MLB Fantasy Baseball 2021: Top 100 Big Board, Positional Rankings, Top Sleepers

Mar 22, 2021

It's fantasy baseball draft season once again, with spring training wrapping up and Opening Day right around the corner.

Before we dive into this year's fantasy rankings, a bit of clarification is needed.

First, everything is based on 10- or 12-team mixed leagues with standard five-by-five rotisserie scoring for hitters (batting average, runs, home runs, RBI, stolen bases) and pitchers (wins, ERA, WHIP, strikeouts, saves).

Second, lineup construction assumes 22 active roster positions, consisting of one each for catcher, first base, second base, third base, shortstop, corner infield, middle infield and utility, along with five outfielders and nine pitchers.

Finally, to be eligible at a particular position, players must have accrued at least 10 games there in 2020 or be projected to play there regularly in 2021.

With that established, it's on to the Big Board, followed by our positional rankings and, finally, five deep sleepers.

16. Wilson Ramos, DET
17. Yadier Molina, STL
18. Max Stassi, LAA
19. Tom Murphy, SEA
20. Pedro Severino, BAL

        

Overvalued: Daulton Varsho, ARI (ADP: 211)It's intriguing to grab a guy with catcher eligibility who could see everyday playing time in the outfield, and Varsho was a highly regarded prospect for a reason. But he looked lost last year with a .188 average and 33 strikeouts in 115 plate appearances. Drafting him as your starting catcher is a huge risk.

Undervalued: Max Stassi, LAA (ADP: 442)The 30-year-old journeyman hit .278/.352/.533 with seven home runs and 20 RBI in 31 games last season, taking over primary catching duties after Jason Castro was traded. He'll split time with Kurt Suzuki but should see the bigger piece of the platoon.

21. Ryan Mountcastle, BAL
22. Carlos Santana, KC
23. Miguel Sano, MIN
24. C.J. Cron, COL
25. Jared Walsh, LAA

             

Overvalued: Vladimir Guerrero Jr., TOR (ADP: 53)Count me among those who believe everything is eventually going to click for Guerrero. Until he takes that next step, though, drafting him ahead of Luke Voit (ADP: 57), Paul Goldschmidt (ADP: 73), Anthony Rizzo (ADP: 95) and Max Muncy (ADP: 98) is a stretch.

Undervalued: Jeimer Candelario, DET (ADP: 287)After failing to deliver on his breakout potential in 2019, Candelario was a useful post-hype pickup last year when he hit .297/.369/.503 with seven home runs and 29 RBI. He'll be eligible at first base and third base, which adds to his appeal as a bench option, and the rebuilding Tigers will give him every opportunity to build on his 2020 success.

Second Basemen

Top 25 Second Basemen

18. Dylan Moore, SEA
19. Ha-Seong Kim, SD
20. Kolten Wong, MIL
21. David Fletcher, LAA
22. Jake Cronenworth, SD
23. Enrique Hernandez, BOS
24. Andres Gimenez, CLE
25. Cesar Hernandez, CLE

       

Overvalued: Keston Hiura, MIL (ADP: 67)It's easy to look at Hiura's stellar 2019 debut and write off last year as a fluke. However, ugly exit velocity (26th percentile) and hard-hit rate (50th percentile) metrics raise some bigger red flags. Drafting him ahead of guys like Ketel Marte (ADP: 74), Jose Altuve (ADP: 88) and Max Muncy (ADP: 98) is an unnecessary risk.

Undervalued: Jonathan Schoop, DET (ADP: 352)Schoop averaged 30 doubles, 25 home runs and 77 RBI in the four years leading up to the shortened 2020 campaign, and he hit .278/.324/.475 with eight home runs and 23 RBI in 44 games last year. If you want a contingency plan for someone like Gavin Lux or Nick Solak, he's a great target.

21. Justin Turner, LAD
22. Austin Riley, ATL
23. J.D. Davis, NYM
24. Kyle Seager, SEA
25. Eduardo Escobar, ARI

          

Overvalued: Yoan Moncada, CWS (ADP: 93)After hitting .315/.367/.548 with 64 extra-base hits in 2019, Moncada crashed back to earth with a .225 average and a sub-.400 slugging percentage last year. Those stellar 2019 numbers were propped up by a ridiculous .406 BABIP, so don't assume he's going to return to that level of production.

Undervalued: Brian Anderson, MIA (ADP: 260)Anderson is not 100 draft spots less productive than guys like Tommy Edman (ADP: 148) and Gio Urshela (ADP: 155). The 27-year-old hit .255/.345/.465 with 11 home runs and 38 RBI last season, and he tallied 33 doubles and 20 home runs in 2019.

20. Jorge Polanco, MIN
21. Willi Castro, DET
22. Kevin Newman, PIT
23. Andres Gimenez, CLE
24. Elvis Andrus, OAK
25. David Fletcher, LAA

        

Overvalued: Adalberto Mondesi, KC (ADP: 28)—Mondesi has shown zero ability to adjust his approach to this point in his career, posting an ugly .294 on-base percentage last year while striking out at a 30 percent clip. The steals are great, but with Bobby Witt Jr. coming fast, he's not going to hold onto his everyday job unless he makes significant adjustments.

