2021 Fantasy Baseball Week 1 Prospect Report

Welcome to the 2021 Fantasy Baseball Week 1 Prospect Report.

In this season-long series, I will be going down to the "farm" and will give you a minor league round-up. I will outline several players that could get called up or players that have been called up in the past week.

As of today, the start of the Triple-A season has been delayed until the first week of May. This will coincide with Double-A and Single-A opening day. Teams are also bringing back the alternate/development sites for 2021.

Therefore, most team's top prospects have been assigned to teams alternate sites where they are able to monitor their top prospects more closely.

Andrew Vaughn, 1B/OF, Chicago White Sox

There were rumblings in spring that Vaughn was going to break camp with the big league team. Then, after Eloy Jimenez's injury that has him sidelined for five to six months, Vaughn's path to the majors was made even more apparent.

However, things started abnormally for Vaughn, who ended up not making his big league debut on Opening Day.  He had to wait for the second game of the season to be placed in the starting lineup.

Vaughn is someone that should already be on your radar, as he has been raking since he was drafted in 2019 (3rd overall). He quickly rose through the White Sox system jumping three levels in one year and finished with six home runs and an OPS of .832 in 55 games.

In 2020 he continued to turn heads at the alternate site. The elite-level hitting continued again in 2021 spring training when he slashed .279/.375/.459 with two home runs & six RBI in 72 plate appearances.

I would highly advise you to run, not walk to your waiver wire and see if for some reason 1) he was not drafted 2) he is still available on your waivers, and grab him if you can as he is undoubtedly a plug and play even in shallow leagues.

Yermin Mercedes, OF, Chicago White Sox

Yes, that's right, another White Sox prospect broke spring training camp with the big league club. Mercedes is more of a minor league journey-man as he enters his age 28 season.

He had appeared to make the team as more of an injury fill-in and outfield depth. However, his career is off to a blistering start! Through his first three games, he has gone 9-for-14 and collected hits in his first eight at-bats, including one home run and six RBI with an OPS 1.643.

He is currently worth a speculative add. I'm certain the regression is coming for Mercedes, but he should continue to receive the at-bats and the playing time, so I would add in deeper leagues.

Taylor Trammell, OF, Seattle Mariners

Trammell, now with his third organization in six years, is finally getting his opportunity.  A highly touted prospect since being drafted by the Reds in 2016, Trammell has the pedigree to be an everyday contributor.

He made the Mariners roster as the starting center fielder to begin 2021. His opening weekend was been off to a slow start as he is currently hitting well below the Mendoza line. However, he did rope an RBI double into the right-center gap for his first big league hit.

He is having a hard time adjusting to major league pitching, as he has struck out in six of his 10 at-bats. I think he will eventually make the necessary adjustments as he never had a K% higher than 27%.

I would be adding Trammell in any league where available. He will remain the starting CF for the foreseeable future.

Jazz Chisholm Jr., 2B/SS, Miami Marlins

Miami's fourth ranked prospect did receive a cup of coffee in 2020 (62PA in 21 games). There were rumors floating in early spring that Jazz would not make the major league club to start the season.

However, after a successful spring (821OPS, 3HR, and 4SB in 45PA), while also playing outstanding defense at 2B and SS. The Marlins had no choice but to hand over the starting 2B job to Chisholm.

Even after a strong spring, he is someone I want to see prove he can produce at a high level before adding him. He only has a career .337 OBP with a 27.9K% in the minors. I could see the power-speed combo eventually come to fruition as he continues to bulk up (he averaged 14 home runs and 12 steals a year).

Again if you need help at middle infield and play in a deeper league don't be shy, add where available.

Geraldo Perdomo, SS, Arizona Diamondbacks

Jazz's former teammate at Kane County(Diamondbacks Class-A affiliate) is currently ranked as Arizona's third-best prospect and ranked as the 79th best prospect overall according to MLB Pipeline.

Perdomo got the call to the big leagues last Saturday. Arizona made the move to fill the hole that was left at shortstop when Nick Ahmed hit the IL with right knee inflammation.

However, his time at the major league level is expected to be short. If he can impress the front office enough to stick around, he should be able to offer stolen bases, as he has swiped 66 bags across 3 seasons in the minors.

He also boasts above-average contact skills and can grind out ABs. His batting average has always hovered in the .300 range. The only concern, for now, is his power. He only has eight home runs in 1034 PA.

With that being said, his debut is off to a slow start. He remains hitless in his first five plate appearances. So unless you are desperate for the stolen base upside. I would leave him on the waiver wire for now while monitoring him closely.


Sixto Sanchez, RHP, Miami Marlins

Sixto made his debut for Miami in the abbreviated 2020 season. So technically he does not qualify as a prospect in MLB terms. However, I wanted to include him as his demotion to the alternate site came as a bit of a surprise to most.

After a strong 2020, where he went 3-2 in seven starts including a complete game. Sixto has always had a strong strikeout attribute (career 20.4 K%). In addition, he also had 103K in 114IP across two levels in 2019.

The demotion was more due to timing, as Sixto had visa issues when traveling back from the Dominican Republic. The Marlins want to give Sixto more time to ramp up before re-joining the big league club.

His spring stats weren't overwhelming but they are nothing to scoff at either. In three starts he went 2-0 with a 1.13 ERA and 0.875 WHIP.

The bad news kept coming as he hit a speed bump on his road back to the major leagues. Sanchez has ended up on the IL as he exited his scheduled start after the 2nd inning. The Marlins are listing it as shoulder inflammation.

Obviously, he will need the extra time at the alternate site to get up and running before joining the big league lineup. However, if you have the roster flexibility I would add where available.

Jarred Kelenic, OF, Seattle Mariners

The number four prospect in all of baseball according to MLB Pipeline. After having a great track record in the minor leagues and then again having great success at the Mariners alternate site in 2020. He continued to rake during his time in Spring Training going 6-20 with two homers and an OPS of 1.140.

Clearly, Kelenic is ready for the majors. However, the Mariners decided his time would be better off at the team's minor league camp. This came as a shock to most, as I believe he is more than ready to contribute to the big league team.

I have a suspicion that this demotion is more of a service time manipulation than it is for development purposes. Grab him while you can as he will be slugging home runs in T-Mobile Park in no time.

Deivi Garcia, RHP, New York Yankees

Deivi came into 2021 Spring Training vying for the Yankees fifth starter spot. Due to the injury to Luis Severino and Domingo German returning from suspension, the Yankees have an opening in their rotation.

He did make his major league debut in 2020 and went on to have 33 strikeouts in 34 IP. In addition, he was also excellent at limiting hard contact and displayed solid control by only issuing 6BB in 34IP.

Unfortunately, Deivi did not do enough to impress the front office this spring. Deivi was optioned to the Yankees minor league camp due to his spring training struggles (0-2 with a 3.86ERA and a 1.43WHIP).

With Luis Severino scheduled to be back by the middle of summer.  It is hard to envision Deivi being promoted anytime soon, aside from a spot start or if another rotation member suffers an injury. Therefore he can be relegated to the wavier wire in most leagues.
