The 2019 MLB amateur draft is just over a week away! The Prospect Stock Watch has been devoting time to reviewing the 2018 draft. Earlier this week, we reviewed the second round of the draft. Today’s piece is going to look into which players have so far represented the best value from the third, fourth and fifth rounds.
This piece will naturally favor college picks as they’re generally more advanced and many of the prep players taken in later rounds of the draft require extra time in extended spring training before joining full-season ball. This piece looks at players’ results as well as the potential ceilings they possess based on their tools.
Best third-round pick: Terrin Vavra, SS, Rockies
When the year began, I would have hedged my bets towards Tristan Pompey or Kody Clemens being the steals of the fourth rounds. But Pompey posted a strikeout rate near 50% in High-A ball and earned a trip back to extended spring training to work things out. Clemens is still in High-A but he’s struggled to hit consistently and his 25% strikeout rate is high for someone who’s not a power hitter. That leads us to Vavra, who was drafted out of the University of Minnesota, and with less pedigree – although his brothers played pro ball, too. The middle infielder has shown good pop and a solid plate approach with a BB-K of 21-36 in 41 games. The line-drive rate sits at 24% and once Vavra gets a little stronger, he should start to hit even more balls over the fence. It remains to be seen if Vavra can stick at shortstop but he appears to have the offensive profile to stick at a number of different positions.
Runner Up: Owen Miller, SS, Padres
San Diego though enough of Miller’s strong pro debut in 2018 to jump him over High-A ball and assign him directly to Double-A. He’s barely missed a beat with a .301 average, and has now hit .300 at every level he’s played out. The downside to Miller is that his ceiling is somewhat limited with modest power and limited stolen base acumen. With that said, and although just 13 of his 52 hits have gone for extra bases, he has generated a 27% line-drive rate so there could be more gap pop (ie. doubles and triples) to come as he matures. He’s even more likely to end up at second base, or serve as an offensive-minded utility player.
