Reds starting pitcher Michael Lorenzen (1-1) allowed one run on three hits in six innings Tuesday to defeat the Pirates and earn his first career victory.
The one run Lorenzen gave up came via a solo home run from Starling Marte.
Lorenzen made his major-league debut April 29 against the Brewers, allowing three runs on eight hits over five innings for a loss.
"I kind of collected myself and thought about what a young pitcher who had given up four home runs in his first two starts should do," Lorenzen said. ''I thought the answer was pound the strike zone, so that's what I tried to do."
Lorenzen's next start has not been announced as of Tuesday night.
