Catcher Evan Gattis was expected to have a fourth consecutive workout day Sunday at Single-A Rome, where he’s been taking batting practice, running and throwing in preparation for a rehab assignment that could begin as soon as Tuesday after an off day in Rome’s schedule Monday. Gattis has been on the 15-day disabled list since June 28 recovering from a bulging disk in his upper back, and will be eligible to come off at any time after the All-Star break. The Braves will likely have him play at least a few rehab games before activating him. The Braves haven’t given a specific target date for Gattis’ return or said when his first rehab game will be, but Rome has a three-game series against Greenville beginning Tuesday. Braves workout: Gonzalez will have an optional workout for the Braves on Thursday at Turner Field. He said he doesn’t want the team’s All-Stars – Freddie Freeman, Craig Kimbrel, Julio Teheran – to attend the workout because he hopes they’ll take a day to relax after returning from the All-Star festivities in Minneapolis.
