2021 MLB Draft: Mock Draft 1.0

The 2021 MLB draft is nearly six months away. The draft has intriguing talent at the college and high school levels, which will make the spring season fun to watch in preparation for the draft.

Remember, the Houston Astros forfeited their first-round and second-round picks last year and this year due to the illegal sign-stealing incident.

If you are looking for more draft content, stay tuned to the Baseball Prospect Journal. There are already 45 (and counting) in-depth profiles on top 2021 MLB draft prospects published on the Baseball Prospect Journal.

Below is a mock draft of the first round and the first competitive balance round.

First Round

1. Pittsburgh Pirates: Kumar Rocker, RHP, Vanderbilt

Rocker will enter the spring season as the favorite to go first overall to the Pirates in July. The right-hander had a notable freshman season, which included winning the College World Series Most Outstanding Player award, and was off to another strong year last spring until the pandemic caused college baseball to seize play.

Rocker has the makeup, size and intangibles to thrive as a starting pitcher at the major-league level. He has a low-effort delivery and a four-pitch repertoire that’s headlined by his mid-90s fastball.

Learn more about Rocker by reading an in-depth feature story at BPJ.

2. Texas Rangers: Jordan Lawlar, SS, Dallas Jesuit (Texas) HS

Lawlar excelled on the showcase circuit last summer to position himself as the top prep player in the 2021 MLB draft class entering the spring. The prep star from Texas has five-tool potential and will stick at shortstop in pro ball.

Learn more about Lawlar by reading an in-depth feature story at BPJ.

3. Detroit Tigers: Jud Fabian, OF, Florida

Fabian enrolled at Florida early in 2019, removing himself from that year’s draft. Now three years later, Fabian is one of the top players in the 2021 MLB draft class. He has five-tool potential and will stick in center field long-term. He worked on refining his plate discipline this offseason, he told BPJ.

4. Boston Red Sox: Jack Leiter, RHP, Vanderbilt

Some professional scouts believe Leiter is a better pro prospect than his Vanderbilt teammate Kumar Rocker. He wanted to attend Vanderbilt out of high school instead of starting a pro career in 2019.

Leiter has a clean delivery, mid-90s fastball, and a really good curveball. The righty also flashes potential with his slider and changeup. He has an exceptional feel for pitching, which partly has to do with learning the craft from former MLB pitcher and his father Al Leiter. 

5. Baltimore Orioles: Matt McLain, SS, UCLA

McLain turned down $2.6 million from the Diamondbacks to honor his commitment to UCLA out of high school. McLain is strong defensively, possessing the instincts and arm strength to stay at shortstop long-term. He also is athletic and has solid speed. He profiles more as a gap-to-gap hitter who will hit for average in pro ball.

6. Arizona Diamondbacks: Brady House, SS/RHP, Winder-Barrow (Ga.) HS

House is a 6-4, 210-pound two-way player who is intriguing in the field and on the mound. Offensively, he hits for average and power from the right side of the plate. Defensively, he currently plays shortstop and handles the position well, possessing a strong arm and smooth actions in the field.

On the mound, House has hit 96 mph with his fastball and mixes in a breaking pitch and changeup. He is a Tennessee commit. 

The spring season will be critical for House after he struggled against high-end pitching at times last summer. It’s hard to deny his potential, but scouts will want to consistently see him perform on the field to feel comfortable making him a top-10 pick.

7. Kansas City Royals: Adrian Del Castillo, C, Miami

Del Castillo is an offensive-minded catcher who has dominated college pitching the last two years. Scouts are split on his defensive skills behind the plate, though. He needs to show improvement defensively this spring. He spent time working with Royals catcher Salvador Perez last summer to refine his defensive skills.

Learn more about Del Castillo by reading an in-depth feature story at BPJ.

8. Colorado Rockies: Alex Binelas, 3B, Louisville 

Binelas, a Wisconsin native, can drive the ball to all parts of the field. He is one of the best power hitters in the 2021 MLB draft class. He does feature some swing and miss in his game, but it’s hard to deny his potential at the plate as a power-hitting corner infielder.

Learn more about Binelas by reading an in-depth feature story at BPJ.

9. Los Angeles Angels: Marcelo Mayer, SS, Eastlake (Calif.) HS

Mayer impressed scouts on the showcase circuit last summer to enhance his draft status. He has a balanced set of tools and will stick at shortstop long-term. Mayer’s best tool is his hitting ability, as he uses a smooth and easy left-handed swing to consistently barrel up pitches and drive the ball to all fields.

