Gabe Medina, Ferdin Tejeda and Jonathan Hovis combined for the 1-hitter:
The 23-year-old right-hander fanned six batters and set down the final seven batters he faced during a season-high six innings.
"[Medina] was pretty dominant from the start. He allowed just that one hit," Hovis said. "The guys behind us made some good plays too. [First baseman Kevin Smith] made a great play, taking away a sure hit, and so did [third baseman Mitch] Hilligoss."
Tejeda tossed two perfect innings and Hovis worked a 1-2-3 ninth to preserve the shutout and notch his South Atlantic League-best 19th save as the final 16 Columbus batters went down in order.
"We have had several games without walking a batter, and whenever that happens [the pitchers] get to take BP," said Hovis, who hasn't got caught up in being the league's active saves leader.
"It's definitely good to have the lead, but you can't really think too much about stats," he said. "I'm going to pitch the same way always."
It was the second consecutive game that the RiverDogs flirted with a no-hitter. Eric Hacker took one into the seventh inning Wednesday.
Friday night, the Catfish avoided the sweep, winning the 3rd and final game of the series, 3-1, behind the pitching of Woods Fines:
Fines (6-5) gave up one run on six hits and a walk, striking out one. Ryan Owen fanned two and pitched around a hit and a walk over 2 1/3 innings before Brian Baker got the final two outs for his sixth save.
Quinn Stewart belted a solo homer, his 13th, in the sixth for the Catfish (12-9). Ryan Royster's bases-loaded walk snapped a 1-1 tie in the seventh and John Matulia added an insurance run in the eighth with an RBI infield single.
Desmond Jennings went 3-for-4 with a walk and his 39th stolen base.
The Catfish return home tonight, opening a 7-game home stand, beginning with 3 against Rome.
