ST. LOUIS -- Still limited by the right shoulder he sprained last month, Jon Jay is headed to the 15-day disabled list, hopeful that the down time will allow the lingering discomfort to subside for good.
Jay suffered the sprain on April 19, when he ran into the center-field wall. He remained out of the starting lineup for six games, while letting the bruise heal, and received a cortisone injection to assist in the healing process. He returned on April 27, but admitted on Tuesday that, even then, his shoulder never was 100 percent right.
"I still felt it," Jay said. "It was just one of those things where I wanted to be out there and try as best I could. It's gotten to the point where it's better to take a step back now, get some rest and then go from there."
The last week was a turning point for Jay, who said the discomfort began to increase during the team's recent road trip. It primarily affected Jay's ability to follow through on his swing, and that has led to a recent dip in production.
Jay hit .400 in his first 12 games back after his initial period of rest. Nineteen of those 20 hits, though, were singles, a sign that Jay's shoulder was preventing him from getting much power in his swing.
In his last 12 at-bats, Jay recorded only one hit.
"It's one of those things where I want to be out there, but if I'm not helping the team the way that I can contribute, then it's tough," said Jay, who has never previously been on the DL. "It got to the point where I'm not helping the team."
The Cardinals called up Shane Robinson to take Jay's roster spot, though the majority of center-field playing time is likely to fall on the shoulders of Skip Schumaker during Jay's absence. Carlos Beltran can also play the position, but the Cardinals might be more hesitant to move him from right field now that Beltran is dealing with a sore right knee.
There are no immediate plans for Jay to have another magnetic resonance imaging test. The MRI he had on his shoulder in April revealed no structural damage. Jay will not travel with the team during the next road trip.
Sore knee keeps Beltran on bench
ST. LOUIS -- Carlos Beltran remained out of the lineup for the second straight day while nursing a "sore and stiff" right knee, as he described it. Added manager Mike Matheny, "He wasn't completely ready to go."
Beltran, as he was on Monday, is available to pinch-hit on Tuesday, and the Cardinals are optimistic that the right fielder will rejoin their lineup during the team's next series.
According to Matheny, Beltran is not dealing with much swelling in his knee, which he had surgery on prior to the 2010 season. The issue is simply soreness, something that the Cardinals anticipated Beltran likely would deal with at some point during the year.
The Cardinals' medical staff was scheduled to reexamine the knee on Tuesday, but didn't expect to find any serious issues.
Said Matheny: "They're all pretty confident that we're on the front of it here."
Berkman scratch not related to injury
ST. LOUIS -- Changing his mind late on Tuesday morning, manager Mike Matheny pulled Lance Berkman out of the starting lineup in order to make room for both David Freese and Matt Carpenter to play.
Following the Cardinals' 7-6 win over the Cubs, Matheny explained that the decision to make the switch had little to do with Berkman ailing and more because he wanted to find at-bats for Freese.
"Early on, when I got here this morning, I was still trying to figure out if we could get [Freese] in," said Matheny, whose first lineup had Berkman playing first and Carpenter starting at third. "I made the late scratch to get David in and to give Lance a day on a pitcher he's had a little bit of a tough time with."
Berkman entered the day 7-for-34 against Cubs starter Paul Maholm.
The Cardinals have been prepared to liberally insert time off for Berkman, who just came off the disabled list on Sunday. He missed more than three weeks nursing a left calf strain. Berkman confirmed on Monday that he has had no recent recurrence of discomfort in his leg.
"I feel good," he said. "I'm ready to play. Part of being a veteran guy and putting up numbers to help the team is just being available to play every day. I feel very comfortable and confident that I can do that, particularly now that I have this calf thing out of the way."
Berkman started on both Sunday and Monday, going 3-for-9 with one RBI.
Carpenter, who was initially slated to start at third base, moved across the diamond to take Berkman's spot. He delivered a key solo homer for the team in the eighth inning. Freese was inserted to play third and bat fifth. He finished 0-for-5.
Freese is hitless in his last 16 at-bats and has grounded into four double plays during that span. His batting average has dropped to a season-low .272.
"He's been hitting some balls hard and not getting anything to go, and now he's fighting himself," Matheny said. "He just has to stop and breathe a little bit. That's part of the reason why I wanted to give him a day [off]. But some guys just can't wait to get back in there. Today was one of those days for David.
"We just needed to keep pointing out the positives. He's hitting some balls hard. It's just a tough time for him right now."
Robinson returns to St. Louis; luggage doesn't
ST. LOUIS -- Shane Robinson went 3-for-4 and scored two runs in Triple-A Memphis' loss to Colorado Springs on Monday night. Afterward, he was summoned into the office of manager Ron "Pop" Warner.
"Appreciate you coming up," Warner said. He then informed Robinson to pack up. He was headed back to Busch Stadium.
Optioned to the Minors only two days ago, Robinson rejoined the Cardinals on Tuesday. He was needed after the Cardinals had to place center fielder Jon Jay on the 15-day disabled list with a right shoulder sprain.
Though Robinson made it in time for the team's afternoon game against the Cubs, the same couldn't be said for Robinson's belongings. While he took a direct Delta flight from Memphis to St. Louis, his two bags were mistakenly placed on a plane headed to Atlanta.
Robinson expects to get the two bags back before the team boards a flight to San Francisco later on Tuesday. He was, however, forced to scramble for some equipment for the game.
"It's been pretty chaotic," Robinson said. "I am trying to get everything back together and figure out what I need. I'm going to have to walk around and see [whose glove] feels as close to mine."
Fortunately, Robinson wasn't left without bats. He had ordered a new shipment a few weeks ago, and they happened to arrive in St. Louis after he had already departed for Memphis.
Manager Mike Matheny said the Cardinals have identified something in Victor Marte's pre-pitch routine and delivery that, when fixed, should cut back on the leads baserunners are getting off of him. Marte has allowed three stolen bases in his last two appearances (1 2/3 innings).
"We've picked something up that they're keying off of, and we addressed that [Monday] night," Matheny said. "That's hard for [the catcher] to do anything about it with the jumps they're getting."
Mitchell Boggs was not available out of the bullpen on Tuesday after throwing a season-high 46 pitches Monday night. The last time he threw that many pitches in a game for the Cardinals was in 2009, when he was still being used as a starter.
Boggs hasn't been as sharp this month as he was in April, and he hasn't had much luck either. After allowing four hits, one walk and one earned run in 10 1/3 innings in April, Boggs has given up 11 hits, four earned runs and five walks in 5 2/3 May innings.
"Those things tend to happen when you're falling behind guys and letting them hang around," Boggs said of some of the bad luck. "I think as long as I stay aggressive in the strike zone, I'll be fine. But when you start nibbling, those balls tend to fall a little more than they usually do."
For the second time this year, the Cardinals' Triple-A Memphis has lost nine in a row. Picking up the loss for Memphis on Monday was starter Joe Kelly, who allowed four runs on 11 hits in 6 1/3 innings.
Right-hander Scott Linebrink (right shoulder capsulitis) resumed playing catch on Tuesday. Linebrink was recently shut down after additional inflammation became bothersome in his right shoulder. He will work his way through several days of catch and long toss before returning to the mound.
