Randall Delgado was credited with his fifth straight loss and was charged with four runs on seven hits in 5 1/3 innings. He had only given up one run going into the sixth, but he walked Brandon Phillips on a full count and a check swing to start the inning, and everything went downhill.
Delgado would retire Jay Bruce on a line out before allowing a single to Chris Heisey and a walk to Todd Frazier to load the bases, resulting in a hook from Fredi Gonzalez for Kris Medlen. On a 1-1 count, Medlen ran a two-seam fastball too far inside to Devin Mesoraco, who hit his first career grand slam to give the Reds the lead.
On the way to their sixth straight game of scoring fewer than four runs, Atlanta was once again without vital pieces of the lineup, as Chipper Jones and Brian McCann were once again out with their ailments, and Freddie Freeman was out of the lineup with his continuing dry eye problems.
The sweep is the first time the Reds have swept the Braves in Cincinnati since 1990.
The Braves must now turn their attention to their three-game home series with the Washington Nationals starting Friday. The Nationals, who rank first in starters ERA and total ERA, lead the Braves by a game in the National League East standings.
Tim Hudson (3-1) will look to right the ship and continue his hot streak against a slumping Ross Detwiler (3-3) Friday at 7:35.Tags: Atlanta, Atlanta Braves, Cincinnati Reds, Juan Francisco, Michael Bourn, MLB, Randall Delgado
