Javier Baez tagged Sims for a solo home run in the bottom half of the inning but Rio Ruiz answered with a solo shot of his own in the fourth to keep it a one run game at 5-4.
However, the wheels came off for the Braves in the bottom half of the frame. A lead off walk to Lester got things started. Jon Jay followed with a single to put runners at first and second with no one out.
Sims was replaced by Ian Krol who was seeing his first action since being activated from the disabled list on Friday.

The Braves weren’t finished yet offensively scoring three times in the seventh with the big blow coming on a double by Nick Markakis that plated both Albies and Freeman. Kurt Suzuki followed with a run scoring single to cut the deficit to 11-7. Dansby Swanson then doubled to put runners at second and third but forgot how many outs there were as he was doubled off on a line drive to second by Ruiz to end the threat.
