MIAMI -- Walk-off home runs, a go-ahead grand slam, shutout victories and an emotional Major League debut were among the Marlins’ top highlights in 2019.

There were plenty of thrilling games, plays and individual achievements for Miami in an otherwise down year. MLB.com breaks down the Marlins' Top 10 moments of the season.

1. Ramirez walk-off homer in the 12th
Aug. 29 vs. Reds
Harold Ramirez was a walk-off regular for the Marlins. The rookie blasted a home run off Raisel Iglesias to lead off the 12th inning and lift Miami to a 4-3 win. For Ramirez, it was his second walk-off homer of the season, and his third walk-off RBI. The right-handed-hitting outfielder turned on a 95-mph elevated sinker and the ball cleared the wall in left. The Marlins had lost the first six games of the season series to Cincinnati, and they were in danger of losing all seven before Ramirez’s heroics.

2. Ramirez walk-off homer against the Bombas
Aug. 1 vs. Twins
The Twins may have been en route to setting a Major League single-season record with 307 homers, but on this night, it was the Marlins that used the long ball to claim a 5-4 win in 12 innings. After Miami scored three times in the ninth inning to force extra innings, Ramirez crushed a walk-off home run to left-center. The rookie was rewarded for his big hit by being dosed with water and powder. He even was handed a pair of dark sun glasses -- a late-season team ritual -- to pose with after he was mobbed by his teammates at home plate.

3. Cooper go-ahead grand slam in Detroit
May 23 at Tigers
Just when it looked like the Marlins’ five-game winning streak was about to end, Garrett Cooper connected on a two-out grand slam in the ninth inning that rallied Miami to a 5-2 win over Detroit at Comerica Park. The Marlins trailed by two heading into the ninth, but they scored five runs in their final frame, with Cooper providing the big blast off Shane Greene. The Tigers intentionally walked Curtis Granderson, marking perhaps his final plate appearance in Detroit, to load the bases for Cooper. Miami also completed its second straight three-game sweep.

4. Cooper go-ahead homer in extras
Sept. 3 at Pirates
The game looked like it was slipping away from the Marlins after the Pirates claimed a one-run lead in the eighth inning. But in the ninth inning, Miguel Rojas connected on a game-tying home run with two outs, and the difference maker came in the 10th when Garrett Cooper connected. Miami pulled out a 5-4 win at PNC Park. According to Statcast, Cooper’s drive to left-center field went a projected 444 feet. Cooper’s home run helped snap a string of 15 straight road losses.

5. June 12: Yamamoto dazzles in debut
June 12 vs. Cardinals
Jordan Yamamoto was with Double-A Jacksonville when he was boarding a bus to Birmingham, Ala., in preparation for his next start. But before the bus left, Yamamoto was informed there was a change in plans. In front of his teammates, he was told he would not be going to Birmingham. Instead, he was being promoted to the big leagues to face the Cardinals. In his MLB debut, the right-hander threw seven shutout innings with five strikeouts in a 9-0 Miami victory. Not just Yamamoto came to Miami on short notice. His parents were even able to make it to Marlins Park from Hawaii to see the game.

6. Alcantara's second shutout
Sept. 8 vs. Royals
The Marlins used 10 starters on the season, and they had just two complete games. They both were shutouts by the same guy: Sandy Alcantara. On a Sunday afternoon, the right-hander was on the mark, striking out eight. Late in the season, Miami was looking to take some of the workload off the relievers, and Alcantara delivered. Even with a big lead, he stayed on the attack in a 9-0 win over the Royals. The 24-year-old ended up with 102 pitches, including 74 strikes. The win snapped a string of 12 straight starts for Alcantara without one, although he pitched far better than the results showed.

7. Alcantara's first shutout
May 19 vs. Mets
On a Sunday afternoon, Sandy Alcantara made quick work of the Mets, going the distance in a 3-0 shutout that lasted a mere one hour and 59 minutes. Pace of play wasn’t an issue for the hard-throwing right-hander, who made it through nine innings on 89 pitches. It was the second-fewest pitches in a complete game of nine innings by a Marlins pitcher. The team mark is 88 pitches, by Henderson Alvarez, on June 3, 2014, against the Rays in Miami. Alcantara allowed just two hits and fanned eight during in the team’s shortest game of the season.

8. Isan Díaz homers in his MLB debut while his family was being interviewed
Aug. 5 at Mets
Timing, they say, is everything. In his MLB debut, second base prospect Isan Díaz belted a home run off All-Star and reigning Cy Young Award winner, Jacob deGrom of the Mets at Citi Field. As Díaz connected on the homer to right, his father, Raul, hit a high note by repeatedly screaming: “Ohhh! Ohh! Ohh!” while being interviewed by Fox Sports Florida. Raul, and other family members and friends, made the trip to New York from Massachusetts, where Díaz grew up. The rookie’s first hit came in the sixth inning, in his third at-bat. And it was a no-doubt blast to right. From a personal standpoint, it was a moment to remember, especially with his father stealing the show with his excitement. But the Marlins came up on the short end of a 6-2 loss.

9. Prado walk-off sac fly
Aug. 10 vs. Braves
Situational hitting has always been a strength of veteran infielder Martín Prado. And in the 10th inning, Prado drove the ball just far enough to left field to allow Harold Ramirez to sprint home as the winning run. The Marlins, rallying back from four down in the ninth to force extra innings, walked it off against Sean Newcomb and the Braves, 7-6, in front of the largest home crowd of the season (29,720). Ramirez singled to open the 10th and moved to third on Newcomb’s errant pickoff attempt, and with first base open, the Braves pitched to Prado. It was his eighth career walk-off RBI.

10. Riddle's go-ahead homer in extras
June 20 at Cardinals
The night marked the MLB debut of pitching prospect Zac Gallen, who was originally drafted by the Cardinals but was traded to the Marlins in 2017 as part of the Marcell Ozuna deal. But the moment belonged to JT Riddle. In a left-on-left matchup, Riddle connected on a two-run homer off Andrew Miller in a 7-6 win in 11 innings at Busch Stadium. The thriller was decided when closer Sergio Romo picked off Jack Flaherty, a pitcher pinch-running for Yadier Molina, at second base. But the decisive pitch was Miller’s hanging slider. Riddle didn’t miss it, keeping the ball fair down the right-field line.
