Walden has a muscle strain in his throwing shoulder and will be out 6-to-10 weeks, USA Today's Bob Nightengale reports. This is the kind of injury where timetables should be given little credence, but nonetheless, it seems like Walden could bout until around the All-Star break. Seth Maness and Kevin Siegrist will now do their best to take the ball in the eighth inning depending on matchups and get it to Trevor Rosenthal in the ninth.

Walden (biceps) will seek a second opinion this week to determine the next step in his rehab process, Jenifer Langosch of MLB.com reports. The current diagnosis for Walden is right biceps inflammation, but the team wants another doctor to look at Walden's MRI before plotting out a course of action for his rehab. With Walden's status in limbo, the Cardinals will likely lean on the tandem of Seth Maness and Kevin Siegrist to handle setup duties.

Walden was placed on the 15-day disabled list Sunday with right biceps inflammation. The injury is tough break for Walden, who had emerged as the Cardinals' top setup ace after compiling a 0.87 ERA, 1.06 WHIP, and 12:4 K:BB ratio over his first 12 appearances, covering 10.1 innings. Walden's DL placement will be retroactive to April 29, allowing him to be activated as soon as May 15 if he recovers quickly. The Cardinals added Sam Tuivailala from Triple-A Memphis to restore some depth in the bullpen while Walden remains unavailable.

Walden got the save Sunday night against the Reds because Trevor Rosenthal was being rested. Walden allowed one single and had one strikeout in the course of converting the save. Rosenthal had pitched in five of the previous seven games, so manager Mike Matheny predetermined that Rosenthal would get the night off. Walden has had closing experience before and had been pitching the eighth inning earlier this season, so it's no surprise that he got the nod.

Walden took the loss in Friday's game against the Reds, giving up a run on two walks in an inning pitched. Walden got in trouble when he walked Billy Hamilton, followed by an intentional walk to Joey Votto. Hamilton took third on a wild pitch before scoring on a sacrifice fly by Todd Frazier. It was Walden's first action since pitching a scoreless inning on Sunday.

Walden may get the first shot at closing for the Cardinals should Trevor Rosenthal be taken out of the role for some reason, the St. Louis Post-Dispatch reports. Matheny has suggested that Walden could be used in the ninth inning, a good indication that with a strong spring Walden will likely be the top setup man for the Cardinals, racking up holds and the occasional save this season. Walden sports a career 3.10 ERA and 10.8 K/9. He could be one of the more valuable non-closing relievers in 2015.

Walden agreed to a two-year deal with the Cardinals on Tuesday Walden's deal will keep him under contract through the 2016 season with a club option for 2017. He was added to the Cardinals' bullpen as part of a deal that also sent Jason Heyward to the Cardinals and Shelby Miller to the Braves. The 27-year-old reliever could be a candidate for a spot in the back end of the Cardinals' bullpen over the next couple of seasons.

Walden was traded to the Cardinals on Monday. Walden had his best full season in the majors last year, posting a 2.88 ERA and 1.20 WHIP with 62 strikeouts over 50 innings. He could find himself in the back end of the Cardinals bullpen in 2015 as well.

Jordan Walden picked up his third save of the season, pitching a scoreless ninth inning in Wednesday's win over the Mets. It was just a day of rest for Craig Kimbrel, who had pitched in three consecutive ballgames. Walden had no issues, retiring the Mets in 1-2-3 fashion with two strikeouts. The right-hander has been a solid contributor out of the 'pen for the Braves, now carrying a 2.70 ERA with a 1.20 WHIP and a 33/12 K/BB ratio in 23 1/3 innings.

Braves activated RHP Jordan Walden from the 15-day disabled list. Walden wound up missing a little over a month with a strained left hamstring. The right-handed setup man will be available out of the Braves' bullpen Tuesday night.
