FOX Sports' Ken Rosenthal reports that the Nationals have inquired on Mark Melancon.
Rosenthal adds that there are "multiple teams" pursuing the closer. The Pirates are in the thick of the Wild Card hunt, but it appears they still might consider trading Melancon, who is an impending free agent. Rosenthal notes that the Nats have also inquired on Wade Davis, as they seem likely to acquire a reliever this weekend with Jonathan Papelbon struggling.
Nelson Cruz (foot) is back in the Mariners' lineup Friday.
Cruz missed a game after fouling a ball off his foot, but he's fine. He's in right field and batting cleanup against Jon Lester and the Cubs.
Brayan Peña (knee) has resumed taking batting practice and catching bullpen sessions.
Cardinals manager Mike Matheny indicated that Peña has lost roughly 15 pounds since being placed on the disabled list a few weeks ago with soreness in his surgically-repaired left knee. However, it's unclear when he might be ready for a rehab assignment.
Jhonny Peralta (thumb) will join the Cardinals in Miami as soon as Friday to resume on-field baseball activities.
Peralta would prefer to avoid a rehab assignment as he works his way back from soreness in his surgically-repaired left thumb. He's eligible for activation early next week, although it's unclear whether he might possibly be ready by that time.
Brandon Moss (ankle) went hitless in three at-bats in his first rehab game with Double-A Springfield on Thursday.
He'll remain with Springfield through the weekend and is on track to be activated from the disabled list early next week if all goes well. Moss has missed most of July with a left ankle sprain.
Cubs activated INF/OF Chris Coghlan from the 15-day disabled list.
Coghlan has been out nearly all month with a right rib cage injury. He's in left field and batting leadoff Friday.
Cubs optioned INF Tommy La Stella to Triple-A Iowa.
La Stella has batted .295/.388/.457 this season, but with Chris Coghlan (rib cage) back from the disabled list there weren't going to be many at-bats available for him. He'll be back eventually.
Jeff Passan of Yahoo Sports reports that Matt Moore is "emerging as the likeliest trade candidate" from the Rays' rotation.
The Rays are listening on Jake Odorizzi, Drew Smyly and even Chris Archer, but Moore has always seemed to be the most likely to be shipped elsewhere. Swingman Erasmo Ramirez could also be traded. Moore has been frustratingly inconsistent in his time in Tampa but holds a 2.39 ERA over his last nine starts and the Rays have club options on him through 2019 totaling a reasonable $26.5 million. The Rangers and Pirates are among the teams poking around.
