PITTSBURGH (AP) -- Josh Harrison hit an RBI triple and scored on Jose Tabata's tiebreaking single in the eighth inning, leading the Pittsburgh Pirates to a 2-1 victory over the Cincinnati Reds on Friday night.
Harrison had three hits in the Pirates' sixth win in eight games. Tabata, starting in right field for the injured Travis Snider, finished with two hits.
Pirates starter Edinson Volquez was working on a no-hitter before Devin Mesoraco's leadoff single in the seventh. He was charged with one run and three hits in 7 2-3 innings, running his unbeaten streak to seven starts.
Reds right-hander Mike Leake allowed six hits in seven innings in his second consecutive scoreless outing. He pitched 6 2-3 innings in a 1-0 victory over Atlanta last Saturday in his previous start.
Cincinnati put two runners on in the eighth, chasing Volquez from the game. Mesoraco then put the Reds in front with an RBI single against Tony Watson (10-1), but Brandon Phillips was thrown out at home to end the inning.
The Pirates' ERA is 2.15 over their last eight games.
Mesoraco had two of the Reds' four hits.
The Pirates' winning rally came against Jonathan Broxton (4-2).
Pinch-hitter Andrew Lambo, recalled from Triple-A Indianapolis before the game, singled off first baseman Todd Frazier's glove with one out. Then Harrison and Tabata followed with their big hits.
Reds: 1B Joey Votto experienced pain in the area of his troublesome left knee on Wednesday when he attempted to field ground balls for the first time since going on the disabled list July 6 with a distal quadriceps strain, manager Bryan Price said Friday. Votto won't be ready to play when he is eligible to come off the disabled list on Thursday, and the rest of the season is in doubt.
Pirates: 1B Pedro Alvarez (sprained left foot) sat out for a second game and Snider (left hamstring discomfort) was not in the lineup after leaving Wednesday's win over St. Louis. Both are day to day.
Reds: RHP Alfredo Simon (13-8, 3.26 ERA) will start Saturday in his first outing since breaking a five-game losing streak Sunday by beating Atlanta. Simon is 1-4 with a 4.74 ERA in eight starts in the second half after going 12-3 with a 2.70 ERA in 18 starts in the first half and being selected to his first All-Star game.
