Adams out of lineup with tightness in calf

ST. LOUIS -- Tightness in his left calf kept Matt Adams out of the starting lineup on Wednesday, though he insisted he feels good enough to be available off the bench if needed.

Adams described first feeling the tightness in the final innings of Tuesday's 6-0 win. Postgame treatment and exercises alleviated the discomfort before he left the ballpark, but he woke up on Wednesday again feeling some pull. He alerted the Cardinals to the issue, and manager Mike Matheny opted not to push Adams in the series finale.

"It's something we feel we can get a little ahead of here if we're just a little cautious," Matheny said. "He still may be available late, but going out there from the start is something we're going to stay away from today."

Adams did not hit during batting practice on Wednesday but was on the field shagging fly balls with teammates.

"I feel like I could play today," Adams said. "It's just precautionary. I'm taking it easy, but if they need me to pinch-hit, I'll be ready."

Adams entered the day pacing the National League with 21 multihit games. His .326 batting average ranked fifth in the league.

Taking Adams' place at first base on Wednesday was Allen Craig. That opened starting opportunities for both Peter Bourjos and Jon Jay in the outfield.

Matheny getting ready to lead NL All-Stars

ST. LOUIS -- Major League Baseball has begun its weekly rollout of All-Star voting updates, providing fans with an up-to-date list of who projects to start the Midsummer Classic. For Mike Matheny, it's an added resource for him to use as he prepares for his duties as acting manager of the National League in the July 15 game at Target Field.

Matheny, a first-time All-Star manager, will have the task of filling whichever roster spots aren't taken by players voted in by fans and elected through the player vote. He began talking with MLB officials over the winter to get a better understanding of his responsibilities, and he has also reached out for advice.

"I've asked questions of guys who have been there and done that, and I will continue to do so," Matheny said. "I know there is a lot to learn. Fortunately, I will have a couple of coaches with me who have been there and will use their experience and their wisdom as well."

Matheny has already selected other NL managers to join him as coaches for the All-Star Game, though MLB has not yet released that information. Matheny issued those invitations during the offseason.

In addition to selecting the final players for the roster, Matheny will be charged with choosing which players become Final Vote candidates and who will start on the mound. His own ace, Adam Wainwright, has a strong case for that honor.

"I've been looking at it a little different all season long, looking at guys and keeping track of the kind of seasons some players are having," Matheny said. "It's a great challenge to do what's right for each individual and for each club. I'm looking forward to that challenge."

Worth noting

• Right-hander Keith Butler, a member of the 40-man roster, underwent season-ending Tommy John surgery on Wednesday. Butler had to stop pitching in Triple-A earlier this month due to discomfort in his right elbow, and it was later confirmed that he had a tear of the ulnar collateral ligament. The typical recovery time for this procedure is 12 to 18 months.

• Giants right-hander Matt Cain threw a bullpen session on Wednesday and remains on track to rejoin San Francisco's rotation during the Giants' upcoming visit to St. Louis. Cain is scheduled to pitch on Saturday against righty Michael Wacha. Cain exited his previous start with a strained right hamstring.

• The Yankees have been the first team to employ an exaggerated infield defensive shift on Matt Carpenter this season. Carpenter has not typically been a pull-happy left-handed hitter, but he has grounded balls to the right side with more frequency this season.

"You can't ride one team too much when they do that, because you can't replicate their pitching staff with their pitching staff's stuff and then how they're individually going to pitch a particular hitter," Matheny said.

Carpenter entered Wednesday with a nine-game hitting streak, tied for the longest active such streak in the NL.

• According to the Elias Sports Bureau, Lance Lynn became the first Cardinals pitcher since 1994 to have more strikeouts at the plate (four) than he did of his opponent (two) in a shutout. The last was Bob Tewksbury, who struck out one batter while striking out twice himself in a shutout of the Braves.
