March 14, 2023
Sierra was reassigned to minor-league camp Tuesday.
ANALYSIS
Sierra will most likely return to Triple-A, where he slashed .297/.358/.437 and drove in 45 RBI through 311 plate appearances last season. He also stole 22 bases. There's a chance he appears in some games this season for Atlanta, and if so, most of his value will come from swiping bags.

You might recall that Sierra was arguably the biggest name traded from the Cardinals to the Marlins back in December of 2017 in the Marcell Ozuna deal. Sandy Alcantara and Zac Gallen were also part of that trade. Oops. Sierra has struggled to stick in the majors because he's simply not strong enough to hit the ball with any authority at all. He managed just a .442 OPS over 96 plate appearances for the Angels in 2022, although he was 6-for-7 on stolen base attempts. Sierra has elite speed and stolen base chops, but he's probably never going to get on enough for it to matter.
Sierra has yet to see much playing time in the big leagues, and that trend continued in 2020, appearing in 19 contests. During that time, he went 11-for-44 with four extra-base hits, seven RBI and four stolen bases. While the general consensus on the 24-year-old is that he lacks both the ability to consistently get on base and substantial power, only time will tell if this speedster is able to develop at the dish as his career unfolds. One of the positive aspects of Sierra's approach at the plate is that he does regularly makes contact. His K% sat at 16.7% in 2019 and 17% in 2020. Despite this, it's tough to see much value outside of his speed in most fantasy leagues heading into the 2021 season.
Sierra is one of the fastest players in baseball, with 98th percentile sprint speed according to Statcast. The problem is, only the Atlantic League allows batters to steal first base. Until the majors adopts that same rule, it will be tough for Sierra to have fantasy value. He has no power and a bad hit tool, but he can run and can cover ground in the outfield. He is only 24, so there is still room for growth, but it's tough to envision any upside here because the frame is not there to add power, so pitchers will continue to challenge him in the zone and overpower his bat. Expect Sierra to continue on the low-walk/high-contact path he has established throughout his minor-league career.
Acquired by the Marlins last winter, the defensive-minded Sierra opened the 2018 campaign with Triple-A New Orleans, looking to improve his on-base skills so he can take advantage of his 70-grade speed. Unfortunately, things did not go well as Sierra's plate skills fell back from his Double-A marks, registering a 2.8 BB% along with a 25.0 K% in 367 PA with the Baby Cakes. Despite a scant .628 OPS at the time, Sierra was summoned to South Beach after the All-Star break and took over in center field. Sierra held the job for most of the second half even though he slashed an anemic .190/.222/.211 in 156 PA, with only three steals in five attempts. The Marlins are still in rebuild mode while Sierra has options left, so if he fails to impress in the spring, he could be looking at another stint at Triple-A until he demonstrates the ability to get on base at an acceptable clip.
Sierra already has 64 MLB plate appearances despite the fact that he still hasn't mastered Double-A as a hitter. That usage is a bit unfortunate from a developmental perspective, as Sierra was getting rushed by the Cardinals, playing just 20 games at High-A and struggling to make an impact with his bat at Double-A in between brief MLB callups. Thankfully, that usage will be put to an end after he was dealt to the Marlins as part of the package that sent Marcell Ozuna to St. Louis. The elite defensive center fielder will likely be sent back to Double-A, where he can refine his offensive game, as the Marlins won't be contending anytime soon. He remains a 70-grade runner and excellent contact hitter, so he could end up being a poor man's Billy Hamilton in a few years. While the trade may delay his permanent ascent to the big leagues, it will likely work out better for his development in the long run. He could take over as the Marlins' everyday center fielder at some point in the coming years, and could even develop a little power with his new organization.
Sierra has been an enticing prospect ever since he made his stateside debut in 2013, but last year was the first time he lived up to that promise in a full-season league. He showed that he wasn't ready for Low-A in 2015, but he spent all of 2016 with Peoria and the results were outstanding. Sierra stole 31 bases while notching 36 extra-base hits. He is one of those players whose movements on the field stand out, even to the untrained eye. Sierra combines plus-plus speed with an all-fields approach. As he continues to mature physically, more of his doubles will start going for home runs. The primary concern regarding his chances of being a leadoff hitter at the highest level is his low walk rate, but he is such a good baserunner that he still led the Midwest League with 78 runs. This is a prospect worth targeting in dynasty leagues before the entire package starts to come together as he moves closer to the big leagues.
Sierra’s backers were forced to pump the brakes when he failed an optimistic assignment to Low-A Peoria at the outset of the 2015 season. The athletic outfielder hit .191/.219/.247 with a 27.4% K-rate in 190 plate appearances before he was mercifully re-assigned to rookie level Johnson City. However, the 19-year-old then quickly reminded everyone why he was the Cardinals’ Minor League Player of the Year in 2014. He turned in a .765 OPS with three home runs and 15 steals while cutting his K-rate to 17.6% in 239 plate appearances with Johnson City. Despite failing his first assignment to a full-season league, he proved in the second half that the tools of an across-the-board fantasy contributor are still present. Plus speed and an above-average hit tool highlight the package, but many believe more game power will show as he matures. This year it will be important for Sierra to show that he is ready to handle Low-A pitching in his age-20 season.

Latest Fantasy Rumors
Was making case for 2020 spot
OFMiami Marlins  
September 23, 2019
Sierra, whose season ended this weekend after he suffered a left hamstring strain, had been earning interest from the club for a 2020 role, the Associated Press reports.
ANALYSIS
Sierra was slashing .350/.381/.425 in 42 plate appearances since his season debut Sept. 3, and Miami has numerous spots open for the 2020 season. Turning 24 in April, he could land a fantasy-relevant role for at least part of next year, especially considering he stole 26 bases in 36 attempts for Triple-A New Orleans and could help deeper fantasy players as steals become an even more in-demand commodity. Though he's still young and can reach a new level with some growth, his plate work over his first 262 big-league plate appearances (.247/.282/.271) leaves plenty to be desired, which could present an obstacle for playing time.
