Predicting the Marlins' Opening Day roster

Alfaro projects as starting catcher, while Granderson enters camp in competition for OF

February 10th, 2019

MIAMI -- The Marlins are set to start Spring Training on Wednesday with 66 players, including 35 pitchers. Before taking the field for the first time at the Roger Dean Chevrolet Stadium complex, breaks down each position and predicts which 25 will be on the Opening Day roster.
Catcher (2):,
Acquired from the Phillies as part of the trade on Thursday, Alfaro will hit the ground running, having to learn a new organization and the pitching and coaching staffs. The other catcher on the 40-man roster is Wallach, who actually was Miami's Opening Day and closing-day catcher in 2018. Wallach is a defensive catcher who grades extremely well in pitch-framing metrics.

First base (2):,
Nothing is guaranteed for O'Brien, a South Florida native who made the most of a September callup last year, belting four home runs and driving in 10 that month. Walker, a free-agent signee, is a left-handed-hitting option who came up as a second baseman with the Pirates.

Second base (1):
A four-time All-Star, Castro enters his second season with the Marlins, and he projects to hit in the middle of the order, perhaps third. Castro had 32 doubles, 12 home runs and 54 RBIs last season. If he has a strong first half, he could become a potential trade candidate.
Third base (1):
Although he played 71 games at third base compared to 91 in right field in 2018, the Marlins will enter Spring Training with Anderson as their third baseman. Perhaps that will change depending on the health of , but for now, Anderson is getting the nod.
Shortstop (2):,
This is a big camp and season for Riddle, who had left shoulder surgery in 2017 and was limited to 102 games last year. He is hardly a lock to get a majority of the time at shortstop, with Rojas coming off a solid season in which he hit .252 with 11 home runs and 53 RBIs.

Outfield (4):, , ,
After a sluggish rookie season in which he batted .199 with 11 home runs and 42 RBIs, Brinson is expected to get every opportunity to be the regular center fielder. But he may be on a shorter leash this year. Herrera, a switch-hitter who played briefly for the Reds and Royals last season, will get a chance to win a starting spot. Dean was promoted to the big leagues last August and saw regular time in left field. Although Granderson is a non-roster invitee, the veteran outfielder is an option to platoon in left field.

Starting pitchers (5):, , , ,
For the second straight season, Urena projects to be the Opening Day starter. The right-hander stepped up in the second half last year and finished with a team-high 31 starts and 174 innings. Straily and Chen are veterans with track records who add experience that will help take pressure off an inexperienced group of starters. Alcantara and Richards both were rookies in 2018 and each showed promise, as well as predictable struggles.
Relief pitchers (8):, , , , , Jose Quijada, ,
The closer spot in Miami's bullpen is up for grabs, with Steckenrider the early frontrunner to handle the role. But the team may also go by matchups, and Conley is a left-handed option. Guerrero is the hardest thrower of the unit. Garcia is another left-handed option, and Quijada is looking to make the jump from Triple-A to be another lefty relief candidate. Romo, who has agreed to a one-year deal, according a source, would fill Miami's need for a veteran arm to complement a young bullpen. The club has not confirmed the deal, which is pending a physical.
In the second year of the building process, manager Don Mattingly and his staff once again will be working with a mostly inexperienced squad filled with players who are continuing to gain Major League experience.
