Wood will likely be back at the big league level by the time the Braves play a doubleheader against the Phillies on June 28. But the 23-year-old left-hander could return sooner if one of the current members of Atlanta's rotation suffers an injury or gets traded.
While with Gwinnett, Wood will have a chance to regain the endurance he has lost since last making a start on May 4. He has spent the past five weeks in Atlanta's bullpen. Before transitioning to a relief role, he allowed two earned runs or less in six of the seven starts he made.
Walden posted a 1.59 ERA, limited opponents to a .171 batting average and struck out 39 percent of the batters he faced in the 13 appearances he made before straining his left hamstring during that same May 4 game against the Giants.