Undervalued: Kevin Newman, PIT (ADP: 552)Baseball fans have quickly forgotten Newman hit .308/.353/.446 with 38 extra-base hits and 16 steals in 531 plate appearances as a rookie in 2019. He's been red-hot this spring with 11 hits in 16 at-bats and looks like the guy at shortstop for the rebuilding Pirates.

46. A.J. Pollock, LAD
47. Jesse Winker, CIN
48. Brandon Nimmo, NYM
49. Joc Pederson, CHC
50. Jeff McNeil, NYM

         

Overvalued: Luis Robert, CWS (ADP: 39)—A .136 average with 32 strikeouts over 94 plate appearances in September should give reason for pause. Robert is going to be a special player, but it could take him a few years to reach his full offensive ceiling. Kyle Tucker (ADP: 40), Marcell Ozuna (ADP: 43) and George Springer (ADP: 44) are better picks in that same range, and I'm even more optimistic about Trent Grisham (ADP: 66) in 2021.

Undervalued: Hunter Renfroe, BOS (ADP: 354)Lost in the shuffle in a crowded Tampa Bay outfield and non-tendered at the start of the offseason, Renfroe is just a year removed from a 33-homer season. His plus defense should help keep him in Boston's everyday lineup.

47. Chris Bassitt, OAK
48. Corey Kluber, NYY
49. Marcus Stroman, NYM
50. Mike Soroka, ATL

          

Overvalued: Zach Plesac, CLE (ADP: 76)Among pitchers who threw at least 50 innings last season, Plesac had the fourth-lowest BABIP (.224) but a middling exit velocity allowed (58th percentile). You should be skeptical of that combination of statistics. He's a good pitcher, but regression is coming.

Undervalued: Tyler Mahle, CIN (ADP: 178)Lost in the shuffle of Trevor Bauer, Luis Castillo and Sonny Gray at the top of the rotation, Mahle posted a 3.59 ERA with 60 strikeouts over 47.2 innings in 2020. We have not yet seen the best the 26-year-old has to offer.

21. Drew Pomeranz, SD
22. Greg Holland, KC
23. Alex Colome, MIN
24. Matt Barnes, BOS
25. Daniel Bard, COL

         

Overvalued: Kenley Jansen, LAD (ADP: 117)One of baseball's elite closers for the better part of the last decade, Jansen is clearly in decline. Manager Dave Roberts seemed to lose confidence in him during the postseason, turning to Julio Urias and others in clutch situations, and the decision to re-sign Blake Treinen means another potential in-house replacement.

Undervalued: Amir Garrett, CIN (ADP: 253)With Raisel Iglesias traded and Archie Bradley non-tendered, Garrett appears to have a clear path to the closer's role. The 6'5" left-hander has elite stuff with a mid-90s fastball and a lethal slider, and the Reds have a good-not-great outlook that suggests they'll be playing a lot of close games.

5 Deep Sleepers to Know

10 of 10
Ronald Guzman
Ronald Guzman

These players were not ranked in the top 100 overall or among the positional rankings, but they are worth monitoring on draft day:

1B Ronald Guzman, TEX

It looked like Guzman might be on the outside looking in after Nate Lowe was acquired from Tampa Bay, but he is hitting .321 with three home runs this spring while showcasing a revamped swing. The 26-year-old won Dominican Winter League MVP honors, hitting .360/.450/.523 with five home runs and 13 RBI in 30 games for Gigantes del Cibao, and he appears poised to break out.

       

OF Josh Naylor, CLE

Buried down the depth chart in San Diego, Naylor finally has an opportunity to prove himself in Cleveland after he was acquired in the Mike Clevinger blockbuster last summer. The 23-year-old went 5-for-7 with three doubles and one home run in the postseason last year, and he has the raw tools to be a dangerous middle-of-the-order threat.

       

OF Myles Straw, HOU

The Astros opted against finding an outside replacement for George Springer in center field, instead turning things over to Straw. He had a 70-steal season in 2018 between Double-A and Triple-A, and he's a .305/.394/.379 hitter in five minor league seasons. He won't help in power categories, but the batting average and speed should translate.

         

SP Drew Smyly, ATL

Overshadowed by the strong bounce-back season Kevin Gausman put together, Smyly was also a great buy-low pickup for the San Francisco Giants last year. Pitchers don't suddenly post a 42-to-9 strikeout-to-walk ratio in 26.1 innings by accident. Something clicked last year, and that's why the Atlanta Braves were willing to hand him $11 million on a one-year deal.

      

SP/RP Tejay Antone, CIN

Antone put together an excellent rookie season with the Reds last year, posting a 2.80 ERA and 1.02 WHIP with 45 strikeouts in 35.1 innings spanning four starts and nine relief appearances. The Sonny Gray injury could open the door for him to break camp with a rotation spot, and he has the swing-and-miss stuff to seize the role and never look back. Even if he winds up back in a relief role, he'd be a useful roster piece with hold and save potential in a revamped bullpen.
