MILWAUKEE (Interstat) — William Contreras delivered a walk-off three-run homer in the bottom of the ninth inning Sunday, lifting the Milwaukee Brewers to a 3-1 victory over the Miami Marlins at American Family Field before a crowd of 36,451.

The game, which lasted 2 hours, 49 minutes, was a pitchers’ duel for eight innings before the Brewers erupted in the final frame. Milwaukee improved to 62-37, while Miami fell to 52-48.

Miami struck first in the top of the third inning. Esteury Ruiz led off the frame with a home run to left field, his fifth of the season, to give the Marlins a 1-0 lead. It was the only offense Miami could muster against Brewers starter Robert Gasser.

Gasser, who entered the game with a 4-3 record, worked five innings and allowed one run on three hits while striking out five and walking none. The left-hander rebounded after a rocky outing July 12 at Pittsburgh, where he was tagged for seven earned runs in three innings.

Miami starter Eury Pérez was even sharper. The right-hander pitched six scoreless innings, allowing just one hit while striking out nine and walking one. He faced the minimum over the first three innings and retired 10 consecutive batters at one point. Pérez departed after the sixth having thrown 88 pitches, with the Marlins still holding the 1-0 lead.

Both bullpens kept the game tight through the middle frames. Miami reliever Michael Petersen worked 1 1/3 hitless innings with one strikeout, and Cade Gibson added two-thirds of an inning with one hit and one strikeout.

Milwaukee’s Chad Patrick tossed two scoreless innings in relief of Gasser, allowing one hit and striking out three. Aaron Ashby followed with a scoreless eighth, giving up two hits while striking out one.

The Brewers’ offense had been stifled through eight innings. Christian Yelich, Jackson Chourio, Brice Turang and Andrew Vaughn managed only scattered baserunners, and the Brewers went 0 for 5 with runners in scoring position before the ninth.

The game changed dramatically in the bottom of the ninth. With Miami leading 1-0, Brewers reliever Pete Fairbanks came on to close for the Marlins. Fairbanks had entered the game in the eighth and recorded a strikeout to start the inning.

Chourio led off the ninth with a sharp line-drive single to center field. Turang then walked on a 3-2 pitch, moving Chourio to second. Vaughn struck out looking for the first out.

Contreras, batting as a pinch hitter, worked the count to 1-1 before driving a Fairbanks fastball over the center-field wall for his 10th home run of the season. The three-run shot cleared the bases and gave Milwaukee a dramatic 3-1 walk-off win. It was Contreras’ third hit of the series.

Fairbanks took the loss, falling to 3-4. He allowed three runs on two hits and one walk in one inning of work, striking out one.

Grant Anderson earned the win for Milwaukee, improving to 3-3. Anderson pitched a scoreless top of the ninth, striking out one and not allowing a baserunner.

The Marlins had opportunities to extend their lead earlier in the game. In the sixth inning, Heriberto Hernández singled and Kyle Stowers walked, putting two on with one out. But Javier Sanoja lined out and Liam Hicks flied out to end the threat.

In the eighth, Miami put two runners on again. Xavier Edwards singled and Hernández singled, moving Edwards to second. Stowers grounded out, advancing both runners, but Sanoja grounded out to third to end the inning.

Overall, Miami outhit Milwaukee 6-4, but the Marlins left seven runners on base and went 0 for 6 with runners in scoring position. The Brewers stranded five.

Milwaukee’s defense turned a key double play in the sixth. With Yelich on first and Chourio hit by pitch, Turang struck out. Vaughn lined to shortstop Sanoja, who doubled off Yelich at third base to end the inning.

The Brewers also survived a replay review in the fourth. Kyle Stowers’ ground ball to third was initially called safe at first, but Milwaukee challenged and the call was overturned.

The game featured two more replay challenges. In the sixth, Yelich’s pitch result was overturned, leading to a walk. In the top of the fourth, the Brewers’ challenge on Stowers’ at-bat was successful.

Miami’s Ruiz finished 1 for 3 with the home run and an RBI. Edwards went 2 for 4. Hernández had two hits in four at-bats. No Marlins batter drove in more than one run.

Milwaukee’s Contreras went 1 for 2 with the home run and three RBIs. Jake Bauers, starting in right field, went 0 for 2. Chourio singled in the ninth and scored the tying run.

The series win was the Brewers’ third straight over the Marlins in this four-game set. Milwaukee took the opener 2-1 in 10 innings Friday, then won 8-6 Saturday. The Brewers have now won nine of their last 12 games overall and hold a 6-2 record against Miami this season.

Miami has lost four consecutive games and nine of its last 12. The Marlins managed only one run in each of the first two games of this series and have been held to three runs or fewer in seven of their past eight contests.

Milwaukee continues its homestand Monday against the New York Mets. Miami begins a three-game road trip Monday at Houston against the Astros.
