CINCINNATI -- Jay Bruce hit a game-tying homer in the ninth, and four innings later Brandon Phillips won it with an RBI single, lifting the Cincinnati Reds to a 2-1 victory over the Pittsburgh Pirates in 13 innings on Wednesday night before 36,567 fans at Great American Ball Park.
In the 13th, Derrick Robinson reached on an infield single against Pirates right-hander Vin Mazzaro and advanced to third on Shin-Soo Choo's single. Joey Votto was intentionally walked to load the bases. Phillips' grounder up the middle snuck into center field for the game-winner.
Mazzaro (3-2) took the loss. Manny Parra (1-1) earned the victory for Cincinnati.
Pittsburgh (42-30) led 1-0 in the ninth when Bruce hit a game-tying solo homer off Jason Grilli.
Pirates starter Jeff Locke appeared in line for his seventh victory after allowing just four hits through seven innings. But Cincinnati (44-29) rallied for the win.
The Reds' scoreless streak had reached 17 1/3 innings when Bruce's homer on Grilli's first pitch sailed 417 feet to right field, tying the score 1-1. It was Grilli's first blown save in 25 chances.
Ironically, it was Bruce who drove in the Reds' last run: a solo home run in the eighth inning of Monday's series opener.
Reds starter Bronson Arroyo allowed just one unearned run (on his error) through seven innings. He gave up six hits, walked three and struck out three.
Despite having 101 pitches after six innings, Arroyo came back out for the seventh. Bruce picked him up with a leaping grab of Lawrence McCutchen's drive near the top of the right-field wall.
Pittsburgh had the bases loaded with one out in the sixth but failed to score.
Locke retired eight in a row before Todd Frazier's double in the seventh. Frazier was left stranded at third extending Locke's scoreless innings streak to 14.
Reds left-hander Tony Cingrani struck out all three batters he faced in the eighth, and Alfredo Simon pitched a scoreless ninth, to keep it a one-run and give Cincinnati a chance to rally.
The Reds had six base runners and three reached second base against Locke through three innings, but none scored.
Zack Cozart, attempting to score from first base on Ryan Hanigan's double, was thrown out at home on a relay throw from second baseman Neil Walker to end the inning.
Marte tripled with two out in the third, then scored the Pirates' first run when Russell Martin reached on an infield single that caromed off Arroyo's glove for an error.
The Pirates had two runners on in the fifth, but Arroyo picked off Garrett Jones at second base to end the inning.
NOTES: Robinson batted leadoff in place of Choo, who hit second against the left-handed Locke. Choo was batting .169 against left-handers, while Robinson was hitting .302. ... Marte's triple in the third inning was his fifth this season, tied for third-most in the National League. ... Arroyo issued two walks in the fourth inning after having two walks combined in his previous 24 2/3 innings. ... Tuesday's shutout was the 12th this season logged by Pirates pitchers, the most in the majors. They needed only 71 games to do it, the fewest by a Pittsburgh staff since the 1906 team also had 12 in the first 71 games and the fewest in the majors since the Mets had 13 in their first 71 games of the 1988 season, according to Elias Sports Bureau.
