Day one of the 2013 MLB First Year Player Draft is in the books and Colorado made three picks, including arguably the draft's top prospect in RHP Jonathan Gray of Oklahoma. Upon signing, Gray will immediately become the top ranked prospect in Colorado's system.

Here's a quick recap of who the Rockies took in case you missed the fun:

Round 1, Pick 3: Jonathan Gray, Oklahoma RHP

David OhNo pick analysis

Why you should be excited: On his best day, Gray is unhittable. He can touch triple digits, but sits more around 94 to 98 miles per hour with late life. His devastating slider was unfair in Big 12 play, and that pitch can also reach 91 mph. Gray also possess a promising change, but could get by on just two pitches at OU. At 6'4 and 230 pounds, Gray has a workhorse build, but was surprisingly efficient in college and can throw complete games in fewer than 120 pitches.

Round 2, Pick 42: Ryan McMahon, HS 3B

David OhNo pick analysis

Why you should be excited: McMahon has 50 grade tools across the board, but plus makeup and upside potential. He has a 6'3" frame capable of holding 215-220 lbs. (he's listed at 195 lbs right now), and he could grow into 60 pop. He could also reach 60 grades on defense and should have no problem staying at third base. McMahon's swing is balanced from the left side and has natural loft, so line drive/power potential is evident here.

Round 2B - Competitive Balance B, Pick 70: Alex Balog, University of San Francisco RHP

David OhNo pick analysis

Why you should be excited: Balog was considered a potential first rounder a month ago before tiring down the stretch. Still, Balog was available roughly 30-40 spots later than he should have been. It's not often you get the chance to draft a tall collegian with a mid 90's sinking fastball, but Rockies did just that. Balog also shows promise in his breaking pitches, and despite his size, he's highly athletic and can repeat his delivery and should develop a solid change. Athleticism still gives him some upside.

Heading into round two, here are Baseball America's top players still available. With the 77th pick (the 4th of the third round), the Rockies will be in prime position to snag one of these players.
