AUGUSTA, GA. — Bryan Mitchell tossed six innings of one-hit, shutout baseball to lead the Charleston RiverDogs to a 7-1 win over the Augusta GreenJackets in the final game of the RiverDogs’ South Atlantic League baseball season at Lake Olmstead Stadium on Monday afternoon.

The RiverDogs (73-63, 34-35 second half) end the season on a four-game winning streak and having won 10 of 11. The loss was the fourth straight for Augusta (69-73, 37-33).

The only hit allowed by Mitchell (9-11) was a seeing-eye single by Brett Krill to lead off the fourth inning. The right-hander did not walk a batter and struck out six. He retired the last nine men he faced.

Saxon Butler, Rob Refsnyder and Casey Stevenson all singled in runs in the first inning for a 3-0 lead for Charleston. Casey McGehee tacked on another run off Paul Davis (6-8) in the second with an RBI double.

In the fifth, singles by Dante Bichette Jr. and Stevenson sparked another rally. When Francisco Arcia singled to right, a throwing error by right fielder Devin Harris plated both runners to stretch the lead to 6-0. Stevenson’s single gave him a season-ending average of .300. Arcia drove in another run in the seventh on a groundout.

Philip Wetherell relieved Mitchell to begin the seventh and allowed a run on an RBI single by Elliot Blair, but that was all Augusta would get. Wetherell tossed a scoreless eighth and ninth for his seventh save.
