Nolan Arenado hit a go-ahead two-run single in the seventh inning and finished with three RBIs, helping the St. Louis Cardinals stretch their winning streak to seven games with a 6-4 victory over the Arizona Diamondbacks on Sunday.

Trailing 4-3, the Cardinals loaded the bases in the seventh after pinch-hitter Albert Pujols singled off Joe Mantiply (1-4) and Kevin Ginkel hit Paul Goldschmidt with a pitch. Arenado, who had a run-scoring single in the first inning, fell behind 1-2 against Ginkel, but lined a single to right-center to put St. Louis up 5-4.

Jake Woodford (2-0) allowed a hit in 1 1/3 innings and Giovanny Gallegos worked a perfect ninth for his 12th save to complete the NL Central-leading Cardinals' seventh sweep this season.

Lars Nootbaar hit his first career leadoff homer and Tommy Edman added a run-scoring single in the eighth inning for St. Louis' 16th win in 19 games.

Cardinals Manager Oliver Marmol was ejected in the third inning after saying something to plate umpire C.B. Buckner about a called strike.

With one out in the inning, Buckner called a strike on a pitch to Arenado that appeared to be well inside. Buckner didn't hesitate in tossing Marmol, ripping off his mask to toss him out of the game.

Marmol came out of the dugout and got in Buckner's face while yelling before being pushed back by third base umpire Jeff Nelson.

Jose Quintana had been superb since an Aug. 1 trade from Pittsburgh, allowing three earned runs in 17 innings over three starts.

The left-hander had his first clunker against Arizona.

Struggling with his command, allowed four runs - two earned - on seven hits and walked three in 2 2/3 innings.

Jordan Montgomery (6-3, 3.29 ERA) is 3-0 with a 0.54 ERA since being traded from the Yankees headed into Monday's start against the Cubs.
