Since joining the Pirates last year, Nova now has five complete games in his 16 starts. He needed just 95 pitches to get through nine innings.
The Marlins, conversely, had a stretch of four straight walks in the sixth inning that forced in two runs. Dan Straily was lifted after 5 1/3 innings after allowing four hits with five strikeouts. But he was hurt by three walks.
Jordy Mercer, who hit a first-inning home run in Friday's 12-2 win, delivered a two-out RBI single that put the Pirates ahead in the second inning.
