Telis, 24, was acquired from the Rangers before the non-waiver trade deadline and batted .105/.150/.105 with a pair of RBIs through 11 major league contests this season. Manager Dan Jennings said the club plans to recall Telis when rosters expand in September.
"We needed to have some innings covered," Jennings said. "We've taxed our bullpen pretty hard the last three or four days. We think it will be good for him to go down and get some regular playing time and bring him back when the rosters expand in September."
In the corresponding move, the Marlins selected the contract of Scott McGough. McGough posted a 2.25 ERA in Triple-A after being promoted from Double-A Jacksonville. He underwent Tommy John surgery last June and was acquired in the Hanley Ramirez deal with the Dodgers in 2012.
Other Marlins notes:
-- Miami is hoping Giancarlo Stanton can return to the starting lineup in the coming weeks. Stanton said he has hit off the machine "without pain" over the last few days.
Stanton added while he does still have pain in his hand, it continues to get stronger: "We're getting there. Slowly, but we're getting there. It's just wrist weakness. It's not the actual surgical part. It's the weakness in my wrist turning over."
Jennings said there is no timetable because "we want him to be comfortable and we want him to be one hundred percent."
-- David Phelps, who will miss the remainder of the season with a stress fracture of the radius bone in his forearm, said he does not expect the injury to linger into next year: "We thought it was something like tendinitis. I wanted to give myself a chance to pitch through it and hopefully it would heal and get better, but it didn't work out that way."
Phelps posted a 4.50 ERA over 112.0 innings with the Marlins this season.
--Christian Yelich, who was placed on the disabled list with a right knee contusion last week, said the knee is "not where it needs to be yet."
Yelich took batting practice on Thursday and Jennings said he just has to "get comfortable running on it." Over 92 games, Yelich is batting .275/.343/.376 to complement six home runs and 29 RBIs.
-- Carter Capps threw a bullpen session on Thursday and the Marlins plan on sending him on a rehab assignment before he returns, Jennings said.
-- Jarred Cosart is no longer suffering from symptoms of vertigo and plans on throwing in a regular game on Monday, Jennings added.
