CINCINNATI -- Third baseman Pedro Alvarez homered and drove in five runs, and starter Brandon Cumpton allowed one earned run over five innings to lift the Pittsburgh Pirates to a 5-3 victory over the Cincinnati Reds on Thursday afternoon, securing a split of the four-game series at Great American Ball Park.
Alvarez hit a solo home run off Reds starter Homer Bailey to tie the game in the sixth in front of a sold out crowd of 40,929. Then, with the bases loaded in the seventh, he broke the game open with a bases-clearing double off lefty Tony Cingrani to put Pittsburgh (43-30) ahead for good.
Jay Bruce hit his 15th home run for Cincinnati (44-30), which has lost six of 10 games this season against Pittsburgh.
Alfredo Simon (5-3) took the loss. Bryan Morris (4-2) got the victory.
With closer Jason Grilli unavailable after pitching in Wednesday night's 13-inning loss, Tony Watson earned his second save of the season with two perfect innings.
The Pirates (43-30) left 14 runners on base in Wednesday's marathon, and it looked like their struggles would continue Thursday when Starling Marte opened the game with a double, but was stranded. Alvarez would later provide all the clutch hitting the Bucs would need.
Cincinnati scored first in the opening inning when Shin-Soo Choo reached on a throwing error by Alvarez, stole second and scored on Joey Votto's hit. The Pirates tied the score in the third on Garrett Jones' two-out RBI.
Bruce put the Reds back on top in the fourth with a 415-foot homer to center on a 3-2 pitch from Cumpton, making the score 2-1.
Cumpton allowed two runs -- one earned -- on five hits in five innings. He walked one and struck out three.
Alvarez answered Bruce with his 16th homer, a solo shot off Bailey leading off the sixth to tie the score at 2. Bailey allowed two runs on six hits with no walks and eight strikeouts in six innings.
