Augusta's offense over the first six games of the homestand had been dismal, but three home runs in the past two nights sparked two wins against one of the best teams in the South Atlantic League.
"If I could figure this thing out, I'd be a millionaire and a big league manager," Machemer said. "We had a team meeting and talked about confidence. It's not rocket science; just go up there and see ball, hit ball."
The strategy worked Monday night. Every GreenJackets starter recorded at least one hit, and three Augusta pitchers combined for a shutout.
Chris Dominguez and Ryan Cavan led the offensive surge with a pair of three-run homers. Dominguez hit his team-leading 17th home run of the season in the third inning.
Cavan's 12th homer of the year capped a five-run fifth to break open the game.
"We know we're capable of hitting," Dominguez said. "It just happened tonight."
Kelvin Marte made his first start for Augusta and kept Asheville scoreless through 3 2/3 innings. Wilmin Rodriguez (4-3) got the GreenJackets through the fifth, and Jeremy Toole took care of the final four innings for his first save of the season.
The GreenJackets tagged Asheville starter Juan Gonzalez (3-6) for eight runs on 10 hits in 4 2/3 innings to claim their largest margin of victory since beating Hagerstown by 10 on May 8.
Machemer shuffled the starting lineup out of necessity. Luke Anders, Hector Sanchez and Daniel Cook were injured, leaving the team without a position player on the bench.
Machemer said reserve Skyler Stromsmoe is expected to join the team from Double-A Richmond today to help fill the void. Cook will go on the disabled list.
