National League West

Arizona Diamondbacks – Jon Duplantier, RHP, 23 years old: Duplantier had a shoulder injury coming out in 2015 as a draft-eligible sophomore, went undrafted, and returned to school. That led to him being drafted in the third round by the Diamondbacks in 2016. He’s pitching in his first full pro season, and so far, he’s dominating, splitting time between low-A and high-A with 87 1/3 innings thrown, a 1.34 ERA, 0.89 WHIP, and a 23/95 BB/K ratio.

Colorado Rockies – Ryan McMahon, 2B, 22 years old: McMahon is a guy who has always had big power and the ability to do well with the bat, but finding a defensive spot has been an issue. However, this year, the Rockies may have found a spot by putting him at second base, where he’s playing very well defensively, and he’s hitting very well between AA and AAA, slashing .352/.396/.583 with 33 doubles, two triples, 15 home runs, and 11 stolen bases.

Los Angeles Dodgers – D.J. Peters, OF, 21 years old: A physical “freak” at 6’6″ and 225 pounds, yet able to ably man center field, Peters is on his second year of drawing rave reviews after being picked in the 4th round last summer. He has a high strikeout rate, but with the production he’s put forth, the Dodgers will take that as he’s hit .285/.394/.543 with 20 doubles, five triples, and 19 home runs in just 91 games in high-A.

San Diego Padres – Adrian Morejon, LHP, 18 years old: Easy choice here as Morejon was in strong consideration for my top 50 with just six professional appearances under his belt. Morejon has incredible stuff, but more impressive than his raw stuff is his ability to control that stuff. It will be impressive to watch Morejon as he goes through his first year in pro ball, and it would not surprise if he’s a top 50 guy at the end of the year.

San Francisco Giants – Bryan Reynolds, OF, 22 years old: Blessed with a balanced skillset, Reynolds slipped to the second round, in spite of high-level production with one of the best programs in the nation in Vanderbilt. He’s produced well this season in high-A, likely earning a AA promotion soon. He’s hitting .305/.353/.455, 19 doubles, 8 triples, and five home runs.
