AUGUSTA -- Augusta's Chris Dominguez drilled a walk-off solo home run in the bottom of the 15th inning to lead the GreenJackets to a 5-4 win over Charleston on Tuesday night, snapping the RiverDogs' six-game winning streak.

After a scoreless 14th from Ben Watkins (3-3), the right-hander was sent out for the 15th and gave up Dominguez's homer. It was the second time this season that Dominguez has hit a walkoff home run against Watkins, nailing a three-run homer in a 5-2, 11-inning triumph on April 19.

Wilmin Rodriguez (3-3), who is scheduled to start for Augusta (19-18, 60-47) on Thursday, earned his second win against the RiverDogs (20-18, 51-56) this season.

Charleston registered three straight hits with one out in the first against Andy Reichard to snare a 3-0 lead. Luke Murton's RBI double and Neil Medchill's two-run double accounted for the early offense.
