcal, Jon Jay and Tyler Greene. Daniel Descalso, who has earned most of the starts at second this year, is not listed.
The National League team will be managed by retired Cardinals manager Tony La Russa, who has already agreed to return to the dugout for that game.
Craig nearing Minor League rehab assignment
ST. LOUIS -- Allen Craig resumed playing in extended spring training games on Wednesday and has a chance, general manager John Mozeliak said, of beginning an official Minor League rehab assignment by the weekend.
A position player can remain on a rehab assignment for a maximum of 20 days. Craig's participation in extended spring games does not count against that clock.
At this point, Craig (right knee surgery) is only hitting in these games. He's expected to add the defensive side in early next week.
In other injury news:
Scott Linebrink (right shoulder capsulitis) is still days away from taking the next step in his rehab program, which would be to pitch off a mound. His throwing work right now continues to be on flat ground.
The status of Chris Carpenter (nerve irritation) remains unchanged. He continues to work through strengthening exercises without a set date as to when he will be able to begin throwing again.
Cardinals trio receives GIBBY Awards
ST. LOUIS -- Lance Berkman, David Freese and general manager John Mozeliak each received their 2011 GIBBY (Greatness in Baseball Yearly) Awards during a pregame ceremony on Thursday afternoon. Major League Baseball's GIBBY winners are selected annually based on votes by fans at MLB.com, media, front-office personnel and MLB alumni.
Berkman was named baseball's comeback player of the year following a 2010 season in which injuries hampered his performance. In his first year with the Cardinals, Berkman rebounded to hit .301 with 31 homers and 94 RBIs.
Mozeliak earned Executive of the Year honors in recognition of the work he did to construct a championship roster. Freese was voted the Most Valuable Player of the postseason. His ninth-inning triple to extend Game 6 of the World Series was selected as the top postseason moment.
Top pitching prospect Shelby Miller collected his first Triple-A win on Wednesday. Though he needed 94 pitches to get through five innings, Miller (1-2) limited New Orleans to one run on five hits and four walks. He struck out nine.
With his stolen base on Wednesday, Tyler Greene improved to 17-for-17 in career stolen-base attempts. No Cardinals player since 1951 has begun his career with a longer perfect streak.
The Cardinals announced on Thursday that they will be holding their third annual Green Week from April 24-29. The kickoff event will be an e-cycling drive, where fans are asked to drop off unwanted electronic equipment in the Ballpark Village Parking lot. Fans who make a donation will receive a discount on Cardinals tickets.
There will also be collections at the Busch Stadium gates for shoes and cell phones from April 27-29. During that weekend series against the Brewers, the Cardinals will also have volunteers collecting recyclables in the stadium. For more information about Green Week events, visit cardinals.com/green.
Manager Mike Matheny opted to keep third baseman David Freese and catcher Yadier Molina out of the lineup on Thursday in order to give both a break during this current stretch of nine games in nine days. Remaining in the lineup was Matt Holliday, who told Matheny he wants to hit his way out of his early-season slump. Plenty of lousy luck has played a role in Holliday's 10-for-55 start.
The Cardinals are scheduled to face right-hander Charlie Morton, right-hander Kevin Correia and left-hander Erik Bedard in their upcoming series in Pittsburgh.
Cardinals Minor League pitcher Jose Pasen has been suspended 50 games for violating the Minor League Drug Prevention and Treatment Program. Major League Baseball issued a release on Thursday that stated Pasen tested positive for a performance-enhancing substance called Nandrolone.
Pasen, 21, is on the roster of short-season Batavia (NY), which does not begin its season until June. Pasen went 4-4 with a 4.45 ERA in 11 starts for rookie league Johnson City (Tenn.) last year. Drafted out of the Dominican Republic, Pasen was converted from an outfielder to a pitcher in 2008.
