The Cougars (11-3, 3-2) won their fourth game in a row and second straight in conference play. Furman fell to 8-7 and 0-2 in SoCon play.
Powell (3-1) went for his longest outing of the season, pitching eight innings, allowing just three hits and tying his career high with eight strikeouts. Powell set down the last 13 Furman batters in a row that he faced.
Senior David Peterson came into the ninth inning in a non-save situation, but allowed three runs to open the door for Furman. With the winning run on second base, Owings came in and struck out Hunter Burton on a called third strike for his first save of the season.
Furman threatened Powell in the third inning after an infield single and a double to right put runners at second and third with none out. Powell recorded a strikeout on the next batter, but leadoff batter Will Owens walked to load the bases. Will Miller hit a fly ball to center that was gloved by Marty Gantt and it appeared that Harrison Farmer had scored on the sacrifice, but CofC catcher Ryan Welke appealed to third and Farmer was called out for leaving early on the play.
Murray broke the tie in the top of the fourth inning with a solo home run to right field. The bomb was the second this week for Murray and his third this season.
The Cougars added another run in the top of the sixth with a single up the middle from Jackson to score Brandon Glazer from second base for Glazer's first run of the year.
Senior Rob Harding recorded his team-best 15th RBI of the season in the seventh inning with a single that scored Heidt from third base. Heidt reached on a single and advanced to third on a failed pickoff throw that went wide.
The Cougars added a run in the top of the ninth inning after Martin, Heidt and Harding loaded the bases with a hit-by-pitch, single and an intentional walk. Bradley Goodson drew another walk to score Martin and make the score 4-0, a run that would become all-important after Furman's three-run ninth inning.
The Cougars will go for the sweep of the three-game series on Sunday at 1 p.m. at Furman's Latham Stadium.
