Twins pitching prospect Kohl Stewart has been placed on Low-A Cedar Rapids' disabled list due to a right shoulder impingement.
Stewart dealt with a shoulder issue toward the end of last season and is having problems again, though the Twins at this point don't appear to be overly concerned. The No. 4 overall pick in last year's draft, Stewart owns a 2.42 ERA through 81 2/3 innings of work at the minor league level this season.
CBS Sports' Jon Heyman reports that the trade market for Jonathan Papelbon "seems light, if existent."
Papelbon has had a fine season, posting a 1.91 ERA while saving 24 games in 28 chances, but Heyman says "there seemingly isn't strong interest," especially with the Angels and Tigers having already acquired relievers. The Phillies are prepared to eat a portion of the $18 million guaranteed to Papelbon through the end of next season, but he also has a vesting option for 2016, something that Heyman notes "can be sticky for acquiring teams."
Wil Myers (wrist) hit off a tee on Friday.
It's the first time he's done so since fracturing his right wrist back in late May. Myers is expected back in mid-August if all goes well.
Marlins recalled C J.T. Realmuto from Triple-A New Orleans.
He'll serve as the Marlins' third catcher. Realmuto had four hits in 20 at-bats earlier this season for the big club.
Marlins optioned RHP Anthony DeSclafani to Triple-A New Orleans.
DeSclafani was up for nearly a week but didn't appear in a game. He'll return to a 2.82 ERA at Triple-A.
Astros transferred RHP Matt Albers from the 15-day disabled list to the 60-day disabled list.
The move clears space on the 40-man roster for Gregory Petit. Albers has been out since late April with right shoulder tendinitis and isn't close to returning.
Astros optioned RHP Anthony Bass to Triple-A Oklahoma City.
Bass allowed 10 earned runs over nine relief innings after being activated from the DL earlier this month. He should get another chance later this season.
Astros purchased the contract of INF Gregorio Petit from Triple-A Oklahoma City.
The Astros needed some infield depth with Marwin Gonzalez (hamstring) banged up. Petit hasn't played in the majors since 2009 but was batting .297/.340/.457 with 10 homers at Triple-A.
