Molina playing nearly every day in return from DL

MILWAUKEE -- When Yadier Molina returned last Thursday after a stint on the disabled list with a right knee sprain, there was expected to be a scheduled plan of rest for the All-Star catcher.

But Molina's name was written into manager Mike Matheny's lineup for the fifth consecutive day on Wednesday against the Brewers, and for the sixth time in seven days since his return.

"He's going to get a day off when he needs a day off," Matheny said. "We've had a lot of conversation when we had younger players. We do a lot of the decision making for them. He's a grown man, these guys know what they need, they know where they are. We're all going in the same direction, trying to go to the same common goal. They don't want to be injured, we don't want them injured, but the guys that have been doing this for a long time, they're going to be the best source of information that we have."

Before Molina's first game back, Cardinals general manager John Mozeliak said the team needed to be cautious with its catcher.

"We just have to be smart," Mozeliak said at the time. "Obviously, I think you just look at how things go [in Molina's first game back], and that might dictate how things look the next day. But prioritize rest certainly in the first seven days back. We have to be cognizant of that and think through it. … Clearly, we need to make sure there are breaks in his workload."

But Matheny said a constant flow of communication between the Cardinals' medical staff, Molina and himself is what has allowed them to feel comfortable putting Molina on the field.

"We're getting clearance from our medical people that he's responding very well, and he's telling us that he feels good," Matheny said. "And that's what we're going to have to go with, and we're going to trust that.

"You've got to trust guys, and, once again, they're capable of helping make that decision. We as a staff need to step in and see what we see, we have very talented medical people that give us medical backing, that give us medical suggestions. We take all that information in, but the player also has a say in what goes on."

Molina has been scorching hot since returning to the Cardinals' lineup for their six-game road trip through Chicago and Milwaukee, which ends on Wednesday at Miller Park. Molina entered Wednesday 10-for-18 with five doubles and two home runs on the trip, and he racked up six hits in the first two games against the Brewers on Monday and Tuesday.

The Cardinals, who went 6-8 in Molina's absence, entered Wednesday 4-1 in the catcher's starts since his return.

Milwaukee finally cooled Molina down, as he went 0-for-4, but the Cardinals won their third straight series with an 8-6 victory in the rubber game.

"I feel good," Molina said. "We've been winning and that's important."

Molina entered Wednesday leading the National League in batting average (.336), and was second in doubles (35) behind teammate Matt Carpenter and second in all of baseball in innings caught (851) despite his time on the DL.

"It might not look how everybody else wants it to look, but that's not our concern. Even a little bit," Matheny said. "It's got to be what's best for our player, what's best for our team.

"We've been trying to conserve this time for hopefully an extra month. So it's going to be more feel now than it's going to be anything else. [Early in the season] we gave Carlos [Beltran] more rest than he's ever had, because we saw last year and it looks like he got tired at the end. So let's conserve so we have a strong August, strong September, and he played along well. He bought into that plan. We're in a fight, we're in a push, and he's just going to let us know if something physically isn't going to allow him to be out there. It's not saving now. This is the time to put it all together."

Mujica checked by trainers, stays in game

MILWAUKEE -- In the bottom of the ninth inning of Wednesday's 8-6 win over the Brewers, Cardinals manager Mike Matheny and members of the training staff did something that made St. Louis fans hold their breath -- they ran out to check on closer Edward Mujica.

Mujica, who sat out the Cardinals' entire weekend series in Chicago with arm fatigue, said after the game that he has been battling an issue behind his right shoulder under his trapezius.

Matheny said his closer just did not look right.

"Yeah, he looked like he just didn't feel right, so you see that you've got to go find out," Matheny said. "We're just going to continue to keep our eyes on it and we'll give him days when we can. We've given him a few. Let the doctors -- the medical team -- get their hands on him again, just keep working on him and see what we have to deal with."

The right-hander went on to record the final two outs for his 33rd save, and he looked good doing so, other than on a Logan Schafer home run three pitches after the mound visit.

"It's under my trap and my back," said Mujica, who sported a large bag of ice on his right shoulder. "Right now it might be a little stiff with the ice and everything, but, you know, I'm not concerned about it."

Mujica has recorded 33 of the Cardinals' 35 saves this season. He sounded confident he would be in every closing situation for the rest of the year.

"If the trainer starts treating me better, I can go almost two more months," Mujica said with a laugh. "We'll see how I'm going to feel tomorrow."

Radio voice Shannon resting comfortably after surgery

MILWAUKEE -- As reported by the Cardinals' flagship radio station KMOX, Cardinals broadcaster Mike Shannon is recovering well this week after undergoing a successful surgical procedure on Monday to replace his aorta valve.

The surgery had been planned for some time, and according to the station, Shannon is expected to make a complete recovery. He says through family that he expects to return to the broadcast booth before the end of the regular season.

"I would like to thank everyone for their prayers, heartfelt well-wishes and kind words. It means a lot to me," Shannon said to KMOX. "I'm looking forward to getting back in the booth and back to the game I love."

A rotation of Cardinals announcers will fill in for Shannon during his recovery. Al Hrabosky, Rick Horton and Mike Claiborne will be joining John Rooney in the radio booth through Sept. 23, the date Shannon plans to return.

Shannon played for the Cardinals from 1962-70 and won two World Series championships with the team (1964 and '67). He has been in the Cardinals' radio booth since 1972.

Worth noting

• Carpenter and Allen Craig were back in the Cardinals' lineup on Wednesday after a day off on Tuesday, hitting first and fourth, respectively. Kolten Wong was also out of the lineup after going 5-for-10 with three stolen bases in the last two games.

Craig went 2-for-4 with an RBI double and his 12th home run of the year, a solo shot, in the win to get to 90 RBIs on the season, while Carpenter went 1-for-4 with a sacrifice fly.

• Matheny said he really did not want to use left-handed reliever Tyler Lyons in Tuesday's 6-3 loss, but he said Michael Wacha would be available on Wednesday.

"Every day it seems like right now, we're going through mass evaluation with all of our young relievers in terms of where they are," Matheny said. "We needed Tyler to step in for a couple yesterday, he did a really nice job."
