St. Louis Cardinals manager Mike Shildt changed his lineup after arriving at Nationals Park, dropping catcher Yadier Molina from second to sixth.
Molina responded with a grand slam, Marcell Ozuna homered twice and the St. Louis Cardinals beat the Washington Nationals 11-8 on Tuesday night.
Molina's sixth career grand slam provided a cushion for St. Louis, making it 11-5 with two outs in the ninth.
"It did work out. We were happy with it," Shildt said. "Just thinking about different ways as the lineup has looked the last couple of days, maybe lengthening it out, spreading some things out a little bit."
The Cardinals (77-62), who occupy the second NL wild card spot, hit five homers overall as they stopped a three-game skid.
Right fielder Yairo Munoz robbed Ryan Zimmerman of a three-run homer in the bottom of the ninth, reaching over the fence and pulling it back into the field of play for a two-run double.
Tyson Ross (8-9) pitched 1 1/3 innings for the win and Jordan Hicks got the final out for his sixth save in 11 chances.
Ozuna and Paul DeJong homered leading off the sixth inning to break a 4-4 tie, and one out later, Patrick Wisdom went deep to make it 7-4.
Making his second major league appearance, reliever Austen Williams (0-1) gave up all three of those homers. He allowed none in 68 innings this season in Double-A and Triple-A.
"There's just things that I might be able to do in the minor leagues that I can't here," Williams said. "I need to trust my breaking ball more and just try and be better with two strikes if I want to throw a fastball."
The 4-hour, 10-minute game included 16 walks and 20 strikeouts. St. Louis pitchers walked 11.
"The walks are concerning. That's 11, 10 yesterday and eight the day before," Shildt said. "It's actually kind of impressive. ... We've had a real opportunity to win all the last three games."
Wilmer Difo homered and Bryce Harper had a double and three walks in five plate appearances for the Nationals, who fell one game below .500 after relievers Williams and Solis combined to give up seven runs.
"They are going to get an opportunity to pitch, so they got to realize if they want to pitch here they got to get outs," manager Dave Martinez said. "I can't keep using the same guys every single day."
Ozuna led off the second with his 17th homer, and Matt Carpenter capped the inning with a two-run single that made it 4-0.
Washington rallied in the fifth when Zimmerman led off with a grounder to second that second baseman Munoz misplayed for an error. Harper later drove in two with his bases-loaded double, and Trea Turner and Juan Soto drew bases-loaded walks.
Erick Fedde allowed four runs in five innings. John Gant of St. Louis allowed three unearned runs in 4 1/3 innings.
St. Louis picked up a first-inning out when Harper walked on a 3-2 pitch with Turner running from first. Despite the walk, catcher Molina threw to Munoz. The Cardinals appealed the play, and upon review Turner was called out. Though entitled to second base via Harper's walk, Turner slid past the bag and was tagged out.
Cardinals: Manager Mike Shildt said 2B Kolten Wong (left hamstring strain) will be activated Wednesday.
Cardinals: RHP Miles Mikolas (13-4, 2.96 ERA), who was originally listed as Tuesday's starter, will instead go in Wednesday's finale. He gave up four runs in seven innings to Washington on Aug. 13.
