PITTSBURGH -- Chris Heisey homered twice while Johnny Cueto limited the Pittsburgh Pirates to two runs in eight innings as the Cincinnati Reds avoided a sweep with a 3-2 victory on Sunday at PNC Park.
Cueto (16-8) is now tied for the league lead in victories after working eight innings and allowing two runs, nine hits, one walk and striking out six.
Heisey hit his second home run of the afternoon off Pittsburgh right-hander Jared Hughes (6-5) with one out in the ninth.
Pittsburgh left-hander Francisco Liriano threw a season-high 111 pitches in seven innings of work. He allowed two runs on five hits, three walks and struck out five batters.
Liriano needed only 43 pitches to work through an efficient first four innings as the Reds did not record a hit off him until first baseman Todd Frazier singled with two outs in the fourth.
Cincinnati left-hander Aroldis Chapman worked the ninth for his 29th save of the year.
Pittsburgh third baseman Josh Harrison barely cleared the wall in left field with a drive on the first pitch he saw from Cueto for a 1-0 Pirates lead in the first. Harrison's 13th home run of the season followed Liriano's first inning in which he struck out the side.
Shortstop Jordy Mercer doubled the lead in the next inning when he homered to the bleachers in left field off a 2-2 slider Cueto hung over the plate.
The Pirates had a chance to add another run in the third after right fielder Andrew Lambo doubled to shallow left field. Cueto struck out center fielder Andrew McCutchen and induced a foul pop-up from second baseman Neil Walker to end the threat.
Cincinnati tied the game in the fifth on Heisey's two-run home run after Liriano walked left fielder Ryan Ludwick leading off the frame. The Reds moved men to second and third but stranded them as second baseman Brandon Phillips grounded out.
