Top First Base Prospects in the Minor Leagues

The following are myworld’s top ten first base prospects in the minor leagues.

1. Pavin Smith (D-backs) - Smith was the Diamondbacks first round pick in the 2017 draft. He played for Virginia, mashing more homeruns (13) than he struck out (12) in his junior season. He failed to hit a homerun in his minor league debut last year but hit .312 with 15 doubles and a 27/24 walk to whiff ratio. This year the Diamondbacks were aggressive promoting him to High A where he has hit his first three homeruns. Unfortunately he is only hitting .214 with a slugging percentage of .331. His walk to whiff ratio is still excellent at 25/23. His lack of speed means playing the outfield would be tough requiring his power to break out if he wants to replace Paul Goldschmidt at first base. Defensively he will be average at first base.

2. Nick Pratto (Royals) - Another 2017 first round pick, Nick was drafted seven picks after Smith. He was one of four first basemen selected in the draft, though one may turn into a lefthanded pitcher. Nick does not have to worry about Eric Hosmer blocking him at first base. He slugged four homeruns last year in his minor league debut, but was a little more prone to striking out (58 in 52 games). Though he is not noted for his speed he did steal 10 bases in 14 attempts last year. Defensively he plays his position well. A strong arm and adequate speed makes a move to a corner outfield a possibility. This year he is playing in Low A where he has slugged 7 homeruns with a .426 slugging percentage. Those power numbers will have to improve if he hopes to fill the first base job in Kansas City.

3. Brenadan McKay (Rays) - Brendan was another first baseman drafted in the first round in 2017, the fourth player selected in the draft. The higher selection is based on his ability as a lefthanded pitcher as well. Baseball America voted him the 2017 College Player of the Year. After the draft he started six games (1.80 ERA) striking out 9.5 hitters per 9 innings. He also slugged four homeruns with a .232 average. Defensively he is solid at first base but lacks the speed to move to the outfield. While his bat continues to struggle in 2018 (.233/.300 slugging) his pitching has been stellar (4-0, 0.76). He was used for six starts in Low A, pitching just a little over three innings per start. In High A he has been used in relief twice, working 11 innings. On the bright spot offensively he has a 30/20 walk to whiff ratio (.425 OBA). At some point his bat will click and he will hit for a high average with moderate power. Whether he can handle both hitting and pitching is open to question.

4. Bobby Bradley (Indians) - Bradley was a third round pick in the 2014 draft. The power is there for 20 plus homeruns per year as he has done his last three seasons. Strikeouts are a big problem, though last year was the first time since his rookie season when he struck out less than the number of games he played. A lack of speed makes a move to the corner outfield difficult and his defense at first is below par making the DH the best position for him. He is repeating AA this year where he is struggling with a .176 average. Myworld saw him take a ball out, one of his seven homeruns on the year. If his bat can heat up he has a chance for a major league callup this year.

5. Peter Alonso (Mets) - Myworld does not have a lot of faith that Dominic Smith can hold down the future first base position for the Mets. Peter has more power, though neither player is adept at fielding the position well. There is no speed in the legs of Alonso making a move to the outfield not a consideration, not with the surplus of talented outfielders the Mets have. This year the 23 year old is hitting .333 with 14 homeruns for a .632 slugging percentage. The Mets could look for Peter to fill the first base hole before the season is over. He will need to cut back on the 19 errors he made at first base last year. A trade to an American League team where he can play DH is also a possibility.

6. Josh Naylor (Padres) - The 2015 first round pick from Canada by the Marlins probably has more power than any first baseman on this list. Taking advantage of that power has always escaped him. In two full season leagues his high for one season has been 12 homeruns. His strikeout numbers are not high but making better bat on ball contact would increase those homerun numbers. The Padres traded Andrew Cashner in a five player trade to acquire Naylor. His younger brother Noah should be a first round pick in the 2018 draft. Josh has that Babe Ruth look, but unfortunately in his later years at 6′0″ 260. This year Josh seems to have acquired his power stroke in AA with 9 homeruns in 49 games for a .528 slugging percentage. For a big power hitter he does draw a number of walks (25 walks to 27 whiffs).

7. Evan White (Mariners) - Another right handed bat, Evan was drafted in the first round in 2017. He was the last of the four first baseman taken in the draft, falling two positions behind Nick Pratto. Nick has the defensive chops to win a gold glove at first base, plus the speed to move to the outfield. In his minor league debut he hit 3 homeruns with a .277 average in 14 games. Promoted to the California League to start the 2018 season Evan is hitting .294 with three homeruns. As a college drafted player Evan should rise quickly through the organization, this year starting his season in the California league.

8. Brent Rooker (Twins) - Brent was a supplemental first round pick in the 2017 draft. In his first year the Twins they tried him in the outfield but his lack of speed makes covering ground a challenging task. The Twins have still used him in the outfield this year but his main use has been as a first baseman. Last year Brent hit 18 homeruns in just 62 games with a .930 OPS. The power has dropped in 2018 with 7 homeruns and a .722 OPS in 47 games. A propensity for the swing and miss will always prevent him from hitting for a high average.

9. Jake Bauers (Rays) - Jake was a 7th round pick in 2013 by the Padres. He was traded to the Rays in 2014. Jake has never really hit for power with 14 homeruns his minor league high in 2016. He has a career .416 slugging average. His athleticism and decent speed would make a move to the outfield a possibility. A weak arm makes left field his best bet. The Rays would still like to see him hit for more power before making the major league club. This year Jake has hit 5 homeruns and is slugging .454 in his second season in AAA. This could result in a late season promotion by the Rays. Eventually he may have to move to left field if Brendan McKay finds his way to the major leagues.

10. Jake Gatewood (Brewers) - Jake was a middle infielder when he was drafted as a first round supplemental pick in 2014. Sprouting to a height of 6′6″ forced a move to first base in 2017. With that kind of length the power numbers have creeped up with a minor league high of 15 homeruns last year. This year Jake has already slugged 9 homeruns with a .445 slugging percentage. As an ex-middle infielder Jake has good defensive instincts at first base. He could see some time with the Brewers before the 2018 season ends.
