Miami Marlins 2021 Season Preview

Marlins 2021 Season

In our Baseball Spotlight Miami Marlins 2021 season preview, we take a look at everything from last season to projections for the 2021 season. Let’s get started!

The Miami Marlins were the biggest surprise of the 2021 season. The squad went 31-29 and made the playoffs under the expanded format. The 60-game slate favored the Marlins more than any other team in the league.

It was evident that the team would not have been as successful throughout 162 games, but this team has a bright future. The Marlins are the worst team in the National League East in 2021 but do not let this trick you into thinking that they cannot compete.

Marlins 2021 Season Preview

The Marlins are unfortunate in the sense that they are members of the best division in baseball. If Miami were playing in the National League Central or even the American League West, the Marlins would post a better record than they will in 2021.

However, the Marlins’ competition will face this season will help them for years to come. The Marlins are not a bad team, and Don Mattingly has trained this team to not lay down for any team they face.

The Marlins made the postseason in 2020 for the first time since 2003. There is excitement surrounding this organization for the first time in a long time. The Marlins are out to prove that last year was not a fluke and play spoiler in the National League East.

The Lineup

The Marlins need a few pieces added to their lineup before taking the next step in the National League East. This should happen if the Marlins perform well in 2021. The club’s new general manager Kim Ng is all-in on winning, and she did an excellent job in her first offseason putting together a team.

The Marlins picked up Starling Marte’s club option, so he will stay with the team for at least one more season. The team will pay him $12.5 million this season. If you are a Miami fan, this shows that the franchise is doing what needs to be done to win games.

Marte’s presence at the top of the order will benefit the Marlins all season if he stays healthy. He has a career on-base percentage of .341, so he will help protect the younger batters in this lineup.

His speed is also a factor that should help the Marlins get on the board. His legs can help him turn a walk or a single into a double if the opposing pitcher forgets that he is on first.

The team’s power hitters will be located in the three, four, and five holes in 2021. These players are Jesus Aguilar, Adam Duvall, and Brian Anderson. Aguilar and Duvall are both former All-Stars. Anderson is the youngest of the three players.

Marlins 2021 Season

He is 27 years old and finished fourth in the Rookie in the Year vote in 2018. Over four seasons, he has slashed .266/.349/.431. I predict that Brian Anderson breaks out for the first time in 2021, after a slightly down year in 2020.

The Marlins are missing a reputable hitter at the bottom of the order. This area must improve in future seasons to contend with the Mets and the Braves at the top of the NL East.

The Pitching Staff

The Marlins rotation is very young in the best possible way. Is this squad going to make mistakes? Yes, this is a given, but the ceiling on this group is overwhelmingly high. There is not one team in the MLB that would not want one of these pitchers on their roster.

The oldest pitcher in the rotation is 25, and the youngest pitcher is 22. These young ages come with many questions when you factor in their previous experience. Four of the five Marlins starters did not throw over 42 innings in 2021.

How will these pitchers hold up when asked to throw close to 180 innings this year? Only time will tell the answer to this question. Although, if you are a baseball fan, you will want to watch the Marlins’ starters develop over the year.

Marlins 2021 Season

Sandy Alcantara has been named the team’s Opening Day starter. Sandy Alcantra, an All-Star from 2019, is the best pitcher on the staff. He tossed 197.1 innings in 2019, with two complete-game shutouts and 151 strikeouts.

The rest of the rotation has not established themselves yet, but they have all shown flashes of their exceptional talent in the minors and the big leagues.

My favorite wing in the rotation is the southpaw, Trevor Rogers, who will be the team’s fifth starter. Rogers threw 28 innings in 2020. Since he only threw 28 innings last year, he is still considered a rookie, so do not be surprised if he is hoisting the Rookie of the Year Award at the end of 2021.

The three relievers to watch out for in Miami are Anthony Bass, Yimi Garcia, and Dylan Floro. Yimi Garcia is coming off a season where he posted a 0.60 ERA in 14 appearances. I think Garcia will close, and he will be set up by Anthony Bass, an offseason addition who comes from Toronto.

Tanner’s Projection: 72-90

I have one thing to tell the NL East about the Miami Marlins. You better watch out and take this team seriously, or they will spoil your postseason dreams.
