PITTSBURGH — Marcell Ozuna knew he found something in the first inning. He battled for eight pitches before getting ahold of a fastball, only to see it fly right to Pirates left fielder Bryan Reynolds.
The next time up, Ozuna put it all together. He hit a three-run homer to break out of his slump, and Adam Wainwright pitched seven strong innings, to help the St. Louis Cardinals extend their lead atop the NL Central with a 10-1 win over Pittsburgh on Saturday night.
"I was ready to swing," Ozuna said. "I was ready to battle. (We had runners on) first and second. (Paul Goldschmidt) had flied out. Let me go after one. A couple games, I don't drive in any runs. That one swing in the first at-bat, I said, 'I think I got it.'"
The Cardinals are 3 ½ games ahead of the Cubs for first in the Central with Chicago's 3-2 loss to Milwaukee.
After Dexter Fowler opened the scoring with an RBI single earlier in the third inning, Ozuna connected against Steven Brault (4-4) for his 26th home run of the season and a 4-0 lead. The cleanup hitter also walked twice after having two hits in his previous 35 at-bats.
Wainwright (11-9) helped himself, and the Cardinals wearing their baby blue uniforms, with a double and single while lasting seven innings for the second straight start. He gave up one run and six hits.
"Today was about bucking the trend and personal challenges," Wainwright said. "They say the Cardinals don't win in the baby blues. They say Waino doesn't pitch well in Pittsburgh. So perfect. Those were the two thoughts I went into the game with trying to prove that wrong."
Starling Marte drove in the Pirates' run with a single in the third. He had three RBIs and four hits, including a first-inning triple Saturday, in seven at-bats in two games since missing the previous two with a leg injury.
Tommy Edman and Harrison Bader chased Brault with a pair of RBI singles that extended the lead to 6-1 in the sixth. Brault allowed six runs and six hits in 5 1/3 innings with two walks, a balk, a wild pitch and a hit batter.
"Below average command today was his biggest problem," Pirates manager Clint Hurdle said. "He had eight three-ball counts on the day. ... Not a lot of swing and miss. He's had more in the past with two walks and two strikeouts. He went out there fighting. He just wasn't sharp."
Brault hadn't given up more than four runs in 15 appearances — 13 starts — since May 12, when St. Louis also tagged him for six in 3 2/3 innings before losing 10-6.
"The way I was taught is that if you have 30 starts a year, you're going to have four starts where you feel incredible, four starts where you feel terrible, and then 22 starts where you'll be somewhere in the middle," Brault said. "Tonight was somewhere in the middle, but near the bad side. Three-run home runs are day-killers, so keep the ball out of the stands and it'll be a different ballgame."
Paul DeJong tacked on two more runs with a double off Clay Holmes, making it 8-1 in the seventh. Bader hit an RBI double in the ninth before Andrew Knizner scored on a groundball to cap it.
"We show up ready to go every night," Cardinals manager Mike Shildt said. "Get better as the series goes. ... Guys just had tough at-bats, and just added on."
