Right-handers Addison Reed, Fernando Rodney, John Axford, Edward Mujica and David Aardsma have all cleared revocable trade waivers, reports Joel Sherman of the New York Post, making them eligible to be dealt to any club.

Of the listed group, only the veteran Aardsma has even posted a sub-4.00 ERA this season, as the 33-year-old has a 3.95 ERA with 10.2 K/9 and 4.6 BB/9 in 27 1/3 innings with the Braves. He’s generating grounders at just a 29.9 percent clip though and has had some home run issues to go along with his questionable control. Aardsma inked a minor league deal with the Braves, so his salary for the remainder of the season is light in comparison to the peers with whom he’s listed.

Reed, 26, was an up-and-coming closer not long ago was viewed in a strong enough light for the D-Backs to surrender one of their top prospects (Matt Davidson) for him in the 2013-14 offseason. His first season with the Diamondbacks resulted in a 4.25 ERA, however, and he’s up to 4.46 this season. Reed lost his job to Brad Ziegler earlier in the year and has been demoted to Triple-A this season.

Since returning, Reed has yielded just one run on nine hits and a walk with eight strikeouts in 10 innings, so things do look considerably brighter of late. However, Reed is also earning $4.875MM this season, and he’s still owed about $1.33MM of that sum through season’s end. He’s controllable through the 2017 season but is a definite non-tender candidate following the season, as he’ll top $5MM via arbitration despite his 2015 struggles.

The 38-year-old Rodney is perhaps the least surprising name on Sherman’s list. In 50 innings this season, he’s posted a 5.05 ERA with diminished strikeout (7.6 K/9) and walk (4.1 BB/9) rates to go along with a career-worst 1.44 HR/9 rate. Rodney’s fastball is averaging 94.9 mph, so he still has plenty of heat, but the results haven’t been there in 2015, and he’s owed $1.91MM of his $7MM salary through season’s end.

Axford, 32, has seen his share of struggles as well in his first year with the Rockies. Axford began the year in dominant fashion, yielding just one run in 19 innings and usurping LaTroy Hawkins as the Colorado closer. However, in the 19 2/3 innings that have followed that initial stretch, he’s been tagged for 19 runs on a dismal 29 hits and 15 walks. Teams in search of relief help may have some degree of hope that Coors Field has contributed to his poor results of late; Axford does have a 5.32 ERA in Denver versus a 3.78 ERA on the road. But, walks are walks in any park, and Axford has issued 10 free passes in 16 2/3 innings on the road.

Mujica has already been designated for assignment once this season (by the Red Sox), and his numbers have only worsened following a trade to the Athletics. The 31-year-old is still showing excellent control (1.3 BB/9 rate), but he’s averaging just six strikeouts per nine innings and has been entirely too hittable. Opponents are batting .309/.336/.525 against Mujica in 2015, and the result has been an unsightly 5.25 ERA. Even if he weren’t owed $1.3MM through the end of the season, he’d be a tough sell as a bullpen upgrade for a team seeking relief help.
