The Power's recent run of big offensive production and overall efficiency had produced a four-game winning streak, as well as expectations of more to come.
Not that any of those things mattered to the Asheville Tourists, most notably catcher Will Swanner and pitcher Vianney Mayo.
Swanner contributed two home runs and seven RBIs and Mayo pitched a complete-game shutout - a minor league feat on the verge of extinction - as the Tourists routed the Power 16-0 Monday night at Appalachian Power Park. A paid crowd of 1,400 attended.
In an era when strict pitch counts often force minor leaguers from the mound in the sixth inning or earlier, Mayo economized by throwing first-pitch strikes, not walking a batter and allowing just three hits. He struck out nine.
But with two outs in the ninth, as his pitch count moved past 90, he faced the Power's Josh Bell and stood on the brink of removal.
"That was his last hitter. He was done,'' said Asheville manager Joe Mikulik. "We were going to stall and get another guy ready and take him out. I would have liked to leave him in, but you have to take him out.''
Mayo, however, fanned Bell for the South Atlantic League's first complete game of the season.
"He just got ahead of the hitters and kept the ball down with plus command,'' said Mikulik. "Then he showed a breaking ball when he had to. He was very, very impressive. It was good to see.''
Swanner, who entered the game as a .227 hitter with no homers or RBIs, hit a grand slam to left-center to cap a seven-run third inning and added a two-run blast in the seventh. He also doubled and scored in a four-run fifth inning.
His three hits lifted his average to .308 in what has been an impressive offensive start for the Tourists (8-4), a Rockies team that started the night with a league-leading .306 team batting average.
