Looking at the remaining players, the Rockies should have little trouble supplementing the talent of their farm system. The best player available would even make my top five Purp List. Here is a quick rundown on players worth noting on day two (note, some worthy picks for rounds two and three were covered in yesterday's day one preview and will not be covered here):
Tanner Rahier, 3B, HS:
I did not cover Rahier yesterday because I assumed he would be taken around picks 20-25. That he's still available gives me concerns over his signability, but should he be affordable (Rockies could be saving money on the Butler signing) Rahier slots into the fifth slot of my Purps rankings. Rahier is a ball player in the Arenado-Story mold, where his already good tools play up thanks to his aptitude. A HS SS, he'll likely play 3B in the pros, as his big frame is already filling out.
R.J. Alvarez, RHP, Florida Atlantic:
At some point I expect the Rockies to tap into the deep college relief market, and Alvarez is my favorite. Short and athletic, Alvarez pumps lively 95 mph fastballs out of a ¾ arm slot. Slider looks promising and O.J. Mayo even notes promise to his change. Delivery is fairly violent and not conducive to starting.
Chase DeJong, RHP, HS:
Potentially a tough sign as a USC commit, DeJong may have the best pitch plane in the draft. Tall (6'5) with a high ¾ release, DeJong's fastballs get on hitters quickly. He has room to add strength to keep his fastball in the low 90's consistently. Big fan of his curve out of that arm slot.
Adam Brett Walker, 1B, Jacksonville:
Pretty big risk for a college bat, but Walker may be second only to Roache of college raw power. For all the raw power, Walker has serious problems with pitch recognition. His swing is fairly compact for the amount of power he brings, and he may be one of the best mistake hitters in the draft. If he polishes his approach, payoff could be huge. Outstanding physique and could be plus defender at first.
Sam Selman, LHP, Vanderbilt:
This draft is shallow in college starting pitching with power, which makes Selman more valuable as a lefty that can get his fastball up to 95 mph. The pitch doesn't have as much life as you'd like, but his herky jerky delivery gives him deception and the ball seems to jump out of his hand. Raw and hasn't logged many innings on his arm and can be molded.
Jeremy Rathjen, OF, Rice:
More of a 3-4th round prospect, Rathjen nevertheless has upside not found in many college position players this year. A plus athlete at 6'6, Rathjen has power potential made more usable by his solid hit tool. Could be tried at center, but most often gets compared to Corey Hart as a lanky right fielder with pop.
Kolby Copeland, OF, HS:
Sweet swinging outfielder that is a solid athlete but likely ends up in left field. Somewhat similar to Dillon Thomas last year in that you are primarily buying the bat, but Copeland may have better defensive potential. Bat speed, swing path, extension, and balance are all excellent at the plate.
Duane Underwood, RHP, HS:
Similar to Edwin Diaz in that he's purely an arm strength prospect. Some reports suggest Underwood still has more fastball in him, despite already running the pitch upwards of 97 mph. Everything else lags behind and he would require patience.
D'Vone McClure, OF, HS:
Yet another lanky, toolsy athlete, McClure brings an intriguing offensive package from the right side of the plate. Baseball America compares McClure to Jackson. He's fairly raw from what I've seen and is far less polished offensively in comparison to Copeland. Has more defensive upside and could possibly handle center further up the ladder.
Ryan Burr, RHP, HS:
Compared to Ty Hensley by Perfect Game, Colorado HS-er Burr flashes tools just a tick below the Yankee first rounder. He has a long arm action, but Burr can run the fastball into the mid 90's and spins a good breaking ball at altitude. Would likely have to be overdrafted to get signed, but has #2 starter potential.
Christian Jones, LHP, Oregon:
A real wildcard, Jones suffered an injury prior to the season and may not be healthy enough to pitch until the fall. When healthy, Jones has first round stuff as a lefty with a very lively 93 mph fastball. Not sure he's signable and some risk to assume here, but payoff could be equally big.
