The host Pittsburgh Pirates scored 15 runs in the first four innings and took advantage of record wildness by the Cincinnati Reds to roll to a 17-7 victory on Saturday.

Rookie Konnor Griffin doubled, tripled and went 4-for-5 while driving in two, while Ryan O'Hearn doubled and drove in three as the top eight hitters in the Pirates lineup each had at least one hit while seven batters had at least two hits.

Pittsburgh also drew seven consecutive walks in the second inning -- tying a major league record set in 1909 and equaled in 1983. The Pirates scored five runs in the second without a hit, becoming the first team to accomplish the feat since 1994.

Right-hander Carmen Mlodzinski (2-2) was the beneficiary of the offensive outburst. He struck out a career-high 10 while scattering eight hits, two walks and five runs over 5 2/3 innings.

Will Benson and JJ Bleday homered and Nathaniel Lowe drove in three runs for the Reds, who trailed 15-3 after four innings. Cincinnati starter Rhett Lowder (3-2) surrendered eight runs, five hits and four walks before being removed with one out in the second.

Since losing 2-0 to Cincinnati in their first meeting on March 30, Pittsburgh has won the last four by a combined 42-14 score.

For a second straight day, the game was played in raw conditions, with a game-time temperature of 43 degrees.

Lowder appeared miserable in the cold and struggled badly early. He was unable to find his rhythm or command while allowing four runs before there were two outs in the first inning. The five runs allowed in the first were a career high for the right-hander.

Lowder labored through 30 pitches in the first as O'Hearn, Marcell Ozuna and Griffin each doubled in the five-run outburst. Lowder then walked the bases loaded in the second before being pulled.

Reliever Connor Phillips came in and walked all four Pirates he faced to force in four runs. He left after throwing just five of his 21 pitches for strikes.

The last time seven straight walks were issued in a Major League game came on May 25, 1983, when three Pirates pitchers walked seven in a row at Atlanta in a 6-0 Braves win.

The five runs without a hit in the second happened for the first time since April 27, 1994, when the Seattle Mariners allowed five runs to the New York Yankees in the top of the third inning.

With the score 15-6, Pittsburgh reliever Chris Devenski was ejected for throwing inside near the ribcage of Sal Stewart to open the seventh. Stewart took exception and stared out at the mound. But the encounter did not escalate as umpires intervened.
