The Pirates beat the Cincinnati Reds, 4-2, in the first game of a doubleheader but had to settle for a second consecutive series split after losing the nightcap, 5-1, Thursday at Great American Ball Park.
It was a big bounce-back game for rookie right-hander Roansy Contreras.
Contreras (3-2) earned the win after completing his first career six-inning start and allowing one run on four hits and one walk while striking out seven on 90 pitches.
After the game, Contreras was optioned to Triple-A Indianapolis as the Pirates recalled left-hander Eric Stout. Contreras will remain with the club on the taxi squad.
The Pirates added right-hander Bryse Wilson as their 27th man for the doubleheader to start the second game. Wilson was named player of the month for Triple-A Indianapolis.
The Pirates are in Milwaukee tonight at 8:10
