Braves pitching prospect Sean Gilmartin has been placed on Triple-A Gwinnett's disabled list due to shoulder tendinitis.
A 2011 first-round pick, Gilmartin has struggled this season with a 5.83 ERA and 47/30 K/BB ratio over 71 innings with Gwinnett. It's not clear how long he'll be sidelined.
Braves agreed to terms with 31st overall pick RHP Jason Hursh.
He got a $1.7 million signing bonus. Hursh was selected with the compensation pick that the Braves received for losing Michael Bourn to free agency. The 21-year-old sinkerballer posted a 2.79 ERA and 86/28 K/BB ratio in 106 1/3 innings this season for Oklahoma State.

Jason Heyward is not in Wednesday's lineup against the Mets.
Heyward played both games in Tuesday's doubleheader, so he'll get a breather. Jordan Schafer is making the start in right field Wednesday.
Paul Maholm allowed just two runs over seven innings but the Braves fell to the Mets on Tuesday.
Maholm was simply out-dueled by Mets right-hander Zack Wheeler, who was making his major league debut. The veteran lefty struck out seven New York batters and did not issue a walk, but he fell to 7-6. Maholm will get the Brewers in Milwaukee next time out.
Alex Wood left his start Tuesday against the Mets because of a split callous on his left index finger.
Wood allowed one earned run in three innings before exiting. It was only a spot start, and the young southpaw will likely be sent back to the Double-A level soon.
Alex Wood came out of his spot start Tuesday after allowing one run in three innings against the Mets.
The Braves never gave any official word, but it appeared that Wood was suffering from a finger blister. He impressed before departing, striking out five. The one run he allowed came on a misplay from third baseman Chris Johnson.
Braves recalled RHP Cory Rasmus from Triple-A Gwinnett.
He'll serve as the 26th man for Tuesday's doubleheader with the Mets. Rasmus has allowed five runs on five hits and three walks over 3 2/3 innings with the Braves this season.
