Each Friday from now until the end of May, Jason A. Churchill, who covers the MLB draft for ESPN Insider, will look at the high school prospects whose stock is up and whose stock is down heading into the draft, which begins on June 4.
The 2012 MLB draft is less than a month away and several top prospects are separating themselves from the pack, while others have seen their stock drop recently.
Prospects see their stock trend up or down in regards to the draft based on several key factors, including performance, signability and injury.
Then there’s the case of Nathan Kirby. We had mentioned this possibility last week, but the James River (Midlothian, Va.) right-hander is dead set on attending the University of Virginia and has told Major League Baseball that he will not be participating in the pre-draft program. Considered a Day 1 talent, Kirby is now virtually ineligible to be drafted, but could be a first-round pick in 2015.
Here’s an overall look at which prospects have helped and hurt their draft prospects since last week.
Jesmuel Valentin, SS, Puerto Rico Baseball Academy (Gurabo, Puerto Rico)
The son of former big-league infielder Jose Valentin has had a strong season and showed well recently, including at the Excellence Tournament in Puerto Rico late last week. He's a teammate of Carlos Correa, perhaps the No. 2 overall prep prospect in the entire class, so Valentin plays mainly second base. He's capable at short, however, and has enough arm to play there long term. He's a switch hitter, and though there are some questions about the lack of future power, there is bat speed to support a pro career.
Jesse Winker, Olympia (Orlando, Fla.)
Winker has performed well down the stretch and early in the postseason for FAB 50 No. 1 Olympia, including a 2-for-3 effort last week in the quarterfinals. He went yard in that game, a three-run shot, and has been consistently productive over the past few weeks. Winker is a Day 1 threat.
Lance McCullers Jr., RHP, Jesuit (Tampa, Fla.)
McCullers’ domination – he didn’t allow an earned run during the regular season -- has continued during the postseason as he went all seven, fanning 13 and allowing just four hits. Amazingly, those were the most hits he’s allowed in a start all season. As one scout in attendance opined, “We got to see him really focus, and bow his neck today, and the results speak for themselves.”
Walker Weickel, RHP, Olympia (Orlando, Fla.)
Weickel, who started the spring as a potential top 15 pick before sliding a bit due to a velocity plateau, tossed a two-hit shutout last week in the regional quarterfinals to support Winker's offensive efforts. Weickel's still sitting 89-92 mph, but is showing better command of his fastball and breaking ball and projects well thanks to ideal size. The Miami commit could still land in Round 1 and is unlikely to be on the board when the second round begins.
Others Trending Up
Paul Blackburn, RHP, Heritage (Brentwood, Calif.)
Chase DeJong, RHP, Wilson (Long Beach, Calif.)
Steven Duggar, OF, Byrnes (Duncan, S.C.)
Daniel Robertston, SS/3B, Upland (Calif.)
Shane Watson, RHP, Lakewood (Calif.)
Wyatt Mathisen, C/SS, Calallen (Corpus Christi, Texas)
Mathisen has played well this year, but coming into the season much of his draft stock was based on profiling well as a catcher. He's been used primarily at shortstop this season, which has robbed scouts the chance to see him behind the plate, where he could project as a first-round pick.
Addison Russell, SS/3B, Pace (Fla.)
Russell's stock doesn't appear to have taken a major hit, but a few area scouts have expressed their doubts on his future position more so than earlier in the year. He's still a potential first-round pick, but clubs will have to really like the bat if they aren't confident he will stick at shortstop.
Matt Smoral, LHP, Solon (Ohio)
Smoral has missed most of the season with a foot injury. And while that isn't likely to cost him first-round status, it may ultimately keep him out of the top half of the round. Scouts were unable to check the progress of his breaking ball and especially the changeup, and the left-hander has lost development time.
Others Trending Down
Clint Coulter, C, Union (Camas, Wash.)
David Dahl, OF, Oak Mountain (Birmingham, Ala.)
Kieran Lovegrove, RHP, Mission Viejo (Calif.)