10. New York Mets: Ty Madden, RHP, Texas

Madden has made notable strides in his development in his first two years at Texas. He has the size and diverse repertoire of pitches to thrive as a starter in pro ball. He also has improved his command and control in his time at Texas.

11. Washington Nationals: Jaden Hill, RHP, LSU

Hill could easily be a top-five pick in the 2021 MLB draft. But to accomplish that, Hill needs to prove to scouts that he can remain healthy for an entire season and thrive in a large sample size. He has ace potential.

Learn more about Hill by reading an in-depth feature story at BPJ.

12. Seattle Mariners: Henry Davis, C, Louisville

Davis is a complete player. His best trait is his above-average arm strength that is accurate and has allowed him to throw out 34% of base stealers in his first two years at Louisville. He has all the traits to stick at catcher long-term. Offensively, Davis has strong plate discipline and the raw power to make an impact as a right-handed hitter.

13. Philadelphia Phillies: Andrew Painter, RHP, Calvary Christian (Fa.) Academy

Painter currently is the top prep arm in the 2021 MLB draft class. He has a notable 6-foot-6, 210-pound frame, repeats his low-effort delivery well, and fills up the strike zone. He has a fastball that sits in the mid-90s and shows a solid feel for his changeup, curveball, and slider. 

14. San Francisco Giants: James Wood, OF, IMG Academy (Fla.)

Wood has all the traits scouts seek in a prep prospect. He has size, big-time raw power from the left side of the plate, and the attributes to play right field in pro ball. On the showcase circuit last summer, Wood was one of the standout performers. 

15. Milwaukee Brewers: Ethan Wilson, OF, South Alabama

Scouts rank Wilson’s offensive tools, especially his power, as his best traits. The 6-foot-2, 210-pound left-handed hitting outfielder generates loft in his swing and consistently displays above-average power. He also has a strong understanding of the strike zone and typically remains patient at the plate. Wilson will play a corner outfield position in pro ball.

16. Miami Marlins: Kahlil Watson, SS, Wake Forest (N.C.) HS

Speed is Watson’s biggest asset. He has a strong arm and solid footwork to give him a legitimate chance to stick at shortstop in the future. He has room to add strength to his 5-foot-9, 178-pound frame. The left-handed hitter has an aggressive swing and notable raw power.

17. Cincinnati Reds: Ryan Cusick, RHP, Wake Forest

Cusick is a 6-foot-6, 225-pound right-hander who has improved his craft in his time at Wake Forest after the Reds drafted him in the 40th round of the 2018 draft. His best pitch is his high-90s fastball that has reached triple digits. This spring, Cusick has to show improved command and control of his pitches to solidify himself as a first-round pick.  

18. St. Louis Cardinals: Christian Franklin, OF, Arkansas

Franklin is a 5-foot-11, 185-pound right-handed hitter with a balanced setup, quick hands, and solid bat speed at the plate. He has intriguing five-tool potential and offers an exciting mix of power and speed.

Learn more about Hajjar by reading an in-depth feature story on BPJ.

21. Chicago Cubs: Jackson Jobe, RHP, Heritage Hall (Okla.)

23. Cleveland Indians: Sal Frelick, OF, Boston College

25. Oakland Athletics: Benny Montgomery, OF, Red Land (Pa.) HS

26. Minnesota Twins: Jordan Wicks, LHP, Kansas State

Wicks has dominated opposing hitters in his first two years at Kansas State to position himself as one of the top college arms in the 2021 MLB draft. He doesn’t have premium velocity, as his fastball sits low-90s, but he has the best changeup in the class. If he can increase his fastball velocity this spring, Wicks will move up draft boards.

27. San Diego Padres: Chase Petty, RHP, Mainland (N.J.) HS

Petty’s fastball sits in the high-90s and has reached triple digits. He also has a wipeout slider that plays well off his fastball. The biggest question mark with Petty, a 6-foot, 185-pound righty, is his delivery. There is some effort in his low three-quarters arm slot, which sometimes impacts his command.

28. Tampa Bay Rays: Alex Mooney, SS, St. Mary’s (Mich.) HS

Mooney, a 6-foot-1, 190-pound right-handed hitter, has a simple and compact swing with overall clean mechanics that he repeats consistently each time he steps into the batter’s box.
