Berkman activated; Robinson sent to Triple-A

ST. LOUIS -- The Cardinals optioned outfielder Shane Robinson to Triple-A Memphis on Sunday to open up a spot on the 25-man roster for Lance Berkman, who had been on the disabled list with a left calf strain since April 19.

Berkman, who missed 21 games while he nursed the injury, hit fifth and played first base for St. Louis on Sunday. He finished 1-for-5 with a single and three strikeouts.

"I was pretty pleased with the at-bats for not having been in there," Berkman said, when asked about his timing. "It's just going to take some time."

He said he felt no discomfort in his left calf during his nine innings on the field.

Robinson will join Memphis on Monday after enjoying Mother's Day in St. Louis with his wife, Jessica, who recently gave birth to the couple's first child, Tinley.

Robinson was squeezed from a roster spot despite playing quite well during his time with the Cardinals. In addition to playing a solid center field, Robinson hit .311 in 23 games. He made eight starts.

"Shane plays a fantastic outfield and has done a good job putting together great at-bats in the limited time he gets," manager Mike Matheny said. "I was real impressed with him."

Robinson is in line to be the first player called up should the Cardinals need to replace an outfielder. He is likely to accrue regular playing time with Memphis.

The Cards went 11-10 during Berkman's most recent absence. Before landing on the DL, Berkman collected eight hits in 23 at-bats.

Seven Cards use pink bats for Mother's Day

ST. LOUIS -- In conjunction with Mother's Day, Major League Baseball raised awareness for breast cancer on Sunday by prominently incorporating the color pink in each of the 15 games played.

At Busch Stadium, the Cardinals and Braves each posted pink lineup cards in their respective dugouts. Seven Cardinals players -- Jon Jay, Tyler Greene, Tony Cruz, Rafael Furcal, Lance Berkman, Matt Holliday and Jaime Garcia -- agreed to use pink bats, each stamped with the MLB breast cancer awareness logo.

Those bats will be auctioned off on MLB.com to raise funds for the Susan G. Komen for the Cure, which is the largest breast cancer foundation in the world. Among its initiatives is helping to fund awareness, research and treatment of the disease.

Pink bats, identical to the ones swung by Major Leaguers on Sunday, are also available for purchase at the MLB.com Shop. The cost is $69.99 per bat, with $10 of each sale going to Komen for the Cure.

All players and on-field personnel will attach pink ribbons to their uniforms on Sunday. Some will also be wearing pink wristbands, pink batting gloves, pink wrist protectors and pink Phiten Titanium necklaces/bracelets. Though he's unlikely to take the field, Garcia will also be donning pink cleats.

Worth noting

• After starting each of the first 33 games this season, Matt Holliday was out of the lineup on Sunday. Taking his place in left field was Allen Craig, who last played the position in Game 7 of the World Series.

• Braves third baseman Chipper Jones, who announced he will retire after the 2012 season, was honored by the Cardinals on Sunday, his last regular-season game at Busch Stadium. Rafael Furcal, a former teammate of Jones', presented Jones with a photo signed by various members of the organization. Adam Wainwright, a Georgia native and former Braves farmhand, handed Jones an autographed Stan Musial jersey.

Jones left the field to a standing ovation, tipping his cap several times during the ceremony.

"I've always enjoyed coming here, and the fan base in St. Louis is part of that," Jones said. "You can have an opposing player hit three home runs against the Cardinals, and these fans will give him an ovation for a job well done. It's nice to play in a city where good baseball is appreciated. Other teams enjoy coming in here to play because they get to entertain some pretty intelligent fans."

• Because the game will be televised on ESPN, the Cardinals-Cubs contest on Monday will begin at 6:05 p.m. CT. That is 70 minutes earlier than the normal weeknight start time at Busch Stadium.

• Manager Mike Matheny reiterated on Sunday that he will consider using Carlos Beltran in center field when he needs to give Jon Jay a day off. Beltran has made 1,555 career starts in center field, but none since 2010.

• J.C. Romero twisted his right ankle slightly while struggling to grip his cleat in the dirt mound on Saturday but said that his ankle feels fine. He was briefly checked on by Matheny and trainer Greg Hauck.
