Capuana initially felt the pain in his elbow during is May 20 outing, and felt it again after pitching against the Braves on Wednesday. It is a bit troublesome to hear that the left-hander experienced the same sensation during his second Tommy John recovery, although he did say no tests thus far have pointed toward ligament damage. He'll likely take some anti-inflammatories in the coming days and possibly even undergo an MRI when the club returns to Milwaukee, but it seems that Capuana has avoided a major injury this time around.
Riefenhauser has some major league experience, but that's about all he has going for him this season. With the I-Cubs, the 26-year-old is sporting a 7.30 ERA through 12.1 innings pitched, leading the Cubs to boot him from the 40-man roster. After no teams claimed him, the left-hander will likely act as organizational pitching depth going forward.
The Braves needed reinforcements for their bullpen after Casey Kelly, who was previously scheduled to start Saturday, was forced to fire 77 pitches in relief during Wednesday's 13-inning marathon match with the Brewers. Withrow has been lights out for the Triple-A squad, not allowing a run and striking out 10 batters in 8.1 innings out of the bullpen, making him a clear callup candidate. He'll likely work in lower-leverage situations until the Braves are in need of a fifth starter again. To make room for him on the roster, starting pitcher Casey Kelly was optioned to Triple-A.
Goforth has been putting up solid numbers out of the Sky Sox bullpen, making him a clear candidate for promotion when Chris Capuana (elbow) was placed on the disabled list. Goforth will likely slot into a middle relief role and mainly pitch in lower-leverage situations, especially if he can't improve his 7.20 major league ERA he holds from his first stint with the parent club.
It's unclear when the ailment cropped up, as he was able to finish the lone inning he threw in during Wednesday's contest. The left-hander has undergone two Tommy John surgeries during his career, so naturally there is some concern over this ailment, but it's currently unclear what the problem actually is this time around. A clearer timetable should become available once the severity of this injury is determined. Right-hander David Goforth was recalled from Triple-A Colorado Springs to take his place in the Brewers bullpen.
Morris was placed on the disabled list earlier in the day Thursday, and although his back ailment could keep him on the shelf for a while, surgery would probably force him to wait to return until 2017. The 29-year-old hasn't made a decision yet, but his status for the rest of the season will likely be dependent on if he has surgery or not, a choice that could be made sometime within the next week.
Thornton was roughed up a bit in his most recent rehab appearance, giving up two runs on two hits in an inning with High-A Lake Elsinore, but his Achilles is feeling much better and is even holding up through PFP during games. No official move has been made yet, but it seems as if the veteran left-hander is very close to making his debut in the Padres bullpen.
Avilan pitched well in his lone appearance since being called up Monday, but it seems the Dodgers are clearing a path for when they call up top prospect Julio Urias from Triple-A. Avilan will likely continue to shuttle between Triple-A and the majors throughout the season, so he could be back in the major league bullpen fairly soon if Los Angeles needs more pitching help at the big league level.
Osich has now given up three runs over his last three appearances, seeing his ERA rise from 1.84 to 3.31 over that span. His combination of sub-par control (3.31 BB/9) and susceptibility to the long ball (1.65 HR/9) make him a risky middle-relief option.
Wittgren will replace reliever Bryan Morris in the bullpen while he is on the disabled list with a herniated disc in his lower back. Wittgren posted a 3.18 ERA and 1.59 WHIP in 5.2 innings during his two stints in the majors this season.
